Replace ideal components with physical microstrip models (like MLIN for lines and MTEE for junctions). Use the controller to automate tuning. Define your goals (e.g.,
Analyzing phase noise and oscillation conditions for frequency synthesis.

Arjun stared at the messy waveform on his lab monitor. As a junior engineer at a satellite startup, he had been tasked with designing a Low Noise Amplifier (LNA)
Build the structure using MCPL (microstrip coupled lines) elements. Because analytical equations for closely spaced coupled edges lose precision at high frequencies, rely heavily on Momentum EM optimizations to fine-tune the pole spacing, ensuring flat passband insertion loss and steep out-of-band rejection. B. Low Noise Amplifier (LNA) Design
At frequencies above 1 GHz, component dimensions become comparable to the signal wavelength. This results in transmission line effects, phase shifts, and signal attenuation that must be accounted for. This results in transmission line effects
ADS offers powerful simulation engines to validate the design.
Design coupled-line filters or Lange couplers using microstrip transmission lines.
