OPTISKT SYNKRONISERAD MIKROVAGSOSCILLATOR

摘要

A microwave oscillator (14 Figure 1) is used to modulate a laser diode (12) and the resultant modulated light output energy from the laser diode is applied through an optical fibre waveguide (32) to the active solid state device (26) in a microwave oscillator circuit (28) such that the output signal from the microwave oscillator is phase locked to the modulation carried by the light energy. "On-off" switching of the microwave oscillator can be controlled simultaneously with phase locking. The solid state device 26 can be an Impatt diode, Gunn device, field effect transistor or silican transistor (Figure 4).
