The History of Prescient Wireless, Incorporated
Prescient Wireless was formed in June of 2006 by a team of engineers seeking to put their many years of engineering experience in the development of cellular base stations for a major original equipment manufacturer (OEM) to use on a broader scale. Our first product was the world’s first 4G WiMAX, IEEE 802.16e compliant cellular base station product that was well received by the communications market. Our customers included several cellular OEMs, a test equipment manufacturer as well as the major WiMAX chip supplier.
Beginning in 2007, Prescient Wireless developed a high performance Doherty power amplifier for a device supplier utilizing GaN (gallium nitride) power devices. Since then, Prescient Wireless has developed a wide variety of Doherty power amplifiers for the cellular base station market. This includes amplifiers that utilize both LDMOS (laterally diffused metal oxide semiconductor) and GaN (gallium nitride) power devices. We have gone on to develop power amplifiers and low noise amplifiers for both device suppliers as well as cellular base station OEMs. Prescient Wireless continues to this day to develop solid state Doherty amplifiers and low noise amplifiers for multiple clients on a regular basis.
In 2007, Prescient Wireless expanded into the avionics market developing a radio transceiver for an airborne application that included the transponder, distance measuring equipment (DME) and traffic collision avoidance system (TCAS) functions. Our engineering team was able to utilize their extensive background in high volume, state of the art radio transceiver design to develop a radio design that was very highly integrated, compact with low weight and low power that pushed the envelope for avionics equipment design.
In 2008, Prescient Wireless developed an extremely high performance direct sampled receiver for the military market. The receiver utilized state of the art analog to digital converters (ADCs) and track and hold amplifiers to directly convert the 2-4GHz band directly to baseband data. This project enabled a major defense contractor to demonstrate system performance in a sea trial to the US military and consequently win a multimillion dollar government contract.
In 2009, Prescient Wireless was contracted to develop a power amplifier for the medical market. Operating at 2450MHz, the amplifier delivered 140 Watts of RF power for a microwave ablation system with high reliability. Prescient Wireless has since developed other RF subsystems for the same system and continues today to manufacture and supply these RF subsystems to our client.
Throughout 2010 and 2011, Prescient Wireless developed a number of highly advanced ground radar systems. This included a 1000W EIRP transmitter operating in the 2.7 to 2.9GHz band that is capable of precisely timing transmissions to within a few nanoseconds of a system clock. Also developed by Prescient Wireless was a multiband, 978MHz (UAT), 1030MHz and 1090MHz receiver that is capable of generating precise time stamps for the time of arrival (TOA) of received messages.
Beginning in 2011, Prescient Wireless began the development of several test and measurement and industrial products. The first of these was a handheld test and measurement device that required a high performance but very low cost, wide bandwidth transmitter and receiver. The device operated from 10MHz to 1GHz and measured such parameters as insertion loss, return loss and isolation of a multiconductor cable. Prescient Wireless also developed an RFID product that involved antenna design as well as low cost RF switching. Another product developed during this time period was an ultracapacitor based industrial power backup system.
In 2013, Prescient Wireless developed all of the hardware for a large scale industrial sensor system. This project required tens of thousands of highly sensitive detectors that could time stamp detection events with an accuracy of a few nanoseconds relative to a system clock. The design included a high voltage power supply, a very low noise current detector along with a FPGA board with an embedded controller.
In 2014 and 2015, Prescient Wireless was contracted by a major cellular base station manufacture to develop Doherty power amplifiers and low noise amplifiers for their latest microcells. Prescient Wireless engineers were also involved in the CPLD and FPGA design that included baseband processing, CPRI link, RSSI processing and control for the cellular base station. During this period, Prescient Wireless was also contracted to develop a low cost, high quality wireless audio system to be used in a restaurant application.
Prescient Wireless continues to expand into new areas of electronics design, utilizing the engineering team’s extensive background in multiple disciplines to provide state of the art products for our clients.
