Results from measurements at lab exercises in Radio Electronics
Lab 2, the 21-22 of November 2013
This is a summary of S-parameter measurements made at BFR520 from Philips (IC = 5mA, VCE = 3V, Source Power = -35dBm). You may compare the results to the data sheet. S-parameters from the manufacturer are also found in the toolbox deslib0401/trdata for various quiescent points.
In hand-in assignment 2 you will use S-parameters that are a calculated mean value of all the groups.
These S-parameters are found in the file: SPAR13.S2P (option-click to download the file)
To solve hand-in assignment 2 you will also need noise parameters at 850MHz:
Fmin = 1.1 dB (=1.288), Gamma-opt=0.331, 47 deg, rn=0.260.
The result of each group are found below (NOTE, these files should NOT be used in hand-in assignment 2)
Lab groups: | Group 1 | Group 2 | Group 3 | Group 4 | Group 5 |
Group 6 | Group 7 | Group 8 | Group 9 |

According to the plots all measurements were successful. Congratulations, well done!
