ADM2485 Features

    The ADM2485 is a miniature transmitter module that generates on-off keyed (OOK) modulation from an exter- nal digital encoder (not included). The carrier frequency is quartz, surface-acoustic-wave (SAW) stabilized, and output harmonics are suppressed by a SAW filter. The result is excellent performance in a simple-to- use, surface-mount device with a low external component count. The ADM2485 is designed specifically for unlicensed remote-control and wireless security transmitters operating in the USA under FCC Part 15 and in Australia under DTC regulations.
