General Description
The HMC427LP3 is a low loss broadband posi-
tive control transfer switch in a leadless surface
mount package. Covering DC to 8 GHz, this
switch offers high isolation and low insertion loss.
The switch operates using a positive control volt-
age of 0/+5V and requires a fixed bias of +5V @
< 20 µA.

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