Functional Diagram
General Description
The HMC347LP3 & HMC347LP3E are broadband
high isolation non-reflective GaAs MESFET SPDT
switches in low cost leadless QFN surface mount
plastic packages. Covering DC to 14 GHz, the switch
offers high isolation and low insertion loss. The switch
features >50 dB isolation up to 3 GHz and >40 dB
isolation up to 13 GHz. The switch operates using
complementary negative control voltage logic lines of
-5/0V and requires no bias supply. This SPDT is an
excellent alternative to the HMC132C8 SPDT.

Description
This pin should be connected to PCB RF ground to
maximize isolation
Package bottom has exposed metal paddle that must also
be connected to PCB RF ground.
This pin is DC coupled and matched to 50 Ohm. Blocking
capacitors are required if RF line potential is not equal to 0V.
