摘要： An integrated circuit includes a linearizer circuit in which excessive delay is compensated. The linearizer circuit includes a power amplifier, forward and feedback paths, and a microprocessor. A signal from the power amplifier is routed by the forward path to be transmitted while a portion of the signal to be transmitted is routed back to the power amplifier via the feedback path. The microprocessor applies phase training signals to the forward path. The microprocessor uses the phase training signals to determine the amount of delay in the linearizer circuit and alters the frequency position of poles and zeros in the linearizer circuit to compensate for the delay. The gain of the linearizer circuit is also altered by the microprocessor depending on the measured delay.

摘要： A wireless subscriber communication unit (200) comprises an antenna arrangement (202, 330, 430) for radiating and/or receiving electromagnetic signals. A transmitter (220) and/or a receiver (210) is/are operably coupled to the antenna arrangement (202, 330,430), for transmitting/receiving a radio signal. An antenna arrangement comprises a first antenna located within the wireless communication unit (200) and an external antenna located substantially outside of the wireless communication unit, such that both the internal antenna (330, 430) and the external antenna (202) co-operate on substantially the same electromagnetic signal, e.g. to produce a desired combination of phases. In this manner, by provision of both an internal and an external antenna the wireless subscriber communication unit is able to function adequately should an antenna become disconnected, malfunction, or its performance suffer from impedance mismatching. The internal and external antennas can be configured to have the same signal phases, e.g. to process a linearly polarised signal, or orthogonal to one another, thereby providing the wireless subscriber unit with the ability to operate with a substantially circular or elliptical signal polarisation.
