Intended for ISM band applications, the MICRF500 operates from 700 MHz to 1 GHz, and the MICRF501 ranges from 300 MHz to 600 MHz. The MICRF 500 covers the European 868 MHz ISM frequency and the US 902 MHz to 928 MHz band. The MICRF501 is ideally suited for the 433 MHz European ISM band and the 300 MHz ISM band in the US. Ideal for battery-powered systems, these transceivers are able to transmit and receive FSK data at any rate between 2.4 Kbps and 128 Kbps. Output power is 10 dBm (maximum). Receiving sensitivity is 𤩙 dBm. An on-chip frequency synthesizer ensures that the transceivers can handle multi-channel as well as frequency-hopping, spread-spectrum communications.
