Non-Reflective Topology
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.
