Advanced satellite communication systems should be capable of preventing unauthorized access or exploitation of communication services by adversaries. This can be achieved by use of wideband multi-channel digital transceivers which employ channelizer to extract the channel of interest from digitized RF bands for further baseband processing. Various anti-jamming techniques like Frequency hopping are used to prevent the systems from intentional jamming by the hostile systems. This paper presents an efficient channelizer architecture which supports wideband as well as narrowband channels with programmable channel bandwidth followed by frequency hopping for the proposed SATCOM system. The target design is a flexible channelization unit which divides the incoming data links of 11 MHz bandwidth into two data links in granularity of 0.5 MHz depending upon user requirements.
