Notes:
1. Available in 25kHz channel steps on other custom frequencies in the 27MHz band
2. Measured into 50Ω resistive load.
3. Total over full supply and temperature range.
4. With 0V – 3.0V modulation input.
5. To achieve specified FM deviation.
6. For 1V_pk-pk signal biased at 1.4V
7. Complies with spurious emission limits of ETSI EN 300 220-1
8. For use in USA, Australia, NZ and only for model control in Europe.
The 100mW version is limited to 9v or 25% duty cycle
