Abstract :
Transmitter Leakage has a significant impact on zero-IF transceivers for mobile FDD terminals and therefore must be compensated. When Tx Leakage compensation approaches are designed, their capability to adapt to changing leakage conditions must be specified. Therefore, in this contribution we analyse the time variance of Tx Leakage considering the UMTS SAW duplexer B7632 of EPCOS as an example and derive a worst case estimate of Tx Leakage coherence time.
