Description
The MA4PBL027 is a silicon beam lead PIN diode
fabricated with MACOM’s HMIC™ process. It
features one silicon pedestal embedded in a low
loss, low dispersion glass which supports the
beam-leads. The diode is formed on the top of the
pedestal, and air-bridges connect the diode to the
beam-leads. The topside is fully encapsulated with
silicon nitride and also has an additional polymer
layer for scratch and impact protection. These
protective coatings prevent damage to the diode
junction and air-bridge during handling and
assembly. The diodes exhibit low series resistance,
low capacitance, and extremely fast switching speed.
Applications
The ultra low capacitance, low RC product and low
profile of the MA4PBL027 makes it an ideal choice
for use in microwave and millimeter wave switch
designs, where low insertion loss and high isolation
are required. The low bias levels of 10 mA in the low
loss state and 0 V in the isolation state allows the
use of a simple 5 V TTL gate driver. These diodes
can be used as switching arrays on radar systems,
high speed ECM circuits, optical switching networks,
instrumentation, and other wideband multi-throw
switch assemblies.
