GaAs MMIC SP4T SWITCH NON-REFLECTIVE DC TO 6.0 GHz
FEBRUARY 2001
Features
BROADBAND PERFORMANCE: DC to 6GHz
SINGLE POSITIVE SUPPLY: Vdd = +5V
INTEGRATED 2:4 TTL DECODER
CERAMIC SMT PACKAGE
HMC222C12
V02.0101
General Description
The HMC222C12 is a broadband non-reflective SP4T switch in a ceramic surface
mount package. This SP4T switch covers
RF telecom/datacom bands from DC - 6
GHz. The switch offers a single positive
bias and true TTL/CMOS compatibility. A
2:4 decoder is integrated on the switch requiring only 2 control lines and a +5V bias to
select each path. An input IP3 of +40 dBm
helps maintain the best possible dynamic
range in receiver & test instrument applications. The integrated 2:4 TTL/CMOS decoder replaces 8 control lines normal required by GaAs SP4T switches.

The circuit board used in the final application should be generated with proper RF circuit design techniques.
Signal lines at the RF port should have 50 ohm impedance and the package ground leads and exposed ground
paddle should be connected directly to the ground plane similar to that shown above. The evaluation circuit board
shown above is available from Hittite Microwave Corporation upon request.
