Microwave Diode and Capacitors - Cobham plc

Tuning Varactor Diodes
Ceramic Packaged Silicon Tuning Varactor Diodes
The ML4300 Series of silicon microwave tuning varactor diodes has been designed to obtain the highest Q
possible. Each device in this series has a high density silicon dioxide passivation, which results in exceptionally
low leakage currents and low post tuning drift.
This series is ideally suited for frequency tuning applications up to 20 GHz. These devices are designed for use
in solid state electronic tuning of transistor, Gunn and IMPATT oscillators. They may also be used in tunable
filters, phase shifters up and down converters and low order multipliers.
