Functional Diagram
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.

The circuit board used in the final application
should be generated with proper RF circuit design
techniques. Signal lines at the RF port should
have 50 ohm impedance and the package ground
leads should be connected directly to the ground
plane similar to that shown above. The evaluation circuit board shown above is available from
Hittite Microwave Corporation upon request.
