The MR2001 is an expandable three package solution for automotive radar modules. The chipset consists of a VCO (voltage controlled oscillator), a two-channel Tx transmitter, and a three-channel Rx receiver. The MR2001R is a high performance, highly integrated, three-channel, receiver (RX) ideally suited for automotive radar applications. In conjunction with the MR2001V, a four-channel voltage controlled oscillator, and an MR2001T, a two-channel transmitter, it provides an expandable three package solution for automotive radar modules.

The chips are connected together via the LO signal around 38 GHz. The individual control of each chip is realized by SPI. The main controller and modulation master is a single microprocessor (MCU) with integrated high-speed analog to digital converters (ADC) and appropriate signal processing capability such as fast fourier transforms.

The front-end solution is specifically architected to be controlled by NXP's Qorivva MPC5775 MCU. Especially the baseband functionality (high-pass filters, variable gain amplifiers, anti-aliasing filters) on the receiver chips has been designed to work with the MPC5775 MCU.
