EERF6395 Homework Set – VSS Project Simulations Note: show all responses in dB or dBm. Unless specified below use the default values in the VSS behavioral models. 1. Create a simple test circuit to observe the spectrum of a single RF tone at f = 2 GHz with P = 10 dBm. (use “complex” tone for the node setting) System used: TONE ID=A1 FRQ={ 2,2.1 } GHz PWR=10 dBm PHS=0 Deg CTRFRQ= SMPFRQ= ZS=_Z0 Ohm T=_TAMB DegK NOISE=Auto PNMASK= PNOISE=No phase noise SPwr: 13.0103 dBm TP ID=TP1 AMP_B ID=A2 GAIN=10 dB P1DB=20 dBm IP3= IP2= MEASREF= OPSAT= NF=3 dB NOISE=Auto RFIFRQ= SPwr: 21.3297 dBm TP ID=TP2 a) observe power spectrum at a test point at the output of the source

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
