QCan the ADL5511 be used for envelope detection in HPA and LPA applications?
AYes, the ADL5511 has an envelope bandwidth of 130 MHz and a power detection
range of 40 dB. This makes it feasible for this device to accurately detect
the envelope of a modulated carrier with deep envelope modulation. In a
so-called "drain modulation" application, the signal from the envelope output
of this detector would be used to drive a fast switching power supply which
would in turn drive the collector or drain of a power transistor.
