摘要： A multiple-input multiple-output (MIMO) antenna system for a mobile cellular network and method is described. The MIMO antenna system includes an array of dual-polarization patch antennas each having first and second polarization feed-points, a first polarization radio chain and a second polarization radio chain. The MIMO antenna system includes a beamformer coupled to the first and second polarization radio chains. The beamformer includes a beamformer channel for a respective feedpoint and further includes a transmit amplifier and a detector (coupler) coupled to a transmit amplifier output. In one mode of operation, a signal is transmitted via the first polarization feed-point of a dual-polarisation patch antennas and a replica of the transmitted signal may be sensed using the coupler at the output of the transmit amplifier and routed via the second polarization radio chain to a digital predistortion module. The digital pre-distortion module is configured to digitally pre-distort a signal for transmission dependent on the replica of the RF signal.

摘要： A quad LINC transmitter (200) comprises an in-phase branch (202) and a quadrature phase branch (204) which are interconnected by a separator unit (210), a complex mixer unit (218) and an output signal combining network. The in-phase branch comprises a first Chireix compensation circuit (A1,A2), a second Chireix compensation circuit (A3,A4) and switches (226). The quadrature phase branch comprises a third Chireix compensation circuit (B1,B2), a fourth Chireix compensation circuit (B3,B4) and switches (226). A quadrature input signal (206,208) is converted by the separator unit (210) and the complex mixer unit (218) into two constant envelope in-phase signals (I 1 ,I 2 ) and two constant envelope quadrature phase signals (Q 1 ,Q 2 ). The separator unit (210) outputs furthermore first and second phase signals (sign(I), sign(Q)) controlling the respective switches (226). Depending on the first phase signal (sign(I)), the two constant envelope in-phase signals (I 1 ,I 2 ) are steered through the switches (226) to either the first Chireix compensation circuit (A1,A2) or the second Chireix compensation circuit (A3,A4). Also in the quadrature branch, depending on the second phase signal (sign(Q)), the two constant envelope quadrature phase signals (Q 1 ,Q 2 ) are steered through the switches (226) to either the third Chireix compensation circuit (B1,B2) or the fourth Chireix compensation circuit (B3,B4).

The interface region includes galvanic connection regions providing a galvanic connection between the each of the first substrate ground pads and each of the corresponding second substrate ground pads. The interface region includes dielectric regions between each of the first substrate RF signal pads and the corresponding second substrate RF signal pads so that RF signals transmitted between the two substrates are capacitively coupled.
