Design a 100 MHz low-pass filter.
Meet a real specification, compare analytical and simulated results, then measure the hardware when you can.
PassbandS21 > −1 dB below 80 MHz
StopbandS21 < −20 dB at 200 MHz

THEORY

BUILD
VNA
Progress is demonstrated through calculations, designs, measurements, reviews and reproductions.
Real experiments
Claims carry evidence.
A measurement is more useful when the raw file, calibration, method, conditions and interpretation travel with the number.
Simulation
Backed by a reproducible model or circuit run.
Experimental
Supported by instrument data and measurement conditions.
Reproduced
Independently repeated by another member.
MAJAL × AoN
The simulator becomes the laboratory.
Open an exercise in MAJAL, test a design, verify engineering constraints and later publish or fork the result back into the community.
