1GHz Hairpin BPF design
In this article, 1GHz Hairpin type of BPF(Band Pass Filter) design is explained. One can use Agilent ADS or Microwave Office as RF design software tool for simulation and verifying the results. The layout is automatically created.
RF Simulation Circuit
The figure depicts RF simulation circuit for 1GHz Hairpin BPF.
| Substrate Specifications | Value |
|---|---|
| Relative Dielectric Constant(εr) | 3.38 |
| Substrate thickness(H) | 0.8128 mm |
| Conductor thickness(T) | 0.035 mm |
| Rho(Metal Bulk resistivity normalized to gold) | 0.7 |
| Tand(Loss tangent of dielectric) | 0.0027 |
Results
As shown in the figure S21 (insertion loss) is about 0 dB. Here at RF frequency of 1GHz, insertion loss of BPF (Band Pass Filter) is about -2dB. Return loss of this filter (S11) is about -17dB.

Conclusion
As explained here any other RF filter of hairpin or interdigital type can be designed and simulated.
