Abstract :
This paper presents simulation results of the receiver section of a frequency-hopped spread-spectrum transceiver operating in the 863-870 MHz European band for wireless sensor applications. The receiver is designed for binary frequency-shift keying (BFSK) modulation, communicating a maximum data rate of 20 kb/s. The receiver combines a low-noise amplifier with down conversion mixer, a low-pass channel-select filter and a limiter. The various blocks parameters of the receiver like noise figure, gain and IIP3 are simulated and optimized to meet receiver specifications. The receiver simulations show 51.1 dB conversion gain, -7 dBm IIP3, -15 dB return loss (S11) and 10 dB NF
