Anritsu expands its signal generator product line with the introduction of the EcoSyn Lite Microwave Synthesizer Module that delivers outstanding phase noise, ultra-fast switching speed and compact size. EcoSyn Lite compliments Anritsu’s high performance RubidiumTM bench top signal generators to address a wide range of signal generator applications.

EcoSyn Lite covers 10 MHz to 20 GHz frequency range and delivers +18 dBm output power. Housed in a portable, compact 4 inch x 4 inch x 0.8 inch form factor ideal for use in space constrained applications which require instrumentation grade CW signal source.

Instrument Class Phase Noise in Module Form Factor

EcoSyn Lite features best in class phase noise performance of -126 dBc/Hz (typical) at 10 GHz and 10 kHz offset, that compares favorably with some of the bench top signal generators in the market today. With its robust output power of up to +18 dBm it is ideal as LO for up/down converters in RF/Microwave transceivers. These transceivers increasingly use complex and high order modulation signals which require LOs with low phase noise for up/down conversion. EcoSyn Lite’s superior non-harmonic spurious of -60 dBc delivers very low jitter and can be used as a clock source for Gbit ADC/DAC testing and in high-speed optical systems.

Ultra-fast Frequency Switching Speed

EcoSyn Lite has ultra-fast frequency switching time of less than 50 µs in Triggered list mode. In ATE (Automatic Test Equipment) application, fast frequency switching speed saves testing time. Shorter test times translate to higher test throughput thus achieving less test cost. Ultra-fast switching time and small form factor makes EcoSyn Lite ideal in ATE rack applications.

Switching speed can also be critical in radar cross section (RCS) measurements necessary to establish radar signatures for known targets, such as aircraft, ships, and missiles. These signatures are created through measurements at thousands of frequencies. Because of the total numbers of measurements that must be made, EcoSyn’s ultra fast switching time can save considerable measurement time. Testing an antenna also requires large amounts of data at multiple frequencies. EcoSyn Lite’s ultra-fast switching speed can save a lot of testing time.

Efficient, compact and Easy to Automate

EcoSyn Lite synthesizer modules are housed in portable, compact 4 in x 4 in x 0.8 in form factor which enables them to be used in space constrained applications which require instrumentation grade CW signal source. It supports USB and SPI interfaces for remote control and is powered using a +12 VDC source.

EcoSyn Lite supports standard SCPI and QuickSyn native commands which make developing scripts to remotely control and automate very easy and user friendly.

The Central government has introduced major reforms to Special Economic Zone (SEZ) Rules to push India’s aspirations in semiconductor and electronics manufacturing, with the aim of drawing global investments and minimizing procedural bottlenecks for high-tech sectors. The Ministry of Commerce & Industry said that these measures are going to change India’s industrial policy scenario where SEZs shall henceforth be more accessible and investment-friendly.

Major Policy Changes to SEZ Norms

Amendment on Rule 5 of the SEZ Rules, 2006, is among the landmark reforms, which includes the minimum land size to be established for a semiconductor or electronic component-specific SEZ being curtailed from 50 hectares to just 10. This is expected to benefit the smaller yet highly potential players and thus fast-track building advanced manufacturing hubs.

Another important change is Rule 7, which gives more latitude in acquiring and using land. There will no longer be an encumbrance-free clause attached to mortgaging or leasing land to federal or state government agencies. This will ease a significant regulatory hurdle faced by developers and investors.

In Rule 53, a new method to compute Net Foreign Exchange (NFE) has been introduced so as to include goods being received or supplied free of cost, if such valuation is carried out as per the customs valuation norms. This will align India’s SEZ policy with global best practices and allow easier trade reporting by SEZ units.

On the other hand, Rule 18 has been amended to enable the sale of goods from SEZs into the Domestic Tariff Area (DTA) on payment of the applicable duties. This upgrade will offer enhanced flexibility to the SEZ manufacturers, as well as improve viability of commercial operations by extending market access across the country.

Focus on Capital-Intensive, Long-Gestation Sectors

These strategic reforms notified by the Department of Commerce on June 3, 2025, will be targeted toward industries with higher capital investment needs and long development time frames-such as semiconductor fabrication and advanced electronics.

By minimizing the compliance cover and raising operational flexibility, the government would like to induce global majors and homegrown innovators to invest in the evolving high-tech landscape in India.

The policy shift would also aid job creation, particularly in areas, that are highly skilled. Amongst the jobs created would be those requiring skills in chip design, fabrication engineering and electronics system manufacturing.

Early Gains: Two Major SEZ Projects Approved

In a speedy follow-up to the announcement, the Board of Approval for SEZs has cleared two proposals of major import intended to create the desired impact of the reform:

• Micron Semiconductor Technology India Pvt Ltd would construct a semiconductor LRD of SEZ at Sanand, Gujarat, 37.64 hectares in extent, with an investment commitment of ₹13,000 crore. This unit would become one of the biggest nodes in the Indian-chip making landscape.
• The Hubballi Durable Goods Cluster Pvt Ltd, promoted by Aequs Group, would set up an electronics components SEZ at Dharwad, Karnataka, spread over an area of 11.55 hectares, with an investment of about ₹100 crore.

Such approvals speak of the desire of the government to swiftly translate the policy into action and brand India as reliable partner in the global semiconductor value chain.

Strengthening India’s Global Competitiveness

Due to the soaring worldwide demand for semiconductors and electronics as digital transformation and geopolitical realignments take place, India positions itself, almost by way of strategy, as an option for manufacturing. The new SEZ framework enhances ease of doing business and gives credence to India’s claim to become a self-reliant, technology-driven economy.

These are the steps towards building a strong semiconductor ecosystem, one offering innovativeness, resilience and global relevance.

Recently (5/21/25), I published a Design Idea (DI) describing a bidirectional current mirror using just two transistors and a diode, “A two-way mirror—current mirror that is.”

That circuit works well in some applications, like the one shown in the DI itself, but it nevertheless has limitations due to various error-introducing effects, some of which are described in this reference.

One of the more important factors of these is the “Early effect”, that kicks in to cause significant current imbalance when the voltage drop across the mirror becomes more than a couple of volts. Happily, a fix for the Early effect was devised back in 1967 by George R. Wilson, an IC design engineer at Tektronix. Wilson’s simple yet ingenious fix consisted of adding a third transistor to the basic current mirror, Q3 in Figure 1.

Figure 1 The Wilson mirror improves accuracy despite Early-effect by adding Q3.

Wow the engineering world with your unique design: Design Ideas Submission Guide

Due to Q3, the difference in voltage drop across the active mirror transistors Q1 and Q2 never differs by more than one Vbe, which reduces Early effect error to less than 1%. Figure 2 shows a variation of the basic two-sided current mirror incorporating Wilson’s accuracy-enhancing extra transistor.

Figure 2 A two-way current mirror with Wilson enhancement.

This advantage is exploited in the Figure 3 triangle-wave oscillator to achieve good T-wave symmetry despite as much as 10v being applied across the mirror.

Figure 3 D1, Q3, Q4, and Q5 comprise the two-way Wilson current mirror. It passively conducts Q2’s collector current to C1 via Q3’s base-collecter when OUT versus Vc1 is negative, but becomes an active inverting unity-gain current source when OUT goes positive and reverses the polarity. Keep variable Vin < 4v so Q2 won’t saturate on negative output peaks.

The Wilson mirror is the better choice for Figure 3, but it isn’t always the superior option. That’s because the extra transistor adds an extra Vbe to the minimum voltage drop when the mirror is active. This is no problem for Figure 3 because of its operation from 15v, but would be a deal breaker in the previous DI with its 5v-powered oscillator. Luckily, for the same reason, Early already wasn’t much of an issue there.

Courses for horses?

Stephen Woodward’s relationship with EDN’s DI column goes back quite a long way. Over 100 submissions have been accepted since his first contribution back in 1974.
