Description
M/A-COM Technology Solutions KILOVOLT™ PIN
diode series utilize modern semiconductor 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 PIN 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 material
onto which P+ and N+ regions are deposited using an
epitaxial process designed by M/A-COM Technology
Solutions for high voltage PIN diodes. This process
results in better preservation of the carrier lifetime and
superior layer to layer interface when compared to a
conventional double diffused process. The processing
of the I-region width is tightly controlled using modern
lapping techniques. KILOVOLT™ PIN diode chips
utilize M/A-COM Technology Solutions proprietary
Cermachip™ glass passivation. The hard glass covers
all exposed junction and intrinsic surfaces. This results
in a hermetically sealed, passivated chip that has been
used in many high reliability military and commercial
programs.
Packaging
The metal-ceramic packages were developed
specifically for the KILOVOLT™ PIN diode series.
The packages are designed to withstand extremely
high voltages and currents. The packages meet the
environmental requirements 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 exceeding 300°C. The anode strap
has a unique, large cross-sectional area allowing
for high current carrying capability. The packages
are sealed using a projection welding technique in
an inert environment. KILOVOLT™ PIN diodes are
available with a solder lug on the anode electrode
to allow for a convenient and reliable wrap-around
Applications
The KILOVOLT™ PIN diode series is 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 performance. Some
typical applications are as follows:
 Filter Switches
 Antenna Couplers
 Power Amplifier By-pass Switches
 MRI Switches
