Features
High Isolation: >80 dB @ 5 MHz (50 Ohm)
>55 dB @ 1 GHz (50 Ohm)
“All Off” Isolation State
Non-Reflective Design, 75 Ohm Terminations
3 mm x 3 mm x 1 mm SMT Package
General Description
The HMC348LP3 is a non-reflective GaAs MESFET
SPDT switch in a low cost leadless QFN surface
mount plastic package ideal for CATV applications.
Covering DC to 2.5 GHz, the switch offers high
isolation, low insertion loss, integrated 75 Ohm ter-
minations and an “all off” state. The switch features
>80 dB isolation at 5 MHz and >55 dB isolation up
to 1 GHz. The switch operates using complemen-
tary positive control voltage logic lines of +5/0V and
requires a +5V bias supply (Vdd). This switch offers
excellent performance in both 50 Ohm & 75 Ohm
systems for either SPDT or SPST functions.
