Description
M/A-COM’s MA4SPS402 is a silicon-glass PIN diode
fabricated with M/A-COM’s patented HMIC™ process. This
device features two silicon pedestals embedded in a low loss
glass. The diode is formed on the top of one pedestal and
connections to the backside of the device are facilitated by
making the pedestal side walls conductive. Selective backside
metalization is applied producing a surface mount device. The
topside is fully encapsulated with silicon nitride and has an
additional polymer layer for scratch protection. These
protective coatings prevent damage to the junction and the
anode air-bridge during handling and assembly.
Applications
These devices can be used in series and shunt switches up to 20
GHz where smaller area and profile are required. Low parasitic
values of L and C make additional circuit tuning unnecessary.
These diodes can also be used for switched pad attenuator
circuits.
