In this paper, compact and high order on-chip wideband bandpass filters (BPFs) are proposed in the gallium arsenide (GaAs)-based integrated passive device (IPD) technology. The design utilizes a stepped-impedance multimode resonator to achieve a bandwidth of more than five octaves, with a high rejection to higher-order frequencies in the passband. The use of Metal-Insulator-Metal (MIM) capacitors and spiral inductors allows for a very small chip size. The paper also presents equivalent circuit models and design equations, and demonstrates the performance of a fabricated fourth-order prototype.
In this letter, compact, high order on-chip wideband bandpass filters (BPFs) are proposed in the gallium arsenide (GaAs)-based integrated passive device (IPD) technology. The design employs a stepped-impedance multimode resonator and achieves a bandwidth of more than five octaves with a high rejection to fourth/fifth-order of the passband. A very small chip size is realized by implementing Metal-Insulator-Metal (MIM) capacitors and spiral inductors. Meanwhile, the equivalent circuit models and design equations are presented. A fabricated fourth-order prototype showed a low insertion loss of 1.2 dB, a 3-dB fractional bandwidth of 143%, and a upper stopband attenuation of more than 44 dB extending to higher than 30 GHz (>10 f(0)). The filter size is 2.16 mm x 0.90 mm, which is only about 0.02 lambda(0) x 0.01 lambda(0) at f(0) = 3 GHz. To our knowledge, this is the widest BPF with the smallest circuit size ever published.
