New RF Switch Covers 0.3 to 10.6 GHz at 95 nA
The announced PE423213 targets designers seeking low-power, wideband switching, with its first public showing set for electronica 2026.
Updated on Nov. 4, 2026 in Semiconductors
pSemi, a Murata company, has introduced the PE423213, a reflective single-pole double-throw RF switch covering 0.3 to 10.6 GHz. The product is announced, and pSemi will show it publicly for the first time at electronica 2026 in Munich.
Why it matters
RF front-end designers are under pressure to cut power draw, shrink board space, and simplify circuit architectures, and a switch that pairs wide frequency coverage with very low standby current targets all three at once. The launch reflects continued competition among RF switch makers to deliver broadband parts that suit compact wireless hardware.
These are manufacturer-stated typical values from the PE423213 specification, not independently verified measurements. Insertion loss and isolation both degrade as frequency climbs toward 10.6 GHz, and the source does not provide a competitor benchmark for direct comparison.
The players
pSemi (a Murata company)
An RF semiconductor company owned by Murata that builds silicon-on-insulator RF switches and front-end modules using its UltraCMOS+ process.
Messe München
The Munich trade-fair venue that hosts electronica 2026, where pSemi will debut the PE423213.
The details
The PE423213 is a reflective single-pole double-throw switch, meaning it routes a signal between two paths and reflects back the signal when it is off rather than absorbing it. It is built on pSemi's UltraCMOS+ silicon-on-insulator process, a chip-manufacturing approach that places a thin silicon layer over an insulating layer to reduce leakage, and it uses pSemi's HaRP technology enhancements to handle high RF power. The part is housed in a 1.6 x 1.6 mm, 6-lead DFN package and supports operation from -40°C to +105°C with 2 kV ESD protection.
Timeline
November 4, 2026: pSemi announced the PE423213.
November 10-13, 2026: pSemi will first showcase the PE423213 at electronica 2026 at Messe München in Munich.
The Tech Race
The PE423213 extends pSemi's UltraCMOS+ silicon-on-insulator line into a broader frequency band while cutting standby current to 95 nA. The source does not name a specific competing RF switch from another vendor for direct comparison.
Designers of compact RF hardware gain a single part that spans 0.3 to 10.6 GHz instead of stitching together multiple switches, and availability timing and pricing have not been announced. Because the part is only announced, engineers should not expect production samples or volume supply until pSemi publishes those details.
The takeaway
Watch whether pSemi publishes independent measurements or pricing for the PE423213 at electronica 2026 on November 10-13, 2026. Confirmed availability and third-party test results will show whether the 10.6 GHz insertion-loss and isolation figures hold up in real designs.
What happens next
pSemi will demonstrate the PE423213 for the first time at electronica 2026 at Messe München in Munich from November 10 to 13, 2026.
