Kaben's unique radio architecture enables reconfigurable transceiver front ends that can support multiple standards. This innovative technology occurs in the Intermediate Frequency (IF) range between the RF and the digital. The Reconfigurable IF is built around three novel circuit cores; a Sampling IF Filter which down-converts an IF directly to digital, a Digital-to-IF up-converter which converts a digital baseband directly to IF, and an ultra-low phase noise and spur level synthesizer that is used in the receive and transmit paths. The field programmable flexibility of the Reconfigurable IF provides a multi-standard transceiver capability while relaxing the associated component specifications in the up- and down-converters, LNA, and external PA. The Reconfigurable IF also removes the need for external SAW filters in the receive path, while providing all the strengths of a classic super heterodyne architecture. When using a super heterodyne approach, the Reconfigurable IF eliminates the analog baseband normally required by converting directly between IF and digital. For the receiver, this avoids DC offset and IP2 problems, and removes the need for compensation loops in the digital back-end. The elimination of the analog baseband also removes issues associated with 1/f noise. The combination of field programmable flexibility and lower component count, results in a quick time-to-market, smaller die size and a reduced BOM.
