Abstract :
This work presents the design and measurement of a 2 Mbps BFSK transceiver at 1.35 to 1.75 GHz for use in wireless sensor node applications. The receiver is a direct conversion architecture and has a sensitivity of -74 dBm at 2Mbps and consumes 8.0 mW. The transmitter generates orthogonal BFSK modulation through the use of digital pre-emphasis of the synthesizer frequency control word and consumes 9.7 mW including the power amplifier. The transmitter delivers >3 dBm of output power for a total transmitter power efficiency of 23% and a transmitter FOM of 4.85 nJ/bit at 2 Mbps.
