Abstract :
A monolithic load comparison twist reflector (LSTR) has been built and tested for use in 94 GHz passive imaging cameras. Radiometric and quasioptical tests show that the array has an insertion loss of 0.25 dB. This active array of PIN diodes replaces the mechanical choppers often used in load comparison.
