Title: Raju Kharataram Chaudhari: Innovator in RF Technology

Introduction

Raju Kharataram Chaudhari is a prominent inventor based in Pune, India. He has made significant contributions to the field of radio frequency (RF) technology, holding a total of 4 patents. His innovative work focuses on enhancing communication systems and improving signal processing techniques.

Latest Patents

One of his latest patents is titled "Enhancing TX-TX isolation through digital pre-compensation." This invention involves a TX-TX pre-compensation system that estimates unwanted coupling in a victim transmit chain caused by an aggressor transmit chain. It injects a pre-compensation signal to cancel out the estimated coupling. The system includes a signal measurement module that estimates the amplitude, phase, and envelope delay of the coupling. Additionally, an isolation pre-compensation module generates the pre-compensation signal based on these estimates and the difference between the carrier frequencies of the transmit chains. The phase and amplitude of the pre-compensation signal can be adjusted in response to changes in carrier frequency and attenuator gain settings.

Another notable patent is "Dual-band AGC for RF sampling receivers." This integrated circuit comprises various components, including a digital step attenuator and an analog-to-digital converter. It is designed to output a digital signal that includes two frequency ranges. The system utilizes bandwidth filters and band attack and decay detectors to manage the automatic gain control based on detected band peaks or decays.
