HMC244G16
GaAs MMIC SP4T NON-REFLECTIVE
SWITCH, DC - 4.0 GHz
v01.0404
General Description
Features
Functional Diagram
The HMC244G16 is a non-refl ective SP4T switch in
a 16 lead glass/metal (hermetic) package. Covering
DC to 4.0 GHz, the switch offers 30~50 dB isolation
and a low insertion loss of 0.7 dB through 3 GHz. A
2:4 TTL/CMOS compatable decoder is integrated on
the switch requiring only 2 control lines and a posi-
tive 5V bias to select each path, replacing 8 control
lines normally required by GaAs SP4T switches.
Low Insertion Loss: 0.7 dB

Evaluation PCB
The circuit board used in the fi nal 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 package
bottom 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.
