General Description
The HMC245QS16 is a low cost non-re鏗俥ctive SP3T
switch in a 16-lead QSOP surface mount package.
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, replacing 6 control lines normally
required by GaAs SP3T switches.
