General Description
The HMC241QS16 & HMC241QS16E are general
purpose low-cost non-reflective SP4T switches in
16-lead QSOP packages. Covering DC - 3.5 GHz,
this switch offers high isolation and has a low insertion
loss of 0.5 dB at 2 GHz. The switch offers a single
positive bias and true TTL/CMOS compatibility. A 2:4
decoder is integrated on the switch requiring only 2
control lines and a positive bias to select each path,
replacing 8 control lines normally required by GaAs
SP4T switches.
