Stacked Crystal Filters (SCFs) are used in Bandpass filters and other applications where frequency control is required. SCFs use the Solidly Mounted Resonator (SMR) structure to enable operations at RF frequencies, typically 1–5 GHz. In the response spectrum of the SCFs, besides the main resonance mode, there are some unwanted additional modes(More)
Low Noise Amplifiers (LNAs) amplify weak signals received by the antenna in communication systems. Every wireless system module typically consists of one or several LNAs. Applications include GPS receivers, wireless data systems, satellite communication, cellular handsets, radio systems, etc. The low noise in the receive chain is reduced by the gain of the(More)
