Integration’s IA4220 and IA4221 are single chip, low power, multi-channel FSK/OOK transmitters designed for use in applications requiring FCC or ETSI conformance for unlicensed use in the 315 MHz, 433 MHz, 868 MHz, and 915 MHz bands. The IA4220/21 are highly integrated, flexible, low-cost solutions that do not require production alignments. Used in conjunction with Integration’s IA4320 receiver, the IA4220/21 allow the user to build robust, low-cost RF data links. They are ideal for high-volume wireless applications, including remote control systems, home security and alarm systems, wireless keyboard/mouse and other PC peripherals, toys, and automotive applications, including remote keyless entry and tire pressure alert. Industrial applications like telemetry, personal/patient data logging, barcode readers, and automatic meter reading are also supported.
