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

Maximum Transmitter Power
The maximum CW transmitter power, PT(max), a PIN diode
antenna switch can handle depends on the diode
resistance, RS, power dissipation, PD, antennae SWR, σ,
and the nominal impedance, ZO. The expression is as
follows:
transmit; at zero bias the receive insertion loss is less
than 0.3 dB. This performance is achievable across a ±20
% bandwidth at center frequencies ranging from 10 to 500
MHz.

Characteristic curves are shown in the data section
which gives both the maximum and typical diode
resistance, RS as a function of forward current. The
maximum power dissipation rating of the PIN diode
depends both on the length of the diode leads and the
temperature of the contacts to which the leads are
connected. A graph defining the maximum power
dissipation at various combinations of overall lead length
(L) and lead temperature (TL) is given in the data section.
From these curves and the above equation, the power
handling capability of the PIN diode may be computed for
a specific application.

Curves are also presented which show the maximum
transmitter power that an antenna
switch using UM9401s and UM9415s can safely handle
for various forward currents and lead temperatures.
These curves are based on a typical design condition of a
½ in. total overall lead length, 50 Ω line impedance, and a
totally mismatched antenna (σ = ∞). For the case of a
perfectly matched antenna, the maximum transmitter
power can be increased by a factor of 4.

Design Information
A circuit configuration for a two-way radio antenna
switch using PIN diodes consists of a diode placed in
series with the transmitter and a shunt diode placed a
quarter wavelength from the antenna in the direction of
the receiver as shown. For low frequency operation, the
quarter wave line may be simulated by lumped elements.
Typical performance of antenna
C
C
switches using PIN diodes forward biased at 100 mA is
less than 0.2 dB insertion loss and 30 dB isolation during
