8. IF Amp Gain
The intended value is 75dB.
9. Waveform-Shaping Output Duty Cycle
The specified range of electrical characteristics is only available for single-tone.
10. Local Frequency Range (after multiplying frequency by 8)
When the multiplier circuit is used, the local frequency will be in the range 250.7 MHz to 439.3 MHz.
11. Treatment of FM Terminal when Using AM
When using AM, it is not necessary to treat the QUAD pin (pin 10). Leave it open or connected to an FM
external circuit. To use the bit rate filter, connect the RSSI pin (pin 21) to the bit rate filter through a
resistor. The AF-OUT pin (pin 22) should be left open.

Using AM causes current to flow through the AM/FM pin (pin 19). Ground the AM/FM pin (pin 19) or
connect it to the BS pin (pin 9).
