Abstract

The experimental behaviour of an optically triggered TRAPATT diode amplifier is described. An optical signal, modulated at microwave frequencies, stimulates the TRAPATT process, whereby the light signal is directly transformed into an amplified microwave signal. Power gain, defined as the ratio of generated microwave power to the locking light power, efficiency, and frequency range have been measured and compared with the data obtained from the same diode operating in a conventional TRAPATT amplifier.
