General Description
The HMC344LH5 is a broadband non-reflective GaAs
MESFET SP4T switch in a hermetic SMT leadless
package. Covering DC to 12 GHz, this switch offers
high isolation and low insertion loss. This switch also
includes an on board 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. The HMC344LH5 allows the use of surface
mount manufacturing techniques and is suitable
for high reliability military, industrial and space
applications.
