Description

Fhe MA45200 series of silicon abrupt junction tuning

iaractors has been designed to obtain the highest Q

~ossible.Each- device in this series has a high density

silicon dioxide passivation which results in exceptionally

ow leakage currents and low post tuning drift. These

silicon abrupt junction tuning varactors, which have a high

Q, also exhibit large capacitance changes with bias

oltages. The capacitance change is approximately equal

to the square root of the voltage. The MA45200 series

diodes are available in a number of ceramic packages as

well as in chip form.

Applications

The MA45200 series of silicon tuning diodes is ideally

suited for frequency tuning applications through Ku band.

These devices are designed for use in solid state elec-

tronic tuning of transistor, Gunn and IMPATT oscillators.
