Isolator device with built-in power amplifier and embedded substrate capacitor

摘要

An isolator device with a built-in power amplifier includes a single dielectric multi-layered substrate, a high frequency power amplifier circuit, an isolator element, and circuit elements provided to the dielectric multi-layered substrate. The high frequency power amplifier circuit and the isolator element are connected with each other through the circuit elements and united with the single dielectric multi-layered substrate.
