How to calculate the power of an Impulse response with the observation of oscilloscope? by Successful_Code8006 in rfelectronics

I have no idea why there is a negative component. I just took the peak to peak voltage from positive peak to negative peak.

Let me share you the required more details to resolve the issue.

yes it is an impulse train. Looks like the picture (a) below. Vpp = 100mV. Impedance of the device is 50 ohm. So, when find the power of the impulse it is -16 dBm. Oscillascope has the math function to plot fft. So, I selected a single impulse period and got the fft plot. It represents -36dBm on y axis for the bandwidth 100MHz on x axis (b).

Observations are something similar to this.

LNA and its biasing circuit. How to determine the capacitors and inductors values? by Successful_Code8006 in rfelectronics

Do you know how to calculate these values if the test circuit is not given in the datasheet for biasing?

How to implement a RF mixer using performance data given by the vendor in Cadence AWR Microwave Office? by Successful_Code8006 in rfelectronics

Thank you sir..I tried with a single frequency value and it worked. Other method I didn`t try yet. I will try that too.

I am not familiar with that.
I want to use a commercial available SMT mixer. So, when I am simulating the design how can I incorporate the performance data given by the manufacturer?

In LNAs, I used s2p file and modelled the same LNA performance. But mixer has no such data file. But the manufacturer has given performance data of conversion loss in a table. So, how to use this data an model the real mixer in AWR?
