General Description
The HMC252QS24 & HMC252QS24E are low-cost
non-reflective SP6T switches in 24-lead QSOP
packages featuring wideband operation from DC to
3.0 GHz. The switch offers a single positive bias
and true TTL/CMOS compatibility. A 3:6 decoder
is integrated on the switch requiring only 3 control
lines and a positive bias to select each path. The
HMC252QS24 & HMC252QS24E SP6T replaces
multiple configurations of SP4T and SPDT MMIC
switches and logic drivers.

The circuit board used in the final application should
be generated with proper RF circuit design tech-
niques. Signal lines at the RF ports should have 50
ohm impedance while the package ground leads
should be connected directly to the ground plane
similar to that shown above. A sufficient number of
VIA holes should be used to connect the top and
bottom ground planes. The evaluation circuit board
shown above is available from Hittite Microwave
Corporation upon request.
