NOTE: Use the Project Report Template and keep answers to questions on consecutive sheets of paper with all plots at the end.
IN NO CASE may code or files be exchanged between students, and each student must answer the questions themselves and do their own plots, NO COPYING of any sort! Nevertheless, students are encouraged to collaborate in the lab session.
Only turn in requested plots ( Pxx ) and requested answers to questions ( Qxx ).
Print this single plot and turn it in. ( P3 )
Save a snapshot of this single plot as above and turn it in. ( P4 )
Use an excel spreadsheet (amp3.xls)
to calculate gain, Noise Figure in dB, 1dB compression (P1dB
in dBm), and output intercept point (OIP3 in dBm) of the
entire radio, and turn in this spreadsheet. (Q6-Q11 )
The spreadsheet results should match your simulation. If the
1 dB compression point is not given for a component, then
use Psat (saturation power level) as an approximate 1 dB
compression point.
Save a copy of the schematic in a differently named file.
In this new schematic file, delete
the back end of the radio (mixer through IF filter)
and connect the output "term" to the output of the second
preselector. Sweep the "front end of the radio from 50 to 150 MHz and plot S21. Do
not plot unreasonable ranges
of dB for the y-axis, rarely would you ever exceed a 120 dB
range. Plot this and turn it in. (P5 )
Report
NOTE ReportTemplate: Use the Project Report Template and keep answers to questions on consecutive sheets of paper with all plots at the end.
Do not add extraneous pages or put explanations on separate pages unless specifically directed to do so. The instructor will not read extraneous pages!
Only turn in requested plots (Pxx ) and requested answers to questions (Qxx ). All plots must be labeled P1, P2, etc. and all questions must be numbered Q1, Q2, etc. YOU MUST ADD CAPTIONS AND FIGURE NUMBERS TO ALL FIGURES!!
