AbstractHybrid cryogenic low-noise amplifiers are often enclosed in a metallic housing with several bias channels. Strict machining tolerance is necessary for solid clamping of the lid to avoid degradation in performance. A new packaging is proposed by applying photonic bandgap (PBG) structures; which greatly relaxes the tolerance on clamping' results in natural bias channels' suppresses higher order modes' and creates wide open access for assembly.
