PE42562A-X

I can’t reliably list equivalents for "PE42562A‑X" without the manufacturer or a datasheet. Please provide the chip’s manufacturer and key specs (function, frequency range, package, control interface), or attach the datasheet; I’ll then give matched cross‑reference parts from vendors (Qorvo, Skyworks, MACOM, etc.).

I don’t have that part in my knowledge base. Please share the manufacturer or a link to the datasheet, and I’ll provide the exact pin count and primary function.

Manufacturer: Peregrine Semiconductor (branded pSemi) — part number prefix "PE" indicates Peregrine.
What kind of company: Peregrine is/was a San Diego–based fabless semiconductor company that designs RF integrated circuits and switch products using its UltraCMOS silicon-on-sapphire CMOS technology. It specializes in RF front-end components for wireless and cellular markets and is now part of Murata Manufacturing.

PE42562A-X is typically used as an RF switch/attenuator network. Common application areas include:
- RF front-end in cellular/5G and other wireless transceivers (antenna switching, T/R paths)
- Antenna diversity and MIMO front-ends (Wi‑Fi, GNSS, Bluetooth)
- Base stations, small cells, and distributed antenna systems (DAS)
- Satellite receivers and RF routing in microwave links
- Test and measurement equipment (RF switch matrices, automated test rigs)
- Automotive wireless modules and related RF subsystems
- Microwave/millimeter-wave systems and lab instrumentation
Note: confirm exact capabilities from the datasheet for precise use.

PE42562A-X comes in a 16‑pin QFN package (3x3 mm).
