Japan, March 5 -- ANALOG DEVICES INT UNLIMITED COMPANY has got intellectual property rights for 'APPARATUS AND METHOD FOR RADIO TRANSCEIVER.' Other related details are as follows:
Application Number: JP,2024-181948
Category (FI): H04B1/04@Z,H04B17/10
Stage: PROBLEM TO BE SOLVED: To provide an apparatus and a method for transceivers.SOLUTION: In a first aspect, an observation receiver is implemented to detect common-mode local oscillator (LO) leakage while the observation receiver performs other functions. In a second aspect, a transceiver is implemented with an LO leakage compensation circuit that compensates a transmitter for LO leakage using a digital filter, such as a Kalman filter, that combines differential LO leakage observations with common-mode LO leakage observations. In a third aspect, a transmitter includes multiple local loopback paths including a first loopback path after a variable gain amplifier (VGA) and a second loopback path before the VGA.SELECTED DRAWING: Figure 1 (Grant)
