General Description
The HMC245AQS16E is a low cost non-reflective
SP3T switches in 16-lead QSOP surface mount pack-
ages. Covering DC to 3.5 GHz, the switch offers 30 to
40 dB isolation and a low insertion loss of 0.7 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, replacing 6 control lines
normally required by GaAs SP3T switches.
