Method and arrangement for transmitting and receiving RF signals through various radio interfaces of communication systems

摘要: A method and arrangement for transmitting receiving RF signals, associated with different radio interfaces of communication systems, employ a direct conversion based transceiver which substantially comprises one receive signal branch transmit branch. Mixing frequencies the systems are generated by single common use an output frequency divider in combination synthesizer, filtering corresponding to system channel bandwidth means controllable low-pass filter operating at baseband frequency.
