Hi there,
0.1 Hz is so low that analog diode detectors will probably not work well, due to leakage. Perhaps consider a mixed-signal approach. An ADC to sample the waveform, then DSP or MCU firmware to digitally detect and hold the peak value for however…
Hi trecb,
100 Ohm is the minimum resistor value of external loading. Higher resistor values approaching infinity are fine, or no resistor is OK. The output is low-impedance, thanks to the on-chip buffer amplifier. If loaded with 200 Ohms, current consumption…
Hi (Bruce?),
As I was previously working with an AD8302 gain/phase detector for a Scalar Network Analyzer, which for me has a redundant phase detection so I spent some time looking at other log amps for my V2.0 PCB. I came across the AD8307 and newer…
Hi,
I used AD8310 as a detector, and converted the detected voltage to the desired voltage range through the invert phase scale converter circuit. However, when I connected the output of the detector to the invert phase scale converter circuit, undesirable…
Hi rookie1,
For AD8310 low frequency use, there are 3 places that need bigger capacitors:
1) input coupling capacitors.
2) DC offset cancellation capacitor.
3) output filter capacitor.
For 1), the schematics above already shows large capacitors here.
Hello Everyone,
I am going to use an AD8310 for measuring the RF power to my system. The RF is pulsed with a duty cycle of 1:10 or even lower. When an RF signal is at the input of the AD8310 there is no problem and the output voltage is as expected. But…
Dear sirs,
i need to measure forward power and i'd like to usse a directional bridge the way is described in Analog Dialogue 52-05 may 2018 (An integrated bridge with dual RMS detectors for RF power and return loss measurement). I designed a resistor…
Hi, recently our customer testing AD8310.Through X light, we can find that there is a surplus near the pin.Is the chip‘s pin status is good？What’s the AD8310 PIN Componet?Thanks.
Hello. I am using the AD8310 to measure signals from 10kHz to 1MHz. The signals I am measuring are CML (about 600mV peak-to-peak). When the stimulus is applied to the AD8310 the output overshoots and takes an extremely long time to settle. My schematic…
Concerning with the post "Question for AD8310 ",does the intercept deviation link to the noise floor in the variability between devices?For example, the intercept increases then the noise floor decreases andthe intercept decreases then…
