DESCRIPTION

HopeRF's RAM01 is a highly-integrated, low power, multi-channel OOK receiver module designed for use in applications requiring FCC or ETSI conformance for unlicensed use in the 433, 868 and 915 MHz bands. Used in conjunction with HopeRF¡¯s transmitters, the RAM01 is a flexible, low cost, and highly integrated solution that does not require production alignments. All required RF functions are integrated.

The RAM01 has a completely integrated PLL for easy RF design, and its rapid settling time allows for fast frequency hopping, bypassing multipath fading, and interference to achieve robust wireless links. The PLL's high resolution allows the usage of multiple channels in any of the bands. The baseband bandwidth (BW) is programmable to accommodate various deviations, data rate. The module employs the low-IF approach; therefore, no external components are needed in a typical application. The RAM01 is a complete analog RF and baseband receiver, including a multi-band PLL synthesizer with an LNA, down converter mixers, baseband filters and amplifiers, and demodulator.

The module support Stand alone mode, that means it can receive data without MCU configuration. This mode mainly simplify the customer application complexity and can be replace traditional super- regenerative receiver and super-heterodyne receiver. but frequency can be selected.
