Techniques for ultra wide stopband IF filters

Often, significant filtering requirements exist for planar and drop-in receiver filters at IF frequencies in the 1 to 4 GHz frequency range of typically 3 to 7x fIF (centre frequency) to comply with spurious emission requirements and suppression of spurious outputs.

Compact tunable IF filters

Bandwidth, frequency and power reconfigurable payload architectures are currently under development by major satellite manufacturers. Today's fixed bandwidth filters are a major bottleneck in such systems and have led to the implementation of reconfigurable filters. These new reconfiguration scenarios require flexible converters and, hence, flexible filters to be accommodated after the down/up conversion

Circular Polarisation Dual-Optics Proof-of-Concept

Proof of Concept 3

 

 

 

 

 

Several dual-optics antenna architectures with polarisation sensitive screens in linear polarisation (LP) have been developed and the concept has been proven to perform well in LP. 

Dual-band polarising reflectors for multiple beam applications

Parabolic reflector antennas are widely used in satellite communications, tracking radars, as well as other similar applications.

Nonlinear analysis of RF signals for end-to-end communication system performance prediction

Increasingly complex coding and modulation schemes are being applied as means to enhance spectral efficiency. Coupled with the requirement for low-cost and environmentally friendly communications, the aspect of signal amplification becomes entangled with the actual spectral content of the system.
