Frequency modulation of IMPATT diodes by optical illumination
Abstract
X-band IMPATT diodes are frequency modulated by optical illumination. The light is coupled through a standard optical fibre to the diode oscillating in a waveguide resonant circuit. Direct modulation of a semiconductor laser is used for the frequency modulation. A maximum modulation frequency of 2.5 MHz can be obtained.
