RFSW2042

DC TO 15GHz SP3T PHEMT GaAs SWITCH

RFMD's RFSW2042 is a broadband reflective SP3T GaAs microwave monolithic

integrated circuit (MMIC) switch designed to operate from DC to 15GHz using the

RFMD FD05 0.5m switch process. It features low insertion loss of 2.1dB at 15GHz

and high isolation of 37dB at 15GHz while being packaged in a compact, low cost,

4mm x 4mm QFN package for easy end use assembly. The switch uses comple-

mentary control logic of -5/0V and does not require a separate bias supply.

Features

Low Insertion Loss: 2.1dB at

15GHz

High Isolation: 37dB at 15GHz

Excellent Return Loss

21nS Switching Speed

GaAs pHEMT Technology

Compact 4x4mm QFN package

Applications

Broadband Communications

Test Instrumentation

Fiber Optics

Military

Aerospace
