Data Sheet

Note:
[1] Unless otherwise noted, the modulation source is sine. The temperature range is from 20
℃
to 30
℃
, carrier frequency ≥ 1 MHz.
[2] The envelop peak power is no greater than the maximum value of the specication output range.
[3] External modulation, measured at 100 kHz deviation.
[4] External modulation, measured at 5 rad deviation.
[5] The parameter is measured under room temperature. When the temperature is different from the room temperature, the
specication will deteriorate.
[6] Baseband frequency ≤ 10 MHz.
[7] Load from the ash of the internal non-volatile memory.
