CBMRF001-Corebai Microelectronics (Beijing) Co., Ltd

CBMRF001 is a high-performance, highly integrated radio frequency (RF) agile transceiver for 3G and 4G base station applications. The programmability and wideband capability of this device make it an ideal choice for a variety of transceiver applications. The device integrates the RF front-end with a flexible mixed-signal baseband section, incorporates a frequency synthesizer, and provides a configurable digital interface for the processor, thereby simplifying design implementation. The CBMRF001 operates in the frequency range from 70 MHz to 6.0 GHz, covering most licensed and unlicensed frequency bands, and supports a channel bandwidth range from less than 200 kHz to 56 MHz. The two independent direct-conversion receivers feature leading noise figure and linearity. Each receive (RX) subsystem has independent automatic gain control (AGC), DC offset correction, quadrature correction, and digital filtering functions, eliminating the need to provide these functions in the digital baseband. The CBMRF001 also has a flexible manual gain mode that supports external control. Each channel is equipped with two high dynamic range ADCs, which first digitize the received I and Q signals, then pass them through a configurable decimation filter and a 128-tap finite impulse response (FIR) filter, and generate 12-bit output signals at the corresponding sampling rate.
The transmitter adopts a direct-conversion architecture, which can achieve high modulation accuracy and ultra-low noise. This transmitter design results in a TX EVM of less than <−40 dB,leaving considerable system margin for the selection of external power amplifiers. The on-board transmit (TX) power monitor can be used as a power detector to achieve highly accurate TX power measurement. A fully integrated phase-locked loop (PLL) provides low-power fractional-N frequency synthesis for all receive and transmit channels. The design integrates the channel isolation required by frequency division duplex (FDD) systems. All VCO and loop filter devices are also integrated. The circuit uses a 10mm×10mm, 144-pin chip-scale ball grid array package (CSP_BGA). This product can effectively replace AD9361 from ADI.
