Typical Applications
The HMC241QS16 is ideal for:
Base Stations & Portable Wireless
CATV / DBS
Wireless Local Loop
Test Equipment
The HMC241QS16 is a low-cost non-refl ective
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.

Evaluation PCB
The circuit board used in the fi
nal 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 evalua-
tion circuit board shown above is available from
Hittite Microwave Corporation upon request.
