Tender Details

Tenders are invited for KA-Band Radio Frequency Front End Resistant to Intentional Interference for Secure TTC (Artes 4.0 4s Spl 4g.041)

Price Range
500 KEURO

Description: TTC is a key equipment for all satellites since it provides the umbilical cord to the control station(s). It has to operate in an RF environment that tends to become more and more congested and interference prone, whether intentionally or non-intentionally. For secure communications such as government satellites, techniques like spread spectrum and CDMA (Code Division Mulitplexing Access) etc., may help but on the condition that the RF receiver front-end still operates in a linear regime. Operation in linear regime means that signal is not distorted and decoding is possible as it should meet minimum required Signal to Noise ratio. For secure communications, increasing linear power dynamic range by 20 dB will allow decoding of CDMA and spread sprectum signals.

Therefore, by moving from GaAs (Gallium Arsenide) to GaN (Gallium Nitride) technology, such rugged Ka-band RF front ends are possible which can operate under intentional or unintentional radio frequency interference. Recent developments have proven that GaN technology can provide a much improved linearity as well as higher power handling as compared to more traditional GaAs technology used in all current TTC implementation
