Abstract

The invention provides a wideband RF front-end. One embodiment of the present invention includes a transceiver for wireless communication. The transceiver includes an antenna, a transmitter, which comprises a tunable matching network and a modulator, and a receiver, which comprises a programmable band-pass filter (BPF) and a demodulator.

Description

technical field [0001] The present disclosure generally relates to RF front ends of wireless communication systems. More specifically, the present disclosure relates to a wideband RF front end. Background technique [0002] Conventional wireless communication systems are usually designed for specific standards, such as GSM (Global System for Mobile Communications) or Wideband Code Division Multiple Access (W-CDMA), each of which requires a different carrier frequency. For example, the carrier frequency of a GSM signal varies from 800MHz to 1GHz, while that of a W-CDMA signal varies between 2-3GHz. The current need for wireless service convergence where users can access different standards from the same wireless device is driving the development of multi-standard and multi-band transceivers capable of operating across the entire wireless communication spectrum (from 300 MHz to 3 GHz) ) to send / receive wireless signals. [0003] To meet multi-standard and multi-band require...
