Wide frequency range (30 M-1 GHz) low noise figure, low power, active CMOS mixer

摘要

In this paper we present the design methodology and implementation of a wide frequency range (30 MHz-1 GHz) low-power, Integrated CMOS mixer. The mixer has a high conversion gain (12 dB), and a low noise figure (9.2 dB) and operates at 3.3 V. The mixer is designed for low power mobile transceiver (user sets), where power consumption is a key issue. The wide frequency band and dynamic range of the mixer makes it suitable for both homodyne (zero-IF) and heterodyne mobile transceivers.
