摘要： A method for calibrating a radio frequency (RF) transmitter begins by mixing a modulated RF signal with an in-phase (I) component of a local oscillation or a quadrature (Q) component of the local oscillation to produce a baseband representation of the modulated RF signal. The method continues by converting the baseband representation of the modulated RF signal into a digital baseband signal. The method continues by filtering the digital baseband signal to produce at least one frequency spectrum component. The method continues by interpreting the at least one frequency spectrum component to produce a calibration signal. The method continues by calibrating at least one of DC offset and gain offset of digital transmitter processing module based on the calibration signal.

摘要： A radio receiver includes a single analog to digital converter, a 1st digital mixing module, and a 2nd digital mixing module. The single analog to digital converter is coupled to convert the filtered IF signal into a digital IF signal, which includes information regarding an in-phase component and a quadrature component of a modulated RF signal. The 1st and 2nd mixing modules each receive the digital IF signal and mix the digital IF signal with an in-phase and quadrature digital local oscillation to produce a 1st baseband signal component and a 2nd baseband signal component.

摘要： A Radio Frequency RF transmitter includes a translational loop architecture that supports non-constant envelope modulation types and includes by adjusting the envelope of the translational loop at the translational loop output. The RF transmitter includes an Intermediate Frequency (IF) modulator, a translational loop, an envelope time delay adjust block, an envelope adjust block, and a time delay calibration block. The IF modulator receives a modulated baseband signal and produces a modulated IF signal having a non-constant envelope. The translational loop receives the modulated IF signal and produces a modulated RF signal having a constant envelope. The envelope time delay adjust block receives an envelope signal corresponding to the original modulated signal and produces a time delayed envelope signal based upon a time delay control signal. The envelope adjust block adjusts the modulated RF signal based upon the time delayed envelope signal to produce an envelope adjusted modulated RF signal. Finally, the time delay calibration block receives the envelope adjusted modulated RF signal and produces the time delay control signal.

摘要： A method of distributing an array of interconnects on an electronic device divides the array into multiple regions, each region having certain performance requirements. For each region, predefined performance curves are used to choose from a plurality of interconnect distribution pattern modules one or more interconnect distribution pattern modules that satisfy the corresponding performance requirements. The chosen interconnect distribution pattern modules are used to generate a performance indication map highlighting those vulnerable interconnect(s) that may suffer severe crosstalk interference. Each vulnerable interconnect is then relocated to a different location until the performance requirements are met.

摘要： A Radio Frequency (RF) receiver includes a low noise amplifier (LNA) and a mixer coupled to the output of the LNA. The gain of the LNA is adjusted to maximize signal-to-noise ratio of the mixer and to force the mixer to operate well within its linear region when an intermodulation interference component is present. The RF receiver includes a first received signal strength indicator (RSSI_A) coupled to the output of the mixer that measures the strength of the wideband signal at that point. A second received signal strength indicator (RSSI_B) couples after the BPF and measures the strength of the narrowband signal. The LNA gain is set based upon these signal strengths. By altering the gain of the LNA by one step and measuring the difference between a prior RSSI_B reading and a subsequent RSSI_B′ reading will indicate whether intermodulation interference is present.

LNA gain is determined during a guard period preceding an intended time slot of a current frame and during a guard period following an intended time slot of a prior frame. The lesser of these two LNA gains is used for the intended time slot of the current frame.
