A radio frequency (RF) transceiver Integrated Circuit (IC) comprising:

• a plurality of baseband Rx sections operable to receive, filter, and gain adjust respective Rx baseband signals;
• a plurality of baseband Tx sections operable to receive, filter, and gain adjust respective Tx baseband signals;
• a first RF transceiver section and a second RF transceiver section, each of the first RF transceiver section and the second RF transceiver section comprising:
• a plurality of RF Tx sections, each operable to receive, filter, gain adjust, and up convert a respective Tx baseband signal to produce a respective Tx RF signal;
• a plurality of RF Rx sections, each operable to receive, filter, gain adjust, and down convert a respective Rx RF signal to produce a respective Rx baseband signal;
• a static digital interface operable to receive static gain control commands from a coupled baseband processor;
• a first dynamic digital interface operable to receive dynamic gain control commands from a coupled baseband processor for application to the first RF transceiver section;
• a second dynamic digital interface operable to receive dynamic gain control commands from the coupled baseband processor for application to the second RF transceiver section;
