RF Over Fiber Links
RF/Microwave
signal connectivity using fiber-optic cable
provides a low loss, EMI and RFI immune, light
weight, secure, and high reliability solution in
place of coaxial cable or free-space
transmission. PSI’s engineering team are among
the principal contributors that established the
field of microwave and RF photonics technology
setting numerous record breaking performance
results along the way. Today, PSI offers a
variety of standard and customized RF,
microwave, and millimeter-wave over fiber
links to >110 GHz including the lowest noise (NF) figure
links available without requiring a low noise
amplifier (LNA).

Simultaneous Transmit
and Receive (STAR)
Every wireless device requires electromagnetic
spectrum, a finite natural resource that is
controlled by government regulations throughout
the world. Many billions of dollars are spent by
wireless services providers for spectrum licenses
but the demand for more economically usable
spectrum to satisfy the rapid growth in wireless
applications cannot be satisfied. To help solve
the spectrum crisis, PSI has invented same-channel
simultaneous transmit and receive (STAR) circuit
and software algorithms that effectively doubles
spectrum efficiency.

RF Interferfence Cancellers
Although regulated, the
electromagnetic spectrum is a congested
environment with multiple radios operating near
each other resulting in co-site RF interference.
Whether unintentional or intentional (jamming),
in-band RF interference that cannot be reduced by
filters degrades or can completely interrupt
system connectivity. PSI has developed unique
circuit and software algorithm solutions to
dramatically reduce unwanted RF interference from
an interferer on the same platform or on a
separate platform where a reference copy of the
interferer is not available.

Photonically Sampled Electronically Quantized
(PSEQ) ADC
Analog to
digital converters (ADCs) provide the critical
link between the RF analog front-end and the
high speed digital signal processing function
chain in a receiver. Unfortunately in high
performance applications, the ADC is typically
the weakest link in this chain; limiting the
capabilities of the digital receiver. The
photonically sampled electronically quantized
(PSEQ) ADCs in development at PSI provides >10x
improvement in ADC speed and resolution enabling
new system capabilities and improved accuracy. |
