HMC224MS8

GaAs MMIC T/R SWITCH

5.0 - 6.0 GHz

Features

Low Cost 5-6 GHz Switch

Ultra Small Package: MSOP8

High Input P1dB: +33 dBm

Single Positive Supply: +3 to +8V

General Description

The HMC224MS8 is a low-cost SPDT switch in
an 8-lead MSOP package for use in transmit­receive applications. The device can control sig­nals from 5.0 to 6.0 GHz and is especially suited
for 5.2 GHz UNII and 5.8 GHz ISM applications
with only 1.2 dB loss. The design provides excep­tional power handling performance; input P1dB =
+33 dBm at 5 Volt bias. RF1 and RF2 are refl ec­tive shorts when “Off”. On-chip circuitry allows
single positive supply operation at very low DC
current with control inputs compatible with CMOS
and most TTL logic families. No DC blocking
capacitors are required on RF I/O ports.
