    The problem about the 2nd harmonics in RFMD RF3267

    Thanks dear BigBoss, 'Spurious Emission is different than harmonic level.Harmonic frequency ( 2nd Fo) does not fall down spurious mask of any digital scheme therefore its effect is generally not disturbing effect.' 1.Can i interpret your words as: if a this scheme works in 2GHz operating...

    The problem about the 2nd harmonics in RFMD RF3267

    Dear all, I am writing a report to explain every parameters of the specifications of a WCDMA chip RF3267. But i have a problem about the Harmonic Output (2fo) in its data sheet. The value is -15dBm under Pout +28dBm which converted to dBc is -43dBc. This is the...
