GENERAL DESCRIPTION
KEY PRODUCT FEATURES
The RF69 is a highly integrated RF transceiver capable of
operation over a wide frequency range, including the 433,
868 and 915 MHz license-free ISM (Industry Scientific and
Medical) frequency bands. Its highly integrated architecture
allows for a minimum of external components whilst
maintaining maximum design flexibility. All major RF
communication parameters are programmable and most of
+20 dBm - 100 mW Power Output Capability
High Sensitivity: down to -120 dBm at 1.2 kbps
High Selectivity: 16-tap FIR Channel Filter
Bullet-proof front end: IIP3 = -18 dBm, IIP2 = +35 dBm,80
dB Blocking Immunity, no Image Frequency response
them can be dynamically set. The RF69 offers the
unique advantage of programmable narrow-band and wide-
band communication modes without the need to modify
external components. The RF69 is optimized for low power
Low current: Rx = 16 mA, 100nA register retention
Programmable Pout: -18 to +20 dBm in 1dB steps
Constant RF performance over voltage range of chip
consumption while offering high RF output power and FSK Bit rates up to 300 kb/s
channelized operation. TrueRFtechnology enables a low-
cost external component count (elimination of the SAW
Fully integrated synthesizer with a resolution of 61 Hz
filter) whilst still satisfying ETSI and FCC regulations.

2. Electrical Characteristics
2.1. ESD Notice
The RF69 is a high performance radio frequency device. It satisfies:
Class 2 of the JEDEC standard JESD22-A114-B (Human Body Model) on all pins.
Class B of the JEDEC standard JESD22-A115-A (Machine Model) on all pins.
Class IV of the JEDEC standard JESD22-C101C (Charged Device Model) on pins 2-3-21-23-24, Class III on all other
pins.
It should thus be handled with all the necessary ESD precautions to avoid any permanent damage.
2.2. Absolute Maximum Ratings
Stresses above the values listed below may cause permanent device failure. Exposure to absolute maximum ratings for
extended periods may affect device reliability.
