Abstract: A method and apparatus is provided that amplitude modulates a modulated radi o frequency (RF) signal (411) by modulating the supply voltage of a power amplifier (410). The method and apparatus further provide an impedance modulator (412) that reduces output signal (415) errors in response to an error signal generated by a feedback circuit (416) that includes a quadratur e modulator (506), a limiter (520), a comparator (502), and a quadrature downconverter (510). Intermodulation distortion generated in the feedback circuit (416) by delay mismatches between amplitude and phase feedback paths , and non-linear effects of AM/PM conversion in a limiter (520), are suppresse d by placing limiter (520) and quadrature downconverter (510) in a forward pat h of the overall amplifier loop.

Abstract: CM-00401G LOW POWER DIGITAL RECEIVER A low power digital receiver (10) is provided that contemporaneously selects the lowest possible sampling signal frequency (34) (from a plurality of available sampling signals), and received signal level (28) to properly digitize (32) and recover a desired signal. Digitization is performed after the first IF using broadband stages (28, 30, and 32) that are temporarily enabled (44) to rapidly digitize the first IF signal. This, together with the low sampling rate, minimizes the power consumption of the receiver (10) thereby permitting portable and mobile digital receiver embodiments.

Abstract: A wireless communication unit provides (10) a first signal as received from a first portion (11) of a single antenna and provides (13) a second signal as received from a second portion of the antenna, which in a preferred embodiment can comprise a feedline (12). The two signals contain information that is cross-coupled with respect to one another as a function, at least in part, of the structure of the antenna. A digital processing platform (34) de-couples (17) these signals to permit recovery of the original payloads. In one embodiment similar approaches are used to facilitate cross-coupling of signals and transmission of such cross-coupled signals from different portions of a single antenna structure. In another embodiment, both transmission and reception are facilitated by a common platform.

Abstract: The present invention addresses the need for an apparatus and method for controlling the load of a PA, to improve PA efficiency in linear transmitters with isolator elimination (IE) circuitry, that does not require the use of high frequency RF circuitry. The present invention provides a PA load controller (130, 131) that improves the efficiency of a PA (116) by adjusting the PA load using an AGC signal (134), a level set adjustment signal (132), and a signal strength indicator (135), these three signals are readily obtained from continuous gain and phase adjustment circuitry (e.g., 102). The load controller determines a phase of the PA load that minimizes the AGC signal and a phase of the PA load that maximizes the level set adjustment signal. From these determinations, the PA load controller determines a phase of the PA load that improves the efficiency of the PA and adjusts the PA load phase accordingly.

Abstract: An integrated sigma-delta radio frequency (RF) receiver subsystem (200) and method utilizes a multi-mode sigma-delta analog-to-digital converter (215) for providing a single and multi-bit output. A programmable decimation network (221) for reducing the frequency of the in-phase and quadrature bit stream and a programmable formatting network (223) are also used for organizing the in-phase and quadrature components from the decimation network (221) for subsequent signal processing. The invention offers a highly integrated digital/analog RF receiver back-end which incorporates integrated filtering and a smart gain control that is compatible for use with other receiver systems and offering superior performance characteristics.
