Notes: 1. Current increases at higher RF input levels (-20dBm and above).
2. For received signal with ±30kHz FM deviation.
3. Typical figures are for signal at centre frequency, max. figures are for ±50kHz offset.
4. For 50:50 mark to space ratio (i.e. square wave).
5. Average over 30ms (10kbps version) or 3ms (64kbps version) at maximum data rate.
