Latest Patents

One of Sato's latest patents is a power amplifier circuit. This circuit includes a first transistor disposed on a semiconductor substrate, and a second transistor that supplies a bias current based on a first current, which is a part of a control current to the first transistor. Additionally, it features a current output element where the current flowing through it increases with a rise in temperature. The wiring portion consists of multiple metal layers that are electrically connected to the emitter of the first transistor and are stacked to oppose the semiconductor substrate. Notably, at least one metal layer among these extends to overlap an area from the first disposition area of the first transistor to the second disposition area of the current output element in the plan view of the semiconductor substrate.

Another significant patent is a power amplifying module. This module includes a first input terminal, a second input terminal, a first power amplifier, a stage matching circuit, a bypass line, and a second power amplifier. The first input terminal receives a first input signal in a first operation mode, while the second input terminal receives a second input signal in a different operation mode. The first power amplifier amplifies the first input signal and outputs a first amplified signal. The stage matching circuit, located downstream of the first power amplifier, receives this amplified signal. The bypass line allows the second input signal to enter the stage matching circuit without passing through the first power amplifier. Finally, the second power amplifier amplifies either the first amplified signal or the second input signal, outputting a second amplified signal.
