Non-Refl ective Design
4 x 4 x 1 mm QFN SMT Package
General Description
The HMC232LP4 is a broadband high isolation
non-refl ective GaAs MESFET SPDT switch in
a low cost leadless QFN surface mount plastic
package. Covering DC to 12 GHz, the switch
features >60 dB isolation up to 3 GHz and >42
dB isolation up to 12 GHz. Input P1dB compression is +27 dBm typical, while input IP3 is +50
dBm. The switch operates using complementary
negative control voltage logic lines of -5/0V and
requires no bias supply.

N/C
This pin should be connected to PCB RF ground to maximize
isolation.
Package bottom 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.

* Circuit Board Material: Rogers 4350
The circuit board used in the fi nal application should be
generated with proper RF circuit design techniques. Signal
lines at the RF port should have 50 ohm impedance and
the package ground leads and package bottom should be
connected directly to the ground plane similar to that shown
above. The evaluation circuit board shown above is available from Hittite Microwave Corporation upon request.
