摘要： A front end circuit for coupling an antenna to a radio frequency (RF) transceiver is disclosed. An antenna port connectible to the antenna is provided, as well as a power amplifier coupled to a signal output of the RF transceiver and a low noise amplifier coupled to the signal input of the RF transceiver. The front end circuit includes a switching network that is connected to the antenna port, the power amplifier, and the low noise amplifier. Additionally, there is at least one resonant circuit and a control circuit coupled to a receive enable line of the transceiver. This resonant circuit defines a parallel resonance with a first resonant resistance in the operating frequency band upon activation in the receive mode. The resonant circuit also defines a substantially high transistor impedance upon deactivation in the transmit mode.

摘要： A printed circuit board (PCB)-printed antenna for a radio frequency (RF) front end with an antenna port for a predefined operating frequency band. A radiating element with a first branch defined by a first set of dimensions corresponding to a minimum frequency and a second branch defined by a second set of dimensions corresponding to a maximum frequency is fixed to a PCB substrate. A third branch is defined by a third set of dimensions corresponding to a middle frequency in various embodiments. A feed line is electrically connected to the radiating element and defines a feed port that is connectable to the antenna port. A ground line is electrically connected to the radiating element and defines a ground port. The first branch defines a first resonance, the second branch defines a second resonance, and the third branch defines a third resonance, all of which are superposed to define a bandwidth of the radiating element that is substantially equivalent to the predefined operating frequency band of the RF front end.
