Usable band is determined by local regulations

Maximum output power with 0dBm output power setting. Antenna load impedance = 15Ω +j88Ω

Time of maximum Tx only current is typical 300µs and maximum 350µs

Time of maximum current consumption in RX is typical 500µs and maximum 1ms

Transmit only operation provides no ANT channel management across the air channel and is not recommended for

normal operation

Asynchronous serial messages contained two 0 pad bytes, thereby adding to the average current. Values will be

lower without the use of 0 pad bytes

Does not include base current. See current calculation examples below

Value calculated assuming that external 32.768 kHz crystal oscillator is used

Example Current Calculations:

1. Transmit channel with Broadcast data at 4Hz with a bit synchronous serial interface and external source

of 32.768kHZ clock.
