SWITCH, DC - 8.0 GHz
Features
Broadband Performance: DC - 8.0 GHz
High Isolation: >30 dB@ 6 GHz

General Description
The HMC322LP4 is a broadband non-refl ective
GaAs MESFET SP8T switch in a low cost leadless surface mount package. 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 fi xed bias of -5v. This switch
is suitable for usage in 50-Ohm or 75-Ohm systems.

The circuit board used in the fi 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 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.
