NRF2402G

PRODUCT SPECIFICATION Single chip 2.4 GHz Transmitter nRF2402 FEATURES APPLICATIONS True single chip GFSK transmitter in a Wireless mouse, keyboard, joystick small 16-pin package (QFN16 4x4) Keyless entry Adjustable output power up to 0dBm Wireless data communication Data rate 0 to 1Mbps Alarm and security systems Low Bill of Material Home Automation Remote control Multi Channel operation Surveillance 128 channels Automotive Support frequency hopping Telemetry Channel switching time <200 s. Power supply range: 1.9 to 3.6 V Intelligent sports equipment CRC computation Industrial sensors ShockBurst mode for ultra-low power Toys operation Low supply current, typical 10mA peak -5dBm output power 100% RF tested World wide use GENERAL DESCRIPTION nRF2402 is a single-chip radio transmitter for the world wide 2.4 - 2.5 GHz ISM band. The transmitter consists of a fully integrated frequency synthesizer, a power amplifier, a crystal oscillator and a modulator. Output power and frequency channel is easily programmable by use of the 3-wire interface. Current consumption is very low, only 10 mA at an output power of -5dBm. Built-in ShockBurst and Power Down modes make power saving easily realizable.
