RF02 Universal ISM Band

FSK Transmitter

RF02

DESCRIPTION

Hope’s RF02 is a single chip, low power, multi-channel

FSK transmitter 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 RF01, Hope’s

FSK receiver, the RF02 transmitter produces 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 bypass filtering are

needed for operation. The RF02 offering a higher output

power and an improved phase noise characteristic.

The RF02 features 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. In addition, highly stable and accurate FSK modulation is

accomplished by direct closed-loop modulation with bit rates up to 115.2 kbps. The PLL’s high resolution

allows the use of multiple channels in any of the bands.

The integrated power amplifier of the transmitter has an open-collector differential output that directly

drive a loop antenna with programmable output level. No additional matching network is required. An

automatic antenna tuning circuit is built in to avoid costly trimming procedures and de-tuning due to the

“hand effect”.

For low-power applications, the device supports automatic activation from sleep mode. Active mode

can be initiated by several wake-up events (on-chip timer timeout, low supply voltage detection).
