Abstract

This research work addresses simulation results of a 2.4GHz Radio Frequency (RF) transceiver with Alternate Quadrature Differential Phase Shift Keying (AQ-DBPSK) modulation at 1 Mbps. The RF transmitter consists of an AQ-DBPSK modulator, an up conversion mixer, a 2.4 GHz Band pass filter and a power amplifier. At the receiver RF front end, the Low Noise Amplifier (LNA), mixer with down conversion to Intermediate Frequency (IF), a Low Pass Filter (LPF) and an AQ-DBPSK demodulator is used. The block parameters of the transmitter and receiver RF front end like Noise Figure (NF) and gain are simulated and optimized to meet the transceiver specifications targeting wireless sensor networks.
