Abstract: A broadband spectrum channelizer employing pulsewidth-modulated local-oscillator (PWM-LO)-based sub-band amplitude control is demonstrated. The channelizer has an analog bandwidth of 800 MHz and partitions the input spectrum into eight contiguous sub-bands. The design employs an… read more here.

Abstract: Radiofrequency (RF) channelization has potential high frequency and wideband advantages in frequency-domain channel segmentation and down-conversion reception. In this paper, we propose a compact dual-channel channelizer that can process high-frequency wideband signals. It uses double-polarization… read more here.
