Microwave Power Leveler for K Band
Review of Scientific Instruments, 1964A device has been developed for regulating milliwatts of microwave power in the 24-kMc region. The power leveler has been shown to operate over the electronic sweep range of a K-band reflex klystron, and to regulate power to within ±0.5%.

K-band adjustable noise generators
Instruments and Experimental Techniques, 2012K-band (18–37 GHz) adjustable noise generators based on waveguide matched loads are presented. The physical temperature of the load absorber is maintained at a specified level with accuracy no more than ±0.007 K by a digital multichannel temperature-stabilized system.

Abstract : An echo line is a long waveguide in which the radar pulse re-echoes producing a series of pulses on the indicator for test purposes. The fabrication and testing of an 18inch helix of an oversized K-band waveguide 150 ft long are discussed. Tests showed the attenuation to be 0.029 dh/foot, which suggests the use of such oversized waveguide ...

Silicon micromachined K-band filters
2012 International Conference on Computing, Electronics and Electrical Technologies (ICCEET), 2012This paper describes a substrate integrated waveguide (SIW) based filter at K band frequency on silicon substrate. TMAH etching is used to form the via-holes for SIW cavities. Simulations and comparison of TMAH and Deep reactive ion etching (DRIE) etched cavity has been presented.

MTT-S International Microwave Symposium Digest, 2005
This paper will report on the structure and performance of GaAs FETs developed for K-band applications. A power output of 27dBm was obtained with 5dB gain at 21GHz. A novel low loss waveguide to microstrip transition was used in the measurement. Its design will be described.

K-Band Waveguide Bragg Structures
2006 16th International Crimean Microwave and Telecommunication Technology, 2006The possibility for controlling band-gap parameters of Bragg structure at variation of its period has been shown. Periodic dielectric structures have been proposed to be used as waveguide filters of mm, sub-mm and THz ranges with different frequency characteristics.
