A wideband X100 low noise microwave frequency multiplier
Abstract
A low-noise X100 frequency multiplier chain has been built for use in an airborne radar exciter/downconverter assembly. The input frequency band is 91-94 MHz, and the output frequency band is 9100-9400 MHz. The integrated downconverter assembly includes: dual receiver channels made from low-noise GaAs FETs; X-band preamplification; intermediate frequency filtering; and amplification. The entire assembly is packaged for installation in combat aircraft and occupies less than 135 cubic inches. The phase noise spectral density of the X100 multiplier is given for various frequencies in the range 1 MHz-100 Hz. Black and white photographs of the exciter downconverter assembly are provided.
