HMC322LP4 / 322LP4E
v06.0112
GaAs MMIC SP8T NON-REFLECTIVE
SWITCH, DC - 8 GHz
General Description
Features
Functional Diagram
The HMC322LP4 & HMC322LP4E are broadband
non-reective GaAs MESFET SP8T switches in low
cost leadless surface mount packages. Covering DC
to 8 GHz, this switch offers high isolation and low
insertion loss. This switch also includes an on board
binary decoder circuit which reduces the required
logic control lines to three. The switch operates using
a negative control voltage of 0/-5 volts, and requires
a xed bias of -5V. This switch is suitable for usage in
50-Ohm or 75-Ohm systems.
Broadband Performance: DC - 8.0 GHz
High Isolation: >30 dB@ 6 GHz
Low Insertion Loss: 2.4 dB@ 6 GHz
Integrated 3:8 TTL Decoder
24 Lead 4x4mm QFN Package: 9 mm
Electrical Specications, TA = +25° C, With 0/-5V Control, 50 Ohm System
Typical Applications

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
available from Hittite Microwave Corporation upon
request.
