Ka-band Integrated Transmitter for SATCOM
2020 27th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2020This paper presents a direct conversion transmitter integrated circuit (IC) implemented in 0.13um SiGe BiCMOS, targeting Ka-band satellite communications. The IC is comprised of an active IQ baseband filter with adjustable cutoff frequency 90 - 720MHz, IQ up-converter with gain control and local oscillator (LO) leakage compensation, LO generation ...

In the frame of the “Study into Ka-band SAR”, a project funded by the European Space Agency (ESA), the authors investigated new instrument concepts to implement a spaceborne high resolution interferometric SAR operating at Ka-band. In particular, thanks to the antenna separation which is required at these frequencies to achieve accurate height ...

The regulatory status of the Ka-band
International Journal of Satellite Communications, 1999Access to frequencies is a major concern for all satellite systems. Even if the Ka-band is currently lightly used by Satellite Systems, the Regulatory rules which will govern its access to planned new Satellite Communication Systems have started to be changed during the last World Radiocommunication Conferences.
