Abstract

This paper presents a 24-GHz radar system based on a low-power, low-noise, multichannel, scalable transceiver (TRX) monolithic microwave integrated circuit (MMIC). The MMIC features two homodyne quadrature downconversion receivers with a single-sideband noise figure (NFssb) of 8 dB and an adjustable conversion gain (CG) of up to 87dB using integrated programmable analog baseband (ABB) amplifiers. Integrated baseband bypass feature allows using the same MMIC for Doppler as well as Frequency-Modulated Continuous-Wave (FMCW) radar applications. The transmit section features a fundamental frequency voltage controlled oscillator (VCO) and two transmitters with bidirectional RF ports. The transmitter delivers a maximum output power of +5 dBm. The measured phase noise at 100kHz offset was -90 dBc/Hz. Designed in a production ready 0.13µm SiGe:C BiCMOS technology, the chip consumes 165 mA from a 1.5V power supply with all blocks turned ON and consumes less than 100µA in the standby mode.

适用于工业和消费类应用的可扩展多模24ghz雷达收发器，采用0.13 μ m SiGe BiCMOS技术

提出了一种基于低功耗、低噪声、多通道、可扩展收发器(TRX)单片微波集成电路(MMIC)的24ghz雷达系统。MMIC具有两个同差正交下变频接收器，其单边带噪声系数(NFssb)为8 dB，可调转换增益(CG)高达87dB，采用集成可编程模拟基带(ABB)放大器。集成基带旁路功能允许在多普勒和调频连续波(FMCW)雷达应用中使用相同的MMIC。发射部分具有一个基频压控振荡器(VCO)和两个具有双向射频端口的发射器。发射机的最大输出功率为+5 dBm。在100kHz偏移处测量的相位噪声为-90 dBc/Hz。该芯片采用生产就绪的0.13 μ m SiGe:C BiCMOS技术设计，在所有模块都打开的情况下，从1.5V电源消耗165 mA，待机模式消耗低于100 μ a。
