[原创] ADI ADF5902 24GHz汽车雷达(MMIC)解决方案

ADI公司的ADF5902是24GHz微波集成电路(MMIC)发送器(TX),集成了24GHz压控振荡器(VCO),具有分数N频率合成器和可编栅阵列(PGA)和用在雷达系统的两路发送器.每个发送器包括功率控制电路和片上温度传感器.控制通过4线串行外设接口(SPI)进行,主要用在汽车雷达,工业雷达和微波雷达传感器.本文介绍了ADF5902主要特性,功能框图,FMCW雷达框图以及评估板EV-ADF5902SD1Z主要特性,电路图,材料清单和PCB设计图.

The ADF5902 is a 24 GHz transmitter (Tx) monolithic microwave integrated circuit (MMIC) with an on-chip, 24 GHz voltage controlled oscillator (VCO). The VCO features a fractional-N frequency synthesizer with waveform generation capability with programmable grid array (PGA) and dual transmitter channels for radar systems. The on-chip, 24 GHz VCO generates the 24 GHz signal for the two transmitter channels and the local oscillator (LO) output. Each transmitter channel contains a power control circuit. There is also an on-chip temperature sensor. Control of all the on-chip registers is through a simple, 4-wire serial peripheral interface (SPI). The ADF5902 comes in a compact, 32-lead, 5 mm×5 mm LFCSP package.

ADF5902主要特性:

24 GHz to 24.25 GHz VCO (industrial, scientific, and medical(ISM)radio band)
2-channel 24 GHz power amplifier with 8 dBm output
Single-ended outputs ..
