Typical Applications
The HMC183QS24 is ideal for:
Basestation Infrastructure
The HMC183QS24 is a low-cost non-refl ective
SP8T switch in a 24-lead QSOP package for use
in antenna diversity, switched fi lter banks, gain/
attenuation selection, and general channel mul-
tiplexing applications. A 3:8 decoder is inte-
grated on the switch, requiring only 3 control lines
with a negative bias to select an RF path. The
3:8 decoder replaces 16 control lines normally
required by GaAs SP8T switches. Switch outputs
are terminated when "off". The QSOP24 pack-
age occupies the same area as a 14-lead SOIC.
See positive bias/TTL version HMC253QS24.

Evaluation Circuit Board
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 and
package bottom should be connected directly to the
ground plane similar to that shown above. The evalu-
ation circuit board shown above is available from Hit-
tite Microwave Corporation upon request.
