Benefits of technology

The patent text describes a wireless communication device that includes a built-in radio transceiver for wireless communication. The device includes a plurality of integrated circuits and discrete components that are necessary to achieve the strict performance requirements of specific wireless communication standards. The technical effect of this invention is to provide a more efficient and cost-effective way to implement wireless communication devices that support multiple wireless communication standards.

Problems solved by technology

Redesigning the analog portions, however, is not a straightforward task since most analog circuitry (e.g., inductors, capacitors, etc.) does not “shrink” with the IC process.

Abstract

A receiver includes a sample and hold module, a discrete time filter module, and a wireless frequency to baseband conversion module. The sample and hold module is operable to sample and hold an inbound wireless signal at a rate corresponding to a multiple of a carrier frequency of the inbound wireless signal to produce a frequency domain sample pulse train. The discrete time filter module is operable to filter the frequency domain sample pulse train to produce a wireless frequency pulse. The wireless frequency to baseband conversion module is operable to convert the wireless frequency pulse to a baseband digital signal.
