General Description
The HMC345LP3 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. This switch also includes an on
board binary decoder circuit which reduces the
required logic control lines to two. The switch
operates using a positive control voltage of 0/+5V,
and requires a 鏗亁ed bias of +5V.

SWITCHES - SMT
* Blocking capacitors are required at ports RFC and
RF1, 2, 3, & 4. Their value will determine the lowest
transmission frequency.
