“…This technique enables the manufacturing of identical chips of smaller size and hence higher yield at lower cost but puts additional emphasis on the assembly process. Using this principle, a scalable radar platform based on single-channel transceiver circuits has been presented in [37] and is shown in Fig. 4.…”

This invited paper reviews the progress of silicon-germanium (SiGe) bipolar-complementary metal-oxidesemiconductor (BiCMOS) technology-based integrated circuits (ICs) during the last two decades. Focus is set on various transceiver (TRX) realizations in the millimeter-wave range from 60 GHz and at terahertz (THz) frequencies above 300 GHz. This article discusses the development of SiGe technologies and ICs with the latter focusing on the commercially most important applications of radar and beyond 5G wireless communications. A variety of examples ranging from 77-GHz automotive radar to THz sensing as well as the beginnings of 60-GHz wireless communication up to THz chipsets for 100-Gb/s data transmission are recapitulated. This article closes with an outlook on emerging fields of research for future advancement of SiGe TRX performance.

“…In this work, we chose to use the 79 GHz radar developed by IHP using 130 nm SiGe BiCMOS technology [21], due to the optimised power amplifier (PA) that can output 19.2 dBm maximum output power and the high antenna gain of 14.4 dBi. In addition, the 79 GHz carrier frequency provides high detection sensitivity of the very small vibration of body and large dynamic range.…”

“…This results in a large space requirement on the PCB and additionally needed amplifiers (integrated or assembled on the PCB) and therefore increased costs. By feeding the FMCW signal through all MMICs in a daisychained manner [13], [14], these drawbacks can be overcome. Since the FMCW signal is generated by a single local oscillator (LO), such systems are denoted as LO feedthrough [15].…”

The estimation of the direction-of-arrival in a coherent multi-channel radar system requires the distribution of the high-frequency local oscillator signal to all hardware channels. Various system concepts with distribution network or feedthrough topologies are established. While distribution networks are bulky and costly, the time delays in systems with a feedthrough topology cause systematic errors in the range evaluation. In this work, a system concept based on an injection-locked feedthrough and the related radar system analysis is presented. The disadvantage of time delays in common feedthrough architectures can be eliminated by a hardware correction using the phase shifting capabilities of the injection-locked oscillator. In addition, two software correction algorithms are presented and analyzed. The performance of the realized system is shown by radar measurements and direction-of-arrival estimations. It is proven that the phase noise of different injection-locked oscillators is fully correlated within the radar system which results in the same detection performance as in state-of-the-art radar systems using a signal distribution network. Thus, the injection-locked feedthrough imaging radar topology is a suitable concept of realizing flexible radar frontends without bulky distribution networks.INDEX TERMS Automotive radar, chirp sequence modulation, coherency, direction-of-arrival (DoA) estimation, frequency modulated continuous wave (FMCW), injection-locking, imaging radar, local oscillator (LO) feedthrough, mm-wave, monolithic microwave integrated circuit (MMIC), multiple-input multipleoutput (MIMO), phase noise correlation, time delay correction.This article has been accepted for inclusion in a future issue of this journal.
