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.
