Abstract
In this letter, a compact bandpass filter (BPF) using integrated passive device (IPD) technology is presented, which is based on a pair of coupled-line inductors. To analyze the principle of this design, a simple but effective equivalent circuit model is provided. Using this model, it is easy to increase the number of resonators order. This structure is implemented by using a Si-based IPD process in which line inductors are located on a thick laminated organic (H = 40,μ with a ground metal for shielding of lossy silicon. The minimum insertion loss of two-resonator BPF is 1.1 dB, and cascaded two-resonator structure is 2.3 dB. The size of two-resonator and cascaded two-resonator BPFs, excluding the pads, are only 0.246 × 0.44 mm and 0.492 × 0.88 mm, respectively.
