SMI7335 2x2 Multi-band MIMO

Dual-channel RF transceiver for TDD and HFDD applications

Product Description

SMI7335 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 downconverted 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. 4 Supports BW's of 3.5, 5, 7, 8.75, 10, 14 and 20 MHz 4On-chip peak and log detectors
