PSI to Present at GOMAC Tech (March 31 –April 4th)

Dr. Charles Cox will present a paper titled " Broadband Full-duplex Operation of Antenna Systems Using Analog Photonic Remoting Links with Low Noise Figure" at the GOMAC Tech 2014 held from March 31 - April 4, 2014 in Charleston, SC.  Learn more about the 39th annual GOMAC Tech conference here. The paper will report achieving a noise figure of 5.7 dB at 12 GHz in an amplifierless photonic receive link. This result enables a new transmit/receive interface called TIPRX (Tx-Isolating Photonic Rx) that isolates the transmit and receive signal paths by > 40 dB over > 3 decades of bandwidth, allowing an antenna to receive small signals while simultaneously transmitting high-power signals

PSI Discusses Simultaneous Transmit and Receive (STAR) at IEEE Meeting

Sponsored by the IEEE Microwave Theory & Techniques, Photonics and Aerospace and Electronics Systems Societies, PSI presented a discussion on STAR technology at a meeting held at MIT Lincoln Lab. The presentation and demonstartion described some of PSI's groundbreaking work enabling simultaneous transmit and receive (STAR) using the same RF frequency in a single aperture antenna system. Simultaneous transmit and receive: a new capability to increase the utilization of the RF spectrum and improve the efficiency of systems that use the spectrum.

PSI Introduces Mini QUAD+ Modulator Bias Controller (PSI-2011-11)

PSI announces the availability of a new mini optical modulator bias controller (MBC) providing comprehensive control of external optical modulators from a single, small form factor circuit board. The PSI-2011-11 provides automatic tracking of Quad+ bias point. Using a standard dither tone set at 1 KHz, the PSI-2011-11 tracks the operating point to within +/- 1 at 1% dither of Vπ when operating at quadrature. The dither tone amplitude is factory set to 1% of customer specified nominal Vπ. A high degree of bias point accuracy is maintained over a wide operating temperature range of –20C to +70C. Using a common photodetector, the bias point accuracy is easily maintained over a >10dB range of optical power. The PSI-2011-11 can be plugged into a motherboard or connections can be made though discrete wiring to the appropriate input/output connector pins. Further information, including a product datasheet can be found here.

PSI Introduces Power Ratio Bias Controller (PSI-0404-11)

PSI announces the availability of a new optical power ratio bias controller circuit card. The PSI-0404-11 modulator bias controller offers a simple solution for precise control of electro-optical modulators. This controller accurately prevents
bias point drift from any user defined point on the Mach-Zehnder
transmission voltage curve by holding a fixed power ratio of the optical input
and output of the modulator under control. Through the use of integrated
optical tap coupler/power monitor devices, the PSI-0404-11 monitors the
ratio of DC optical power level at the modulator’s input and output ports.
Precise feedback control circuitry maintains a user-set ratio through automatic
adjustment of the bias voltage applied to the modulator under control. Further information, including a product datasheet can be found here.

PSI Introduces New Cost Effective 20 GHz Link

PSI announces the availability of a new cost effective broadband RF over fiber link that provides excellent RF performance at a cost effective price. The PSI-1600-20L link series incorporates and RF to optical transmitter module along with an optical to RF receiver module for the transmission of RF signals from 50 MHz to beyond 20 GHz over singlemode fiber optic cable. Further information, including a product datasheet can be found here. Please contact PSI about application specific performance needs for this product.
