Functional Diagram

General Description

The HMC344LC3 is a broadband non-reﬂective GaAs

MESFET SP4T switch in a ceramic 3x3 mm leadless

surface mount package. Covering DC to 8 GHz, this

switch offers high isolation and low insertion loss. The

HMC344LC3 includes an integrated binary decoder

circuit which reduces the required logic control

lines to two. The switch operates using a negative

control voltage of 0/-5V, and requires a ﬁxed bias of

-5V. Simple external level shifting circuitry allows this

switch to be controlled with most TTL/CMOS positive

logic families.

Evaluation PCB

List of Materials for Evaluation PCB 105311 ^[1]

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 backside ground slug 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.
