General Description
Features
Functional Diagram
The HMC321ALP4E is a broadband non-
reective GaAs SP8T switch in low cost lead-
less surface mount packages. Covering DC to
8 GHz, this switch offers high isolation and low inser-
tion loss. This switch also includes an on board binary
decoder circuit which reduces the required logic con-
trol lines to three. The switch operates using a positive
control voltage of 0/+5 volts, and requires a xed bias
of +5 volts. This switch is suitable for usage in 50-Ohm
or 75-Ohm systems.
Broadband Performance: DC - 8 GHz
High Isolation: >30 dB at 6 GHz
Low Insertion Loss: 2.3 dB at 6 GHz
Integrated Positive Supply 3:8 TTL Decoder
24 Lead 4x4mm QFN Package: 9 mm²
Electrical Specications, TA = +25° C, With 0/+5V Control, 50 Ohm System
Typical Applications
This switch is suitable for usage in DC - 8.0 GHz
50-Ohm or 75-Ohm systems:
• Broadband
• Fiber Optics
• Switched Filter Banks
• Wireless below 8 GHz
* DC blocking capacitors are required at ports RFC and
RF1, 2, 3, 4, 5, 6, 7, 8. Their value will determine the lowest
transmission frequency.

Evaluation PCB
The circuit board used in the application should
be generated with proper RF circuit design tech-
niques. Signal lines at the RF port should have 50
ohm impedance and the package ground leads and
backside ground slug 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.
