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.

The K-Band Luminosity Function
Symposium - International Astronomical Union, 1996Investigations of broad band energy distributions of specific classes of sources requires homogeneous samples of a sufficiently large number of objects. Deep and homogeneous surveys in those energy ranges which are accessible to satellites only are rare. One such a field in the north ecliptic pole (NEP).

K-band Transferred Electron Oscillator
IETE Journal of Research, 1976Transferred electron oscillator developed in K-band (18–26.5 GHz) is reported. Frequency and power characteristics of the oscillator are presented. It is observed that a mechanical frequency tunability of nearly 5 GHz with a minimum output power of 10 mW is obtained.

Microelectromechanical K-Band Switching Circuits
1999 29th European Microwave Conference, 1999Two single-pole single-throw (SPST) K-band circuit designs incorporating low-loss microelectromechanical systems (MEMS) microwave shunt switches are reported. DC measurements indicate actuation voltages in the order of 20 V with an on-to-off capacitance ratio of 30.

An additive manufactured K-Band Waveguide Coupler and K-Band Antennas in SLM-Technology
2020 23rd International Microwave and Radar Conference (MIKON), 20203D printing offers a very innovative opportunity for creating cheap or special rf-components like waveguides, couplers or antennas. However, these components require electrical conductive materials to be built of. Therefore, selective laser melting of metal powder is also an attractive production technology.

K band Gaussian beam oscillator
1994 24th European Microwave Conference, 1994A K band Gaussian beam oscillator, with a new quasi-optical resonator, is described. The resonator consists of a plane mirror substrate and a concave spherical mirror with a highly reflective, partially transparent region. A high Q factor, obtained by using this spherical mirror, results in a low phase noise of the oscillator and the output power is ...

Micromechanical electrostatic K-band switches
1998 IEEE MTT-S International Microwave Symposium Digest (Cat. No.98CH36192), 2002Two novel designs of micromechanical capacitive switches using serpentine and cantilever springs for low actuation voltage applications are reported. Both designs also incorporate an electrode situated above the switching structure in order to provide system stability.

K-band slot reflectarray antennas
2018 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus), 2018The paper studies metal-only slot reflectarray antennas characteristics. All arrays under study are designed to be manufactured with laser-cutting technique. Bandwidth dependence on geometry parameters is considered for the case of single-layer linear-polarization antenna. The analysis is based on both full-wave simulation and a solution of an integral-

The K-Band Luminosity Function of Galaxies
Symposium - International Astronomical Union, 1997The luminosity function of galaxies is central to many problems in cosmology, including the interpretation of faint number counts. The near-infrared provides several advantages over the optical for statistical studies of galaxies, including smooth and well-understood K-corrections and expected luminosity evolution. The K–band is dominated by near-solar
