Title: Innovator Bhupendra Sarhad: Pioneering Advances in Wireless Testing Technologies
Introduction: Bhupendra Sarhad, based in Pleasanton, CA, is a prominent inventor renowned for his innovative contributions to the field of wireless technology. With a total of four patents to his name, Sarhad has made significant strides in developing devices that enhance the testing of radio frequency integrated circuits.
Latest Patents: Among his latest inventions is a patent for waveguides designed to capture close-proximity electromagnetic radiation transmitted by wireless chips during testing on automated test equipment (ATE). This innovative test fixture incorporates a flexible plastic cable acting as a waveguide, optimized for a small transceiver and antenna that operates in the Extremely High-Frequency (EHF) band of 30-300 GHz. The compact design of the device-under-test (DUT) limits emitted electromagnetic radiation, necessitating close-proximity communication—an envelope for reception that only extends about a centimeter from the DUT transceiver. To efficiently capture this radiation, a slot is incorporated in the test socket near the antenna. This slot receives one end of the plastic waveguide, facilitating the conveyance of radiation to an external receiver.
Another significant patent of Sarhad's includes a module test socket for conducting over-the-air testing of radio frequency integrated circuits. This system features a test socket assembly that captures low-energy electromagnetic emissions from RF ICs. The strategic design of the assembly allows for optimal directionality of electromagnetic radiation from the DUT to a socket port coupled to a waveguide, enhancing the efficiency of emissions coupling. A reflective plane, adjustable in position, serves to further improve the capture of emissions from the DUT into the waveguide.
Career Highlights: Sarhad's impressive career has seen him contribute to key companies including Keyssa, Inc. and Keyssa Systems, Inc., where he has played a crucial role in advancing wireless chip technologies and testing methodologies.
Collaborations: Throughout his career, Bhupendra Sarhad has collaborated with several talented individuals in the field, including Christopher Scott Sansom and Roger Dwain Isaac. These collaborations have fostered an environment of innovation and cutting-edge development in wireless technologies.
