Gunn Diodes
-
The Gunn diode is the best known and most readily available device in the family of transferred electron devices (TED). They are employed as DC to microwave converters using the negative resistance characteristics of bulk Gallium Arsenide (GaAs) and only require a standard, low impedance, constant voltage power supply, thereby eliminating complex circuitry. Teledyne Lincoln Microwave’s DC1200 series of GaAs Gunn diodes is designed for operation at fixed frequency (determined by the oscillator cavity) within a specified band under CW or pulsed conditions.

Current Pulsers and Laser Diode Drivers (Pulsed Current)
-
These instruments generate current pulses whose amplitude is largely independent of the load voltage. This makes them ideal for pulsing device whose voltage may vary with time (for instance, the voltage drop of laser diodes may vary with temperature, or explosive squibs which change impedance during ignition). This voltage independence is a trade-off with speed. If faster rise times are required, consider using pulsed voltage instruments instead.
