Description

The MA4SPS552 is a silicon-glass PIN diode chip

fabricated with MACOM’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

metallization 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 (5 W CW) or higher

incident peak power (200 W, 1 µs, 0.001 Duty)

series, shunt, or series-shunt switches. Small

parasitic inductance, 0.7 nH, and excellent RC

constant (0.20 ps) make the devices 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

Resistance, and Switched-Pad Attenuator Control

Circuits for 50 Ω or 75 Ω systems.
