Q
What is the input impedance of AD8307?
A
We don't specify the input impedence directly, but as it is an input to anoperational Amplifier, its in the Mohm range. More significant is the input
bias current which for the AD8607 ( for…
Hi,
I am not an expert in RF; I am trying to design a signal power meter for satellite application using AD8307 log Amp.
Below is the schematic that uses BPF (BPF-C70+) to filter unwanted signals and to allow only 70MHz signals. I am able to see the 70Mhz…
Hii,
we are using AD8307 Detector to detect Power level from -75dBm to +10dBm,while we are doing testing we had observed that detector output voltage is changing without changing the input power level from day to day.
kindly address to problem and provide…
Hi,
I am trying to use AD8307/AD8310 (I tried both on different boards) to detect the shape of 50-400us pulses (DC pulse). I am using the chips in DC connected configuration, signal placed at the bias voltage advertised in the datasheet (3.1V for 5V supply…
Greetings Jim,
Sorry about the delayed response to your inquiry. I'm just now getting the notification. Perhaps there was some system delay at this end.
About your AD8307 circuit: The circuit in the PDF looks good to me. These types of simple circuits…
Hello all,
For a particular case, I'm looking for S Parameters (S11 actually) of AD8307 in mixed mode to have an overview of the input impedance in differential mode driving.
Is it possible to have a touchstone file with S11 in this way?
Thank you…
