Description
Alpha’s product line of silicon chip and packaged PIN
diodes are designed to cover a wide variety of
microwave and RF applications. The PIN designs have
been designated and characterized for fast speed
switches, low distortion attenuators and high RF
voltage applications. Alpha’s PIN semiconductor
materials and processing technology allows for a
superior combination of Rs, capacitance and voltage
ratings.
The packaged PIN diodes were selected as the most
commonly employed PIN diode chip designs in
standard packages. These designs are adaptable to
many RF and microwave requirements that utilize
packaged PIN diode components and are available
for quick delivery. All ceramic packaged PIN diodes
are hermetically sealed.
This product line of PIN diodes are designed to be
capable of meeting electrical and environmental
screening requirements of military and space
applications.
The PIN diode chip offering is specified for electrical
and physical parameters allowing designers of hybrid
circuits to be assured of consistent microwave and
geometric properties. All high voltage designs
incorporate glass passivation resulting in a reliable
low leakage current device.
