General Description
The HMC245AQS16 & HMC245AQS16E 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 inser-
tion 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.
