HMC252QS24 / 252QS24E
v06.1112
GaAs MMIC SP6T NON-REFLECTIVE
SWITCH, DC - 3 GHz
General Description
Features
Functional Diagram
Low Insertion Loss (2 GHz): 0.9 dB
Single Positive Supply: VDD = +5V or +3.3V
Integrated 3:6 TTL Decoder
24 Lead QSOP Package
Electrical Specications I,
TA = +25°C, For TTL Control and VDD = +5V in a 50 Ohm System
Typical Applications
The HMC252QS24 / HMC252QS24E is ideal for:
• Base Station
• CATV / DBS
• MMDS & WirelessLAN
• Test Equipment
The HMC252QS24 & HMC252QS24E are low-cost
non-reective 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 congurations of SP4T and SPDT MMIC
switches and logic drivers.

Evaluation Circuit Board
The circuit board used in the 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.
