Hi all,

I want to use the AD8314 with 5V instead of the nominal 3V that the datasheet uses for the graphs.

My question is if there is some variation in the output voltage or minimal error zone if I supply the IC with 5V

Thanks in advance

Santiago

Could you give me a advice?

the measurement　and　equation　is　not　match

Pleas give　me a advice?

Hello,

in AN-691 the AD8314 is precluded from use in low frequencies because of a series capacitor at the input.

Is this true for all frequencies below 100Mhz or is there a way to operate it at 15-65 Mhz?

Thanks

I am designing an RF level controller with the AD8314 Logarithmic RF Detector, using it's non-inverted output (V_UP, pin 6).

According to the datasheet, the loop filtering capacitor Cf should be placed between pin 4 (FLTR) and pin 6 (V_UP).

Maybe…

Hi,

I have a yagi antenna and I want to evaluate the radiation pattern by connecting the antenna to the AD8314 eval board and monitoring the signal strength on an oscilloscope.  The antenna characteristics are:

Frequency Range: 2400-2500 GHz

Gain…

Hi!

Can somebody provide me the S-parameter file for the input impedance of AD8314? The S-para files available in the AD forum is at 5V bias. I want it on 3.3V bias. Or somebody can just provide me the input impedance of 8314 at 150MHz and 3.3V.

Regards…

Hi all,

In the datasheet page 13, following is comment.

The video bandwidth is related to CF by

Video Bandwidth = 1 / 2 π × 13 kΩ × ( 3.5 pF + CF )

In the datasheet page 14, following is additional comment.

In practice, an improvement in loop dynamics…
