AD8363: Part-to-Part variation

Question What is the expected spread from chip to chip for the slope and offset parameters of this power detector? We see a spread of more than 5 dB from chipto chip when measuring power and applying a…
AD8363: Using INHI vs. INLO for Wideband Applications

Q. The AD8363 datasheet recommend driving the RF input through INHI for frequencies at or below 2.7 GHz and through INLO for operation above 2.7 GHz. If I have an application where I want one circuit to…
ADL5902 RMS Detector Output Voltage Clamping for High Input Power Levels

Q. At high input power levels (above 0 dBm), the output voltage of the ADL5902 rms detectors (and some other rms detectors also) loses linearity and clamps to the rail. What causes this and is there…
Alternatives to AD8362 High Range RF RMS Detector

Q. I have used the AD8362 logarithmic detector in the past. Now I am starting a new design and am wondering if there are any newer alternatives. ---------------------------------------------------…
Can the AD8362 Logarithmic RMS Detector accurately WiMax and LTE?

Q. I am looking for an RMS detector which will measure WiMax and LTE signals (OFDM Modulation). Looking at the data sheet of the AD8362, I see no mention of these standards. Can the AD8362 accurately…
Operating the AD8362 Evaluation Board at Low Frequencies

Q. I am having some problems getting the AD8362 evaluation board to work low frequencies (e.g. around 1-10 MHz). Do I need to make some changes to the evaluation board for operation in this frequency…
Operating the AD8364 dual RMS Detector at frequencies below 450 MHz

Q. The AD8364 datasheet provides specification data down to 450 MHz but says that operation down to "Low Frequencies" is possible. Do you have any advice on operating this device below 450 MHz. --…
Reducing the Response Time of an RMS Detector

Q. As I increase the value of the AD8362 filtering capacitor, the device's fall time after an RF burst has decayed becomes very long. How can I get around this? ---------------------------------…
S-Paramters for a RMS-responding RF Detectors

Question : Are S-Parameters available rms-responding RF detectors such as AD8362 or ADL5902? Or is there some kind of a behavioral model available for these devices. Answer : We do not publish s-parameters…
