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 transmit-
receive applications. The device can control sig-
nals 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 excep-
tional power handling performance; input P1dB =
+33 dBm at 5 Volt bias. RF1 and RF2 are reflec-
tive 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.
