摘要： An RF or other high frequency transceiver including a loopback reference channel for measurement of an absolute power level. A transmit channel in the transceiver includes a programmable power amplifier that can be controlled to operate at a selected power level, and a receive channel including a receive amplifier, mixers, filters, and analog-to-digital converters. The loopback reference channel includes a self-biased amplifier, followed by a series of buffers that generate a square wave from the received signal, and an attenuator applying an attenuation gain to the square wave. The transmit power at a programmed power level can be calculated from ratios of a measured power level of a transmitted signal as received by the receive channel to the measured power level of the transmitted signal using the loopback reference channel.

摘要： A system on a chip (SoC) includes a transceiver comprising a transmitter and a receiver, wherein at least one of the transmitter and receiver has a configurable portion that can be configured to operate in a single ended mode and in a differential mode. Two interface pins are provided for coupling the transceiver to an antenna via a matching network, wherein the two interface pins are shareably coupled to the transmitter and to the receiver. A tunable capacitor is coupled to differential signal lines of the configurable portion, wherein the tunable capacitor is configured to be tuned to optimize impedance matching of the configurable portion for each mode of operation.
