= +25 C, For TTL Control and Vdd = +5V in a 50 Ohm System
Typical Applications
The HMC252QS24 is ideal for:
Base Station
CATV / DBS
MMDS & WirelessLAN
Test Equipment
The HMC252QS24 is a low-cost non-refl ective
SP6T switch in a 24-lead QSOP package fea-
turing 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 inte-
grated on the switch requiring only 3 control lines
and a positive bias to select each path. The
HMC252QS24 SP6T replaces multiple confi gu-
rations of SP4T and SPDT MMIC switches and
logic drivers.

Evaluation Circuit Board
The circuit board used in the fi nal application should be generated with proper RF circuit design techniques. 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 suffi cient 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.
