General Description
The HMC322LP4 & HMC322LP4E are broadband non-refl ective 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 fi xed bias of -5V. This switch is suitable for usage in 50-Ohm or 75-Ohm systems.
