Abstract

There is disclosed a hybrid circuit in which a circuit formed by TFTs is integrated with an RF filter. The TFTs are fabricated on a quartz substrate. A ceramic filter forming the RF filter is fabricated on another substrate. Terminals extend through the quartz substrate. The TFTs are connected with the ceramic filter via the terminals. Thus, an RF module is constructed.
