General Description
The HMC344LP3 & HMC344LP3E are broadband
non-reflective GaAs MESFET SP4T switches in low
cost leadless surface mount packages. Covering DC
to 8 GHz, this switch offers high isolation and low
insertion loss and extends the frequency coverage
of Hittite’s SP4T switch product line. 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.
