The MT3812 from Metanoia is a Tri-Band 5G Sub-6 GHz 5G-NR Transceiver with support for 2x2 MIMO. It has a scalable architecture which can help in building higher density applications by using multiple instances of the chip. The transceiver supports 50 to 200 MHz channel bandwidth (BW) in the TX mode and 20 to 200 MHz channel BW in the RX mode. It also supports 400 MHz BW in loopback mode for Digital Pre-Distortion (DPD) in the TX chain. The transceiver uses a direct conversion architecture for both Receive (RX) and Transmit (TX) modes with an integrated programmable digital core for transceiver control and calibration, auxiliary ADC support for calibration, and external functions, and a flexible analog baseband filter.
The transceiver also has a 122.88 MHz external oscillator for frequency reference, a 400 MHz PA output observation RX path, and a second independent Local Oscillator (LO) for use in I/Q calibration. It supports a Low Voltage Differential Signaling (LVDS) bus for bi-directional data exchanges with the baseband and can be controlled via a traditional low-speed SPI bus interface.
The MT3812 is available in a 68-pin DR-QFN package and is ideal for Open Radio Access Network (O-RAN) Radio Units (RU), local area/medium range base station, small cell systems, and customer-premises equipment (CPE) applications.
