Full-Duplex Radio Solutions
Transmit and Receive (STAR) RF Front-ends
PSI has invented and developed RF front-end
circuits that enable dramatic advances in spectrum
efficiency by allowing radios to communicate
simultaneously on the same frequency. This
technology effectively doubles the capacity of any
wireless communication network and will help
alleviate the mounting available spectrum crisis.
Using a combination of unique circuit techniques,
PSI's front-end solutions actively suppress the
large self-interfering transmit signal while
preserving the much weaker remote received signal.
Since the first demonstration system in 2008, PSI
has developed and delivered single-frequency
full-duplex enabling front-end products for a
variety of applications in different frequency
bands. Product solutions have been either RF-in to
RF-out (all analog) such as our
PSI-8650 STARbox™ developer’s front-end providing up 70
dB of transmit-to-receive (T/R) isolation or RF-in
to digital-out front-end sub-systems providing
>100 dB of T/R isolation.
For applications requirng smaller packaging
opions, PSI now offers engineerring protoypes of
the PSI-8611-001G STARchip™Products using only electronic circuit
technology or a combination of electronic circuit
and photonic technology have been provided, For
applications requiring smaller packaging options,
PSI now offer engineering prototypes of the
