• RoHS Compliant
Description
This series of M/ACOM semiconductor products is
hermetically sealed strip-line package PIN diode
designed to drop into a 50 ohm strip-line circuit with-
out external matching. The MA4P504-144 can be
used as SPST reflective switches and are useful in
applications from VHF through X Band. Several
modules are provided with different power and
switching speed capability.
This series of strip-line switch modules consist of
shunt mounted passivated PIN diodes in hermetic
strip-line packages. These modules are optimized
for 50 ohm micro-strip and strip-line circuits. The
MA4P504-144 series modules maybe operated as a
switch by applying the appropriate forward and re-
verse DC excitation. They can also be used as at-
tenuators by varying the forward DC current.
Applications
The MA4P504-144 broadband shunt-mounted PIN
diode features a shunt-mounted PIN chip with an
appropriate series inductance to produce a matched
low pass filter structure at zero or reverse bias con-
dition. By applying +10mA to +100mA to center con-
ductor the diode’s impedance changes to a low-
impedance inductive short causing the diode to re-
flect RF power. The forward bias current (+10mA to
+100mA) must be applied in order to achieve high
isolation.
