Description and Applications
This device is a silicon-glass PIN diode chip fabri-
cated with M/A-COM Technology Solutions patented
HMICTM 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 back-
side 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.
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 an excellent RC time constant, 0.22 pS, make
these devices ideal for switch applications where
higher P1dB and IP3 values are required. These
diodes can also be used in p, T, tapered resistance,
and switched-pad attenuator control circuits for 50W
or 75W systems.
