Ka Band power limiter for satellite channel amplifier

Some Ka-Band payloads request an anti-jamming capacity to be protected against RF interference attacks. This performance can be provided by Thales Alenia Space Ka-Band channel amplifiers thanks to the new Ka-band hard limiter. The power limiter presented in this paper allows to perform this limitation over a 10 dB power dynamic range in the frequency band 20.2 - 20.9 GHz providing in addition tuning capabilities and taking into account the design de-rating rules mandatory for space application.
