Abstract
Compensation measurements can be made of the transmit and receive path circuitry of a dual FDD/TDD system which can be selectively operated in either the FDD mode or alternately in the TDD mode. BY selectively controlling the switches coupling low frequency and high frequency receivers and coupling low frequency and high frequency transmitters to a diplexer, compensation measurements can be made for both FDD and TDD modes of operation.
