UM9401 / UM9402 / UM9415
COMMERCIAL TWO-WAY RADIO
ANTENNA SWITCH DIODES
DESCRIPTION
Microsemi offers a series of PIN diodes
specifically designed and characterized for
solid state antenna switches in commercial
two-way radios. Antenna switches using the
UM9401 and UM9415 series PIN diodes
provide high isolation, low loss and low
distortion characteristics formerly possible
only with electromechanical relay type
switches.
The UM9401 and the UM9402 diodes can
handle 100 W of transmitter power, while
The UM9415 will handle over 1000 W. The
extensive characterization of these PIN diodes in
antenna switch applications has resulted in
guaranteed low distortion specifications under
transmit and receive conditions. These diodes
also feature low forward bias resistance and high
zero bias impedance which are required for low
loss, high isolation and wide bandwidth antenna
switch performance.
