General Description
The HMC427LP3 & HMC427LP3E are low loss
broadband positive control transfer switches in
leadless surface mount packages. Covering DC to 8
GHz, this switch offers high isolation and low insertion
loss. The switch operates using a positive control
voltage 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 fre-
quency.
