Dual-channel RF transceiver for TDD and HFDD applications

SMI7336 is a dual-channel RF transceiver for TDD and HFDD applications. The transceiver supports a full 2 x 2 MIMO configuration with two independent transmit and receive chains. The transceiver uses direct-conversion architecture. The received RF signal is down converted to baseband. Internal switches allow adjustment of the amplitude and phase of the baseband signal to achieve optimal channel balance. The LO is generated by an internal fractional-N synthesizer capable of <100 Hz steps. The internal registers are loaded via a standard SPI interface.
