The BP35A7A is a ceramic-based RF matching circuit produced by the Japanese electronics manufacturer ROHM. It is a surface-mount, single-piece component that is designed to provide impedance matching when integrated into radio frequency (RF) power amplifiers. It is commonly used for applications operating in the frequency range of 0.1 to 6GHz. The BP35A7A provides a maximum of 40dB of isolation, making it suitable for in-building wireless systems and other RF applications. The component has an insertion loss of 0.2dB and requires an input voltage of 1.8 to 5.5V. It is RoHS compliant and has an operating temperature range of -40 to +85°C.
