摘要： In a radio comprising a transmitter and a receiver, transmission and reception of signals may be controlled based on received signal strength measurements from a signal strength indicator module and transmitted signal strength measurements from the signal strength indicator module. For the transmitted signal strength measurements, the shared signal strength indicator module may measure signal strength of a signal output by a power amplifier. For the received signal strength measurements, the shared signal strength indicator module may measure signal strength of a received signal. A capacitance coupled to an output of the power amplifier may be configured based on a frequency of the signal output by the power amplifier. A gain of the power amplifier may be controlled based on the transmitted signal strength measurements. For the transmitted signal strength measurements, an analog-to-digital converter may process the signal output by the power amplifier.

摘要： Methods and systems for optimal frequency planning for an integrated communication system with multiple receivers may include adjusting a center frequency of a low IF signal to reduce interference by a second order interference signal. The center frequency may be adjusted to avoid high power portions of the second order interference signal. The interference level corresponding to a center frequency may be determined by, for example, a SNR of the low IF signal, or by determining a BER for the low IF signal. The center frequency of the low IF signal may be dynamically adjusted to keep second order interference level at an acceptable level. Adjusting the center frequency of the low IF signal may also comprise keeping the low IF signal from being blocked by a DC component of the second order interference signal.

摘要： In RF transceivers, a method and a system for a frequency feedback adjustment in digital receivers are provided. A DC offset may result from the difference in frequencies between an RF transmitter and an RF receiver. An adjustment of the receiver's frequency may be implemented after synchronization occurs and may be performed by, for example, utilizing a header portion of a packet communicated via a wireless interface. The adjustment may be performed when the frequency difference exceeds a threshold value. In another aspect, adjusting the frequency of the RF receiver may be performed by modifying and/or changing a phase locked loop (PLL) trimmer register. This approach may allow an RF receiver to operate, in some instances, without the need for an equalizer. In this regard, the power consumed by the RF receiver may be minimized and/or the overall cost of the RF receiver may be reduced.

摘要： Methods for removing complexity from a Bluetooth processor's firmware and placing them in hardware in order to use a simplier processor or to do other tasks in the Bluetooth processor. Assembling and managing communication packets and transmission, providing modulo divides, and allocating memory are typical firmware tasks for a Bluetooth device. By creating circuits that assemble and manage communications packets and transmits, provide modulo divides, and manage Bluetooth device memory a processing burden can be removed from the Bluetooth processor. This lessened processing requirement allows less expensive, e.g. slower, processors to be used, or other functions to be incorporated into the processor's firmware.
