Description
This device is a silicon-glass PIN diode chip 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
sidewalls 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 packageless devices are suitable for usage in moderate
incident power (10 W C.W.) or higher incident peak power
(500 W) series, shunt, or series-shunt switches. Small parasitic
inductance, 0.35 nH, and excellent RC time constant, 0.22 pS,
make the devices ideal for wireless TR switch and accessory
switch circuits, where higher P1dB and IP3 values are required.
These diodes can also be used in π, T, tapered resistance, and
switched-pad attenuator control circuits for 50Ω or 75Ω
systems.
