Features
LOW INSERTION LOSS (2 GHz): 0.9dB
SINGLE POSITIVE CONTROL: Vdd= +5V
INTEGRATED 3:6 TTL DECODER
24 LEAD QSOP PACKAGE
V02.0101
General Description
The HMC252QS24 is a low-cost non-reflective SP6T switch in a 24-lead QSOP package featuring wideband operation from DC
to 3.0 GHz, covering all cellular/PCS (450 to
2000 MHz), wideband CDMA (2000-2300
MHz), industrial, scientific, and medical (900
and 2400 MHz), and CATV/DBS (50 to 2150
MHz) bands. 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 SP6T replaces multiple configurations of SP4T and SPDT MMIC
switches and logic drivers.
