Notes: 1. Current increases at higher RF input levels (>-20dBm and above)
2. For received signal with ±40kHz 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 (10kb/s version) or 3ms (64kb/s version) at maximum data rate.
