The Dual Band Pass Filters (DBPF) with high stop band rejection at center frequencies of 122 and 330 MHz are designed. The DBPF filters are fabricated in low temperature co-fired ceramic (LTCC) technology using a lumped element approach. Measured results show close agreement with simulations with very small form factor. The overall size of the dual band-pass filter is 32 mm x 18 mm x 2.2 mm.
