Overview
RF passive circuit simulation covers the electromagnetic analysis of filters, couplers, power dividers, resonators, and transmission line structures — extracting S-parameters, insertion loss, and spurious response characteristics for microwave and mmWave applications. Accurate EM modelling of planar, waveguide, and 3D RF structures ensures that resonance, coupling, and Q-factor predictions match manufactured performance, reducing the design iteration cycles needed to meet system gain and noise figure budgets.

Key Aspects
Designing bandpass, bandstop, and low-pass filters in microstrip, stripline, or waveguide — optimising element values and layout for target passband ripple, return loss, and stopband rejection.
Computing coupling and isolation of directional couplers, power dividers, and hybrids — validating amplitude and phase balance across the operational bandwidth.
Accurately predicting the loaded and unloaded Q-factor of cavity, dielectric, and planar resonators — critical for oscillator phase noise and filter insertion loss.
Identifying spurious resonances and harmonics that degrade filter out-of-band rejection — guiding layout modifications to push spurs outside the operating band.
