Functional Diagram
General Description
The HMC547LP3 & HMC547LP3E are general pur-
pose broadband high isolation non-reflective GaAs
MESFET SPDT switches in low cost leadless QFN
surface mount plastic packages. Covering DC to
20 GHz, the switch offers high isolation and low
insertion loss. The switch features >50 dB isolation
up to 5 GHz and >45 dB isolation up to 15 GHz.
The switch operates using complementary negative
con-trol voltage logic lines of -5/0V and requires no
bias supply. The HMC547LP3 & HMC547LP3E are
packaged in leadless QFN 3x3 mm surface mount
packages.

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.
