Latest Patents

One of Grubman's latest patents is titled "Phase Shifter Self-Test." This invention outlines methods and circuits designed to verify the operation of phase shifters. The method involves obtaining a first set of in-phase and quadrature components (I,Q) of a phase shifter output signal with a first setting. It also includes measuring a second set of components (I,Q) with a second setting, which is offset from the first by a predetermined phase difference. By combining these sets, the relationship can be determined to correspond to the predetermined phase difference. The illustrative transmitter described in this patent includes a phase shifter, an I/Q mixer, and a processing circuit. The phase shifter converts a transmit signal into an output signal with a programmable phase shift, while the I/Q mixer mixes this output signal with a reference signal to obtain the necessary components.

Another significant patent is "Chirp Sequence Synthesis in a Dynamic Distribution Network." This invention features an array of integrated circuits that includes at least one local input port for receiving a chirp signal from a local generator. It also has primary input ports for receiving chirp signals from remote sources. The primary switch arrangement allows for switching between these signals to produce a composite signal with a chirp sequence. This sequence includes at least one chirp that begins during the settling period of a previous chirp. The design allows for flexibility in the roles of master and follower circuits during operation.
