Optically controlled K-band oscillator
IEEE International Digest on Microwave Symposium, 2002PIN photodiodes play an important role in detection of modulated light in fiberoptic links, however, these devices are essentially junction devices, with bias-dependent capacitance very similar to those of varactor diodes. Particularly under proper biasing conditions, junction capacitance of these devices can be changed by light illumination.

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.

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.

K-Band BARITT Doppler Detectors
MTT-S International Microwave Symposium Digest, 2005The properties of K-band BARITT devices for use as self-mixing doppler detectors have been studied experimentally and with a simplified computer model. The computer results predict sensitive BARITT doppler operation even at low power levels. The experimental results show that the BARITT is superior to both IMPATT and Gunn devices for use as self ...

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.

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.
