DESCRIPTION: The 3-2000519 and 3-2000519A modules are fully programmable multichannel PLL based FSK transceivers, with dual IF conversion and software channel selection in the 868 Mhz (p.n. 3-2000519A) and the 433 Mhz (p.n. 3-2000519) ISM bands. The typical transmission output power is 10 mW ( +10 dBm ) and the sensitivity in receive mode is –108 dBm. The dual IF conversion, together with the SAW front end filter, allows for a highly selective module, with outstanding side channel noise immunity, ideal for industrial applications and wireless RS232 and RS485 replacement.
