Typical Applications
The HMC182S14 is ideal for:
800 - 1000 MHz Basestation
The HMC182S14 is a low-cost terminated SP4T
switch in a 14-lead SOIC package for use in
antenna diversity, switched fi lter banks, gain/
attenuation selection, and general channel multi-
plexing applications. The switch can control sig-
nals up to 2 GHz. A 2:4 decoder is integrated
on the switch, requiring only 2 control lines and
a negative bias to select each RF path. The
2:4 decoder replaces 4 to 8 control lines nor-
mally required by GaAs SP4T switches. The
HMC182S14 is a drop-in replacement for the
HMC165S14 in applications requiring low "off
state" VSWR. See positive bias/TTL SP4T
HMC241QS16.

Evaluation PCB
The circuit board used in the fi nal application should
be generated with proper RF circuit design tech-
niques. 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 Micro-
wave Corporation upon request.
