Title: Christopher D Broughton: Innovator in Radio Receiver Technology
Introduction
Christopher D Broughton is a notable inventor based in Mesa, AZ (US). He has made significant contributions to the field of radio receiver technology, holding a total of 6 patents. His work focuses on enhancing the performance and functionality of radio receivers, making them more efficient and effective in various applications.
Latest Patents
One of Broughton's latest patents is the Nearly DC IF Phase Locked Transceiver. This innovative receiver converts the RF carrier to a very low frequency and incorporates a PLL demodulator, allowing the IF to be AC coupled. The PLL demodulator is designed without IF filters and has a bandwidth wide enough to demodulate FM signals. Additionally, the components of the receiver can be switched to a transmission mode capable of FM or PSK modulation with a simple circuit. The receiver also features an AM or PSK coherent amplitude detector, which has been modified into an imageless spectrum analyzer.
Another significant patent is the Receiver Interference Suppression System. This radio receiver circuit effectively suppresses an interfering signal that exhibits an amplitude significantly greater than that of a desired signal and a frequency nearly the same as that of the desired signal. The received signal is processed through a gain-controlled amplifier and a limiter, which reduces the amplitude and power of the desired signal relative to the interfering signal. The combination of constant amplitude and limited signals results in significant attenuation of the interfering signal while causing minimal attenuation of the desired signal.
