Functional Diagram
General Description
The HMC322LP4 & HMC322LP4E are broadband
non-reflective GaAs MESFET SP8T switches in low
cost leadless 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
control lines to three. The switch operates using a
negative control voltage of 0/-5 volts, and requires a
fixed bias of -5v. This switch is suitable for usage in
50-Ohm or 75-Ohm systems.
