Functional Diagram
General Description
The HMC244G16 is a non-reflective 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 positive
5V bias to select each path, replacing 8 control lines
normally required by GaAs SP4T switches.
Electrical Specifications, TA = +25° C, With 0/+5V Control, 50 Ohm System
