Patent ID: 8428650

Claim:
A reconfigurable radio frequency (RF) transceiver, for use in a micro-base station and configured for low cost and low power consumption, the reconfigurable RF transceiver comprising: a duplexer configured to receive an incoming RF signal in a selectable receive frequency band and to transmit an outgoing RF signal in a selectable transmit frequency band; a first receive path in an application-specific integrated circuit (ASIC) coupled to the duplexer, the first receive path configured to receive the incoming RF signal in a selectable receive frequency band and to down-convert the incoming RF signal to at least one of an analog baseband signal and a digital baseband signal; a transmit path in the ASIC, the transmit path configured to receive the outgoing baseband signal and to up-convert the outgoing baseband signal to an outgoing RF signal in a selectable transmit frequency band, wherein the transmit path is also configured to receive a signal from a digital RF interface block that comprises at least one serial digital function and at least one Gaussian Minimum Shift Key (GMSK) modulator; a plurality of configuration registers in the ASIC, each configuration register configured to store at least one modifiable configuration parameter, wherein the modifiable configuration parameters configure at least one multiplexer receiver and one intermediate frequency processor, wherein the modifiable configuration parameters are used to promote communication with a plurality of frequency bands and communication standards; a plurality of low-noise amplifiers (LNAs) in the ASIC and coupled to the duplexer, at least some of the LNAs designed for different frequency bands and communication standards, wherein unused LNAs are configured to be powered down to minimize power consumption; and an integrated central processing unit/network processing unit (CPU/NPU) configured to use the modifiable configuration parameters to handle data plane processing, management plane processing, to control panel plane processing, and to allow the RF transceiver to be fully reconfigured at a time of use.
