General Description
Features
Functional Diagram
The HMC427ALP3E is a low loss broadband positive
control transfer switch in 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 voltage of 0/+5V and requires
a xed bias of +5V at < 20 µA.
High Isolation: 40 ~ 45 dB thru 6 GHz
Low Insertion Loss: 1.5 dB at 6 GHz
Non-Reective Design
3x3mm SMT Package
Electrical Specications, TA = +25° C, VDD = 5V , With 0/+5V Control, 50 Ohm System
Typical Applications
The HMC427ALP3E is ideal for:
• Test Instrumentation
• Fiber Optics & Broadband Telecom
• Basestation Infrastructure
• Microwave Radio & VSAT
• Military Radios, Radar, & ECM
* Blocking capacitors are required at ports RF1, 2, 3, & 4.
Their value will determine the lowest transmission frequency.

Evaluation PCB
The circuit board used in the nal 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 Analog Devices upon request.
