Functional Diagram
General Description
The HMC245QS16 & HMC245QS16E are low cost
non-reflective SP3T switches in 16-lead QSOP sur-
face mount packages. Covering DC to 3.5 GHz, the
switch offers 30 to 40 dB isolation and a low insertion
loss of 0.5 dB. A 2:3 TTL/CMOS compatible decoder
is integrated on the switch requiring only 2 control
lines and a single +5V bias to select each path, replac-
ing 6 control lines normally required by GaAs SP3T
switches.
