Qorvo drops Cascaded Switches with New Wideband 5G High-Isolation Family
Qorvo, a leading global provider of connectivity and power solutions, today announces a new family of RF switches that simplifies multi-band radio architectures. Spanning 50 MHz to 10 GHz, the family reduces component count, improves signal integrity, and enables more efficient RF system design across 5G infrastructure, industrial, drone, and test applications.
As 5G radios expand to support wider bandwidths and more frequency bands, including emerging spectrum such as FR3, designers face increasing challenges maintaining isolation and signal integrity without adding size, loss, and complexity. Many current designs rely on cascaded switch architectures or multiple narrowband devices, increasing insertion loss, degrading linearity and signal integrity, and adding board space and design effort.
“Designers no longer have to rely on cascaded switch architectures to achieve high isolation. We’re delivering that performance in a single device across a very wide bandwidth,” said Debbie Gibson, general manager of Qorvo’s infrastructure business. This approach reduces insertion loss, maintains signal linearity, and simplifies design, improving receiver performance in applications such as digital pre-distortion (DPD) feedback.
Qorvo’s new QPC6144 is a SP4T wideband switch that delivers greater than 65 dB isolation in a single device. Complementing this capability, the QPC6122 (SP2T) and QPC6188 (SP4T) provide wideband absorptive switching across 50 MHz to 10 GHz, enabling a single platform approach to RF routing. These devices reduce component count and simplify design while maintaining low insertion loss and strong linearity across wide bandwidths for calibration paths, general signal routing, and multi-band operation.
The new family of devices forms a dual switching platform that supports both high-isolation and general-purpose routing. By consolidating switching functions into fewer components, engineers can reduce BOM complexity, simplify layouts, and accelerate development across multiple applications.
| Product | Key Role | Solves | Typical Use |
| QPC6144 | High-isolation switching | Eliminates cascaded switches with >65 dB isolation in a single device | DPD feedback, calibration paths, high-isolation paths in 5G radios, and advanced drone communications |
| QPC6122 | Compact wideband switching | Reduces component count while maintaining low insertion loss and signal linearity across wide bandwidths | Calibration paths, space-constrained RF routing in compact RF modules, and drones |
| QPC6188 | Flexible wideband routing | Simplifies multi-path RF routing while maintaining low loss and signal linearity across multiple bands | Switching networks in infrastructure, industrial, drone, and test system applications |

Yes, there really is such a thing as a Lithium-ion capacitor. It's a supercapacitor, not a Li-ion cell.

Janky self-oscillating switching LED driver
| My attempt at making a really minimal switching LED driver (as lean as possible without "abusing" components), for a flashlight or something. I had a lot of fun optimizing it without abusing strange nonlinear effects in components - I would guess the minimum parts you'd need are a choke, (obviously) an LED, sense resistor, flyback diode and 2 transistors (minimum required to create hysteresis). If you were going to use it with 12 volts of Vdd, the component values would be about 470 uH, 10 ohm shunt, 1k pull up resistor, 10k pot, and a feedback resistor in the tens of kohm, this should yield an LED current of a couple hundred milliamps. Let me know if you can remove any more components, or if you find it useful somewhere! [link] [comments] |
PCB etching CNC
| This is a laser I’ve made for milled blank double sided boards with mounting holes for alignment. Previously it’s worked for single sided pcb & now I’ve ben working on making a easy system for double sided & still working on a different homing system for easier flipping of the board. The etching fluid I use hydrogen peroxide with hcl. Main board ESP32, gcode sender I use is laser GRBL , where I just insert a screenshot of my traces and resize based on the dimensions of the blank. It’s generally very easy the most challenging part is still aligning, each board takes about 1hr from blank to etched with no drilling & 80% of time is on waiting. Project files: I’d appreciate a like if anyone uses GrabCAD, it helps my career :) , any feedback or ideas here are also very appreciated! [link] [comments] |
