AWR: DDS simulation
Hello Everyone,
Wish You All A Happy New Year. I have a simple problem that I am trying to simulate in Microwave Office. Since, I am a novice user of MWO and in general AWR, I appreciate some help in this regards. The problem goes likes this:
A DDS based Chirp Generator output (FMCW Liner Chirp) is mixed with a Sinusoidal signal. How do I model this in MWO? Since this is a mixed signal design problem, I was wondering whether firstly it is possible. If yes, what is the best way to do it? The specs are as follows:
(1) The DRO is used to generate a 7.129 GHz signal (sine wave)
(2) DDS chirp generator generates a chirp from 100 to 106 MHz
(3) Both the signals are mixed using a upconverter mixer.
I appreciate some suggestions or ideas to go about with this. I think I should be able to grab some Mixer design ideas from the tutorials, should get the sinusoid oscillator source from the library, the problem I guess would be the DDS chirp generator. Correct me if I am wrong.
Regards,
Shital
