Description
This device is a silicon, glass PIN diode surmount
chip fabricated with MACOMs’ patented HMIC^™
process. This device features two silicon pedestals
embedded in a low loss, low dispersion 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
electrically conductive. Selective backside
metallization is applied producing a surface mount
device. This vertical topology provides for
exceptional heat transfer. The topside is fully
encapsulated with silicon nitride and has an
additional polymer layer for scratch and impact
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
moderate incident power applications, ≤10 W/CW or
where the peak power is ≤52 W, pulse width is
≤1 μs, and duty cycle is ≤0.01%. Their low parasitic
inductance, 0.4 nH, and excellent RC constant,
make these devices a superior choice for higher
frequency switch elements when compared to their
plastic package counterparts.
