RFEL
personnel also have extensive experience in the optimal implementation
of multi-channel digital receiver front ends for applications in
communication systems.
Our system design expertise and library of unique IP cores allow
us to provide front end filtering subsystems for high performance
requirements. Use of multiple digital down converters in ASICs or
FPGAs are common solutions but require large amounts of silicon
and consume large amounts of power. RFELs unique tuneable filter
banks offer a more compact and power efficient implementation.
RFELs extremely high speed processing capability often enables a
much greater bandwidth containing a multitude of signals to be down
converted and filtered into individual channels, and can also provide
multi resolution signal monitoring where required by the application.
For evenly spaced channels, our off the shelf Polyphase DFT implementations
are extremely effective at signal conditioning. The Polyphase DFT
filters can be tailored for filter shape and adjacent channel rejection
and can be maximised for optimum system performance. For designs
where irregular or re-configurable channelisation is required, the
Pipelined Frequency Transform (PFT) or Tuneable PFT designs are
often the most relevant.
RFEL can provide a complete front-end subsystem solution including,
for example, down conversion, filtering, rate conversion and carrier
recovery. Typical receiver and transmitter system designs are shown
below, showing the type of design issues that the company has experience
with.
Typical Applications include:
Satellite communications, Wireless communications, Defence communications.
RFEL is actively engaged in subsystem design for a variety of customer
requirements and are available for free, no obligation, initial
concept discussions.
