Description
This device is a silicon-glass PIN diode chip fabricated
with M/A-COM Technology Solutions patented HMIC
process. This device features two silicon pedestals em-
bedded 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 addi-
tional polymer layer for scratch protection. These pro-
tective 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 ( 5 W C.W. ) or Higher Incident
Peak Power ( 200 W, 1 uS, 0.001 Duty ) Series, Shunt, or
Series-Shunt Switches. Small Parasitic Inductance, 0.7
nH, and Excellent RC Constant, 0.20 pS, make the de-
vices ideal for TR Switch and Accessory Switch Circuits,
where higher P1db and IP3 values are required.
These diodes can also be used in
π,
T, Tapered Resis-
tance, and Switched-Pad Attenuator Control Circuits for
50Ω or 75Ω systems
