General Description
Functional Diagram
The HMC347LP3 is a broadband high isolation
non-reflective GaAs MESFET SPDT switch in
a low cost leadless QFN surface mount plastic
package. 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.

The circuit board used in the final 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.
* Circuit Board Material: Rogers 4350
