Title: The Innovations of Daniel E. Fague
Introduction
Daniel E. Fague is a notable inventor based in Sunnyvale, CA. He has made significant contributions to the field of telecommunications, holding a total of 4 patents. His work primarily focuses on improving communication systems through innovative filtering techniques and transceiver designs.
Latest Patents
One of Fague's latest patents is an equalization filter compensating for distortion in a surface acoustic wave (SAW) device. This invention enhances the modulation accuracy of communication systems by utilizing an equalizer filter to predistort signals, thereby equalizing the SAW filter response. The approach involves convolving the original baseband filter impulse response with the inverse of the actual SAW filter impulse response, resulting in coefficients for a digital filter that forms part of a DQPSK modem. This method effectively mitigates modulation errors caused by the original baseband filter.
Another significant patent is for a radio frequency (RF) telecommunications transceiver. This device features a direct modulation transmitter and a single down-conversion receiver, designed for operation in a time-division-duplex (TDD) environment. The transceiver employs a phase-lock-loop (PLL) as a single RF signal source, which is time-shared between the transmitter and receiver. The design includes a self-adjusting comparator threshold for optimizing data retrieval from the demodulated receive signal, ensuring efficient power consumption.
