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.

List of Material
The circuit board used in the final application should be
generated with proper RF circuit design techniques. Signal
lines at the RF port should have 50 ohm impedance and
the package ground leads and package bottom should be
connected directly to the ground plane similar to that shown
above. The evaluation circuit board shown above is avail-
able from Hittite Microwave Corporation upon request.
