DESCRIPTION

HopeRF’s RA01 is a single chip, low power,

multi-channel OOK receiver 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

RA01 is a flexible, low cost, and highly integrated

solution that does not require production alignments.

All required RF functions are integrated. Only an

external crystal and few capacitors are needed for

operation.

The RA01 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 deviation, data rate, and crystal tolerance

requirements. The receiver employs the low-IF

approach; therefore, no external components (except

crystal and filtering capacitors) are needed in a typical

application. The RA01 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 chip dramatically reduces the load on the

microcontroller with integrated digital data processing:

data filtering, clock recovery, data pattern recognition

and integrated FIFO. To minimize the system cost, the

chip can provide a clock signal for the microcontroller,

avoiding the need for two crystals.
