RF Interference Cancellers
LArge Signal CANceller (LASCAN™)
and INchip™ RF Interference Mitigation
Signal Subtractor and Canceller (LASCAN™)
significantly reduces unwanted RF interference in
system using the electromagnetic spectrum.
Such systems often needs to maintain
operation in the face of large interfering signals
that can be as much as 100 dB stronger than the
signal of interest (SOI) that the equipment needs to receive. When connected between
the antenna and the systems transmit and receive
paths, LASSCAN™ had demonstrated 60-70 dB of
large interference signal cancellation.
LASSCAN™ is applicable
to systems that operates in
any RF band; to date LASSCAN™ has been demonstrated to operate
in frequency bands between the low end of HF (3
MHz) and the high end of X-band (12 GHz);
operation is possible as high as W-band (100 GHz).
LASSCAN is also capable of mitigating
forms of co-spectrum interference: co-site
(desired and interfering signal spectra do
not overlap); co-channel (desired and interfering signal spectra
overlap) and co-angle (desired and interfering
signals come from the same direction).
PSI has provided RF
interference cancellers handling 50 Watts of power
in rack based packaging and developed lower power,
much smaller size hybrid IC versions called INchip™.
