Description

ELVA-1 injection-locked IMPATT Amplifiers IILA series are intended for high power amplification of CW and Pulse mm-wave signals. They are offered in the frequency range of 26-150 GHz in five wave-guide sizes. They can operate from power level as low as 2-3 mW, which can be obtained directly from Up Converter or Frequency Multiplier. When Amplifier is injection-locked, FM noise of the output is the same as the injection signal. In the absence of an in-band input signal of sufficient power to attain injection-lock, there is a free running output signal.

The amplifiers are provided with integral circulators and DC voltage regulator. An optional heater is available for better temperature stability. To achieve higher gain, broader locking bandwidth and higher output, multi-stage and multi-diode configurations are also available.

How to Order
