General Description
The HMC322LP4 is a broadband non-reflective
GaAs MESFET SP8T switch in a low cost lead-
less 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 fixed bias of -5v. This switch
is suitable for usage in 50-Ohm or 75-Ohm sys-
tems.
