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

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.
