    摘要: A radio receiver such as a frequency modulation (FM) receiver, for example, includes a radio frequency (RF) amplifier having an adjustable gain output. The RF amplifier may be configured to receive and amplify an incoming RF signal. The receiver also includes an intermediate frequency (IF) amplifier having an adjustable gain output. The IF amplifier may be configured to receive and amplify an IF signal that corresponds to the RF signal. The receiver also includes a gain control unit that is coupled to the RF amplifier and the IF amplifier. The gain control unit may be configured to independently adjust the gain of each of the RF amplifier and the IF amplifier, dependent upon a peak output level of both the RF amplifier and the IF amplifier.

    摘要: A transceiver includes a processor, which is adapted to in a transmit mode of the transceiver, form at least part of a transmitter and in a receive mode of the transceiver, form at least part of a receiver. The transceiver may include at least one analog-to-digital converter to provide digital signals to the processor in both the transmit and receive modes of operation; and the transceiver may include at least one digital-to-analog converter to receive digital signals from the processor in the transmit and receive modes of operation. The processor may be fabricated on an integrated circuit with at least one of the analog-to-digital converters and/or with at least one of the digital-to-analog converters.
