Highly compact lumped element resonators in LTCC for avionic systems

A new system level architecture for multi-standard receivers to cover all the VHF and UHF band avionic systems is proposed. The proposed architecture relies on special RF front-end filtering to separate different services. A dual band-pass filter is designed using only two resonators. The resonators are designed and fabricated in LTCC technology using a lumped element approach. Measured results show close agreement with simulations with very small form factor.
