Functional Diagram
General Description
The HMC344LP3 is a broadband non-re鏗俥ctive
GaAs MESFET SP4T switch in a low cost lead-
less surface mount package. Covering DC to 8
GHz, this switch offers high isolation and low
insertion loss and extends the frequency cover-
age of Hittite鈥檚 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 鏗亁ed bias
of -5V.
