Description

M/A-COM’s Kilovolt PIN diodes utilize modern semi-

conductor and packaging technology that assures

low loss, low distortion, and reliable performance in

multi-kilowatt switch applications at frequencies as

low as 1 MHz. The semiconductor chips employed

have low resistance, high power dissipation and very

high stand-off voltage capability. Kilovolt PIN diodes

employ ultra high resistively, long carrier lifetime,

float zone silicon intrinsic material onto which P+ and

N+ regions are deposited using an epitaxial process

specifically designed at M/A-COM for high voltage

PIN diodes. This process results in better preserva-

tion of the intrinsic carrier lifetime and superior junc-

tions in comparison to the conventional double dif-

fused process. The processing of the I-region width

is tightly controlled using modern lapping tech-

niques. Kilovolt PIN diode chips utilize M/A-COM’s

proprietary cermachip glass passivation. The hard

glass covers all exposed junction and intrinsic region

surfaces. This results in a hermetically sealed, pas-

sivated chip that has been accepted in many hi-rel

military programs.

Applications

M/A-COM’s Kilovolt PIN diodes are designed for use

as high power switching elements in multi-kilowatt

HF and VHF applications. These PIN diodes have

been extensively characterized for their electrical

and thermal properties to assure predictable low

loss, high power handling, and low distortion per-

formance. Some typical applications are as follows:

♦ Filter Switches

♦ Antenna Couplers

♦ Power Amplifier By-pass Switches

♦ MRI Switches

Package Outlines

Applications

The metal-ceramic packages were developed spe-

cifically for the Kilovolt PIN diode series. The pack-

ages are designed to withstand extremely high volt-

ages and currents and to be compatible with indus-

try standard semiconductor chip and RF circuitry.

These packages meet the environmental require-

ments of MIL-STD-202 and MIL-STD750. The PIN

diode chip is bonded to the package and the anode

strap is bonded to the chip at temperatures ex-

ceeding 300°C. The anode strap has a unique,

large cross-sectional area design allowing for high

current capability. The packages are sealed using

a projection welding technique in an inert environ-

ment. Kilovolt PIN diodes are available with a sol-

der lug on the anode electrode to allow for a con-

venient and reliable wrap-around wire connection.
