摘要： A translation loop signal upconverter is disclosed. Embodiments of the invention minimize n th order harmonics and spurious tones in the radiofrequency output spectrum of a portable transceiver. In one embodiment, the invention is a signal upconverter, comprising a modulator configured to develop a modulated intermediate frequency (IF) signal at a fundamental frequency, the modulated IF signal also including a plurality of n th order components, a synchronous oscillator configured to receive the modulated IF signal, the synchronous oscillator also configured to operate at the fundamental frequency of the modulated IF signal, thereby providing an IF signal substantially free of the n th order components, and a translation loop having a phase locked loop, the translation loop configured to receive the IF signal output of the synchronous oscillator, and supply a radio frequency (RF) output signal to a power amplifier.

摘要： A software defined transmit architecture includes a plurality of individually selectable components that can be selectively enabled to transmit a data signal that complies with any of a plurality of transmission standards. The software defined transmit architecture comprises components that can be enabled by associated logic to transmit, for example, communications signals that comply with the global system for mobile communications (GSM), enhanced data rates for GSM evolution (EDGE), which employs TDMA, and wide band code division multiple access (WCDMA) transmission standards. A single transmit architecture supports multiple transmission standards, thus minimizing the number of components in a multi-band, multi-mode portable transceiver, while reducing the number of active components.

摘要： An amplifier chain with sequential DC offset correction for use in a radio receiver is provided. The amplifier chain has at least first and second amplifier stages connected in series. The first and second stages include an amplifier and a track and hold circuit connected in parallel across the amplifier. The track and hold circuit has a tracking state and a holding state. A control signal is coupled to the track and hold circuits of the first and second stages. The control signal is configured to set the track and hold circuits to the tracking state, which may be done simultaneously, and to sequentially set the track and hold circuit of the first stage to the holding state and then set the track and hold circuit of the second stage to the holding state.

摘要： A subharmonic mixer (106) and a method of downconverting a received radio frequency signal is described. The subharmonic mixer (106) of the present invention uses two stacks of switching cores (184, 186) with high order symmetry to reduce unwanted harmonic generation and uses transistors (Q1-Q24) to improve headroom.
