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
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 fixed bias of -5V. This switch is suitable for usage in
50-Ohm or 75-Ohm systems.
