Fully Distributed Tunable Bandpass Filter Based on Thin-Film Slow-Wave Structure
Figure 7
Measured and simulated S parameters of the 3 μm gap bandpass filter without bias voltage and with a 30 V polarization applied on each pole (corresponding to BST dielectric constant of 1000 and 400, resp., with dielectric loss of 0.04 for the values used in the full-wave simulations).
