Product Summary

The NRF905 is a Single chip Transceiver. It consists of a fully integrated frequency synthesizer, receiver chain with demodulator, a power amplifier, a crystal oscillator and, a modulator. The applications of the NRF905 are Wireless data communication, Alarm and security system, Home automation, Remote control, Surveillance, Automotive, Telemetry, Keyless entry, Toys. Current consumption is very low, in transmit only 9mA at an output power of -10dBm, and in receive mode 12.5mA. Built-in power down modes makes power saving easily realizable.
