Abstract :
The use of an IMPATT reflection amplifier to produce phase modulation at microwave frequencies has been demonstrated. By operating the IMPATT diode near to avalanche resonance frequency, phase-switching through 180° can be obtained, and the drive current can be set to give equal gain in the two phase states so that no amplitude modulation is produced. Possible application to high-frequency data-transmission systems is envisaged.
