Patent ID: 7403076

Claim:
A high frequency quasi optical oscillator power source comprising: a) an array of amplifier devices each comprising: (i) an input antenna tuned to receive an input signal at a fundamental frequency; (ii) a power amplifier coupled to the input antenna capable of amplifying a signal at the fundamental frequency; (iii) a frequency multiplier capable of providing signals at a multiple of the fundamental frequency and at the fundamental frequency coupled to the power amplifier; and (iv) an output antenna coupled to the frequency multiplier and tuned to radiate signals at the fundamental frequency and at the multiple of the fundamental frequency; b) a grating lobe-to-main lobe converter located above the array of amplifier devices, the grating lobe-to-main lobe converter being adapted to convert grating lobe power to main lobe power at the multiple of the fundamental frequency; and c) a frequency selective reflector opposing the array of amplifier devices, the frequency selective reflector being adapted to reflect signals at the fundamental frequency and to pass signals at the multiple of the fundamental frequency.
