Notes:

1. The specifications in Table 3 are guaranteed at a supply voltage of 3.6 VDC and Ta = 25 °C.

2. All PEP specifications are for two input sinusoids at 2440 MHz and 2450 MHz. PEP is calculated from the average power assuming a

peak-to-average ratio of 3 dB. Output power loss due to the recommended output-matching network is included in the values in Table 3.

3. Input PEP = –3 dBm (differential). (Under this condition, RF110 output power is compressing. The output peak-to-average ratio is

approximately 2 dB.)

4. Single sinusoidal input.

5. Input PEP = –15 dBm (differential).

6. Input PEP = –25 dBm (differential).

7. When ENABLE (pin 7) is low.
