This article proposes a miniature embedded multilayer interdigital bandpass filter (BPF) based on low temperature co-fired ceramic (LTCC) technology, which is used to suppress fundamental and harmonic components of local-oscillator signal in a LTCC transceiver module. A practical design methodology corresponding to LTCC multilayer configuration is described. A five-order Chebyshev interdigital BPF is developed and verified by full-wave simulation. The proposed filter is fabricated using multilayer LTCC technology and measured using vector network analyzer. Good agreement between simulated and measured response is observed. Covering area of the fabricated BPF is only 8.1 X 7.4 mm(2) (including via fences).
