Functional Diagram
General Description
The HMC241QS16 is a low-cost non-re鏗俥ctive
SP4T switch in a 16-lead QSOP package. Cover-
ing 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 inte-
grated 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.
