We use the weak directional coupler to attenuate the power signal when we use AD8362 to measure the larger power. In 500 Mhz-900 Mhz frequency band, the coupling of weak directional coupler is positively correlated with frequency, and the coupling degree…
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 measure the rms power level of such signals?
I reference the circuit of page 21 in the AD8348 PDF document,
I use the AD8362 control the the ADRF6850 conduct AGC.
See also the circuit of page 27 in the AD8362 PDF document.
You see it?
There is good description of a typical calibration process on page 24 of the ADL5906 datasheet (rev A). It's called System Calibration and Error Calculation. ADL5906 and AD8362 are functionally almost identical so the equations described in there…
Do you have any information on the Gain Control Bandwidth of the AD8362's output op-amp? I want to use the AD8362 in Controller Mode and want to factor this bandwidth into my loop calculations.
Is the output of the AD9951 buffered? This is a current out DAC whose voltage is formed by the load resistance. If the AD8362 circuit is connected directly to the AD9951 then the DAC will see a lower load which will give lower voltage.
One way of checking…
I have a design that is using the TMP36 to compensate for temperature changes of the AD8362 Log Amp. The input to the AD8362 is 1 MHz. The chart in the application note only goes down to 900 MHz when selecting the resisters shown in the application. How…
