Product Summary

The NRF2402 is a single-chip radio transmitter for the world wide 2.4 - 2.5 GHz ISM band. The transmitter of the NRF2402 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 Shock Burst and Power Down modes make power saving easily realizable. The applications fo the NRF2402 include: Wireless mouse, keyboard, joystick, Keyless entry, Wireless data communication, Alarm and security systems, Home Automation, Remote control, Surveillance, Automotive, Telemetry, Intelligent sports equipment, Industrial sensors, Toys.
