COMMERCIAL TWO WAY RADIO
ANTENNA SWITCH DIODES
RoHS Compliant Versions Available
KEY FEATURES
DESCRIPTION
. High transmitter power
Microsemi offers
a series of PIN diodes specifically designed and
UM9401/UM9402 => 100 W
UM9415 => 1000 W
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.
. Low harmonic distortion
. Low third order distortion
. High carrier lifetime
. Non cavity design
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. For RoHS compliant devices, use the UMX prefix. (IE:
UMX9415)
. Thermally matched configuration
. Low capacitance at 0 V bias
. Low conductance at 0 V bias
. Compatible with automatic
insertion equipment
The UMX series meets RoHS requirements per EU Directive 2002/95/EC.
. RoHS complaint versions
available. 1
. Lead finish
