Transmitter and receiver modules for 60-GHz multi-gigabit per second (multi-Gbps) communications are presented. The On-Off-Keying (OOK) modulation scheme is utilized to minimize the system complexity and thus the power consumption. The transmitter module consists of voltage-controlled oscillator (VCO), OOK modulator and medium-power power amplifier (PA), while the receiver requires only low-noise...
This paper describes a novel method for compensating ramp leakage in frequency modulated continuous wave (FMCW) radar applications that is not canceled by deramping. With a closed loop compensation algorithm it is possible to increase the signal to leakage ratio of common single chip FMCW radars by orders of magnitude in ideal situations. The loop consists of a DC-coupled FMCW radar frontend including...
