A Low-Power WCDMA Transmitter with an Integrated Notch Filter
Ahmad Mirzaei, Hooman Darabi
In a WCDMA FDD system, since the transmitter and receiver operate concurrently, the receiver is plagued by the transmitter leakage due to finite isolation of antenna duplexer. As a consequence, the transmitter noise at t
