Typical Applications

The HMC253QS24 / HMC253QS24E is ideal for

DC - 2.5 GHz applications:

• CATV/DBS

• CDMA

• Cellular/PCS

The HMC253QS24 & HMC253QS24E are low-cost

non-reflective

SP8T

switches

in

24-lead

QSOP

packages featuring wideband operation from DC

to 2.5 GHz. The switch offers a single positive bias

and true TTL/CMOS compatibility. A 3:8 decoder

is integrated on the switch requiring only 3 control

lines and a positive bias to select each path. The

HMC253QS24 & HMC253QS24E SP8T will replace

multiple configurations of SP4T and SPDT MMIC

switches.
