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.

105674 Evaluation PCB
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 available from
Hittite Microwave Corporation upon request.
