LOW INSERTION LOSS: 0.4dB
INTEGRATED 2:4 DECODER
14 LEAD SOIC PACKAGE
Features
General Description
The HMC165S14 is a low-cost SP4T switch
in a 14-lead SOIC package for use in an-
tenna diversity, switched filter banks, gain/
attenuation selection, and general channel
multiplexing applications. The switch can
control signals up to 2.5 GHz and is espe-
cially suited for 800-1000 MHz basestation
applications*. A 2:4 decoder is integrated
on the switch, requiring only 2 control lines
and a negative bias to select each RF path.
Switch outputs are reflective shorts when
"Off". The 2:4 decoder replaces 4 to 8
control lines normally required by GaAS
SP4T switches. See positive bias/TTL SP4T
HMC241QS16.
Guaranteed Performance
For 0/-5V Control and Vee = -5V in a 50 Ohm System, -40 to +85 deg C
