Abstract

A multistandard RF transceiver is disclosed that may optionally include selectable mixers; selectable amplifiers; a configurable analog filter; and a configurable analog to digital converter. The multistandard RF transceiver may also include a data interface for sending data to a host controller and a control interface for receiving configuration commands from the host controller. The configuration commands identify a wireless standard that is to be implemented by the RF receiver. An RF processor processes an RF signal wherein the processed RF signal is output to the host controller on the data interface.

Claims

1. A multistandard RF receiver comprising:

a data interface for sending data to a host controller;

a control interface for receiving configuration commands from the host controller wherein the configuration commands identify a wireless standard that is to be implemented by the RF receiver; and

an RF processor for processing an RF signal wherein the processed RF signal is output to the host controller on the data interface.

2. A multistandard RF transmitter comprising:

a data interface for receiving data from a host controller;

a control interface for receiving configuration commands from the host controller wherein the configuration commands identify a wireless standard that is to be implemented by the RF transmitter; and

an RF processor for processing an RF signal wherein the processed RF signal is transmitted in accordance with the wireless standard.

3. A multistandard RF transceiver comprising:

a plurality of selectable mixers;

a plurality of selectable amplifiers; and

a configurable digital signal processor that is configured to process a received signal or a signal that is being transmitted.
