Abstract
This article presents the design and experimental results of a low‐power dual‐band RF receiver front‐end including a dual‐band low‐noise amplifier (LNA) and a downconversion mixer based on the IEEE 802.15.4 standard for sensor node applications. A dual‐band LNA with two inputs is tuned to two resonant frequencies by controlling the voltage on a switched MOS. The implemented RF receiver front‐end achieves a maximum voltage conversion gain of 31 and 21 dB, a noise figure of 6 and 9 dB at the 868/915 MHz and 2.45 GHz bands, respectively. The RF receiver front‐end dissipates a total of 3 mA (including I/Q mixers) under a supply voltage of 1.8 V at both operation bands. © 2009 Wiley Periodicals, Inc.
