Product Detail

MA4P504-144
PIN Diode
This series of MACOM semiconductor products is hermetically sealed strip-line package PIN diode designed to drop into a 50 ohm strip-line circuit without 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 reverse DC excitation. They can also be used as attenuators by varying the forward DC current. 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 condition. By applying +10mA to +100mA to center conductor the diode’s impedance changes to a low impedance inductive short causing the diode to reflect RF power. The forward bias current (+10mA to +100mA) must be applied in order to achieve high isolation.
