Abstract: A method and apparatus is provided for partitioning a radio using a multi-chip module to group some or all of the components of the radio in a single package. In one example, a radio uses a multi-chip module, including a chip carrier. Various components of the radio reside in integrated circuits that are mounted to the chip carrier. If desired, one or more antennas can be integrated into the chip carrier.

Abstract: Radio frequency identification (RFID) reader devices are disclosed. An RFID reader device of one aspect may include a radio frequency (RF) output port operable to allow a plurality of RFID antenna modules to be coupled with the RFID reader device. An RF signal generator of the device may be coupled with the RF output port. The RF signal generator may be operable to generate an RF signal and provide the RF signal to the RF output port. A select signal generator of the device may be operable to generate a select signal. The select signal may be operable to be output to select one or more of the plurality of RFID antenna modules.

Abstract: In a power amplifier, techniques are provided for protecting the power amplifier from temperature extremes resulting from conditions such as load mismatches. After sensing the temperature of the power amplifier, the operation of the RF power amplifier is controlled accordingly. In one example, the power amplifier is shut down when the sensed temperature reaches a threshold value, which can be set to a value just below the point where permanent damage would occur. In another example, when a threshold temperature is reached, the operation of the power amplifier is changed, to prevent the temperature of the power amplifier from rising to a level that would damage the power amplifier.
