Ultra-stable beacon source for laboratory testing of optical trackingThe ultra-stable beacon source (USBS) provides a laser-beam output with a very low angular jitter and can be used as an absolute angular reference to simulate a beacon in the laboratory....
Waveguide multimode directional coupler for harvesting harmonic power from the output of traveling-wave tube amplifiers... Test results from proof-of-concept demonstrations are presented for Ku/Ka-band and Ka/E-band MDCs, which demonstrate sufficient power in the 2nd harmonic for a space borne beacon source for mm-wave atmospheric propagation studies
A novel multimode waveguide coupler for accurate power measurement of traveling wave tube harmonic frequencies... In addition to accurate power measurements at harmonic frequencies, a potential application of the MDC is in the design of a beacon source for atmospheric propagation studies at millimeter-wave frequencies
Traveling-wave tube amplifier second harmonic as millimeter-wave beacon source for atmospheric propagation studiesThis paper presents the design and test results of a CW millimeter-wave satellite beacon source, based on the second harmonic from a traveling-wave tube amplifier and utilizes a novel waveguide multimode directional coupler....
