TRANSMITTER AND/OR RECEIVER MODULE

摘要

The transmitter and/or receiver module comprises a dipole antenna (28) and a matching circuit (26) matching the output impedance of the module to the antenna impedance, a switch circuit (24) for switching between received and transmitted signals, a power amplifier (30) for amplifying the transmitted signal, and a low-noise receiver amplifier (32) for amplifying the received signal, wherein the matching circuit (26) and the antenna (28) are designed to provide a bandpass filter function for the module. Differential signals are provided from the transmitter power amplifier (30) to the antenna (28) and/or from the antenna (28) to the receiver amplifier (32) without conversion of the differential signals to single-ended signals.
