Latest Patents

Tateishi holds a patent for an "Antenna amplifier and shared antenna amplifier." The primary objective of this invention is to receive weak signals with high sensitivity while minimizing distortion and signal suppression in the presence of strong interference signals. The design includes a switch circuit that transitions from the output of an amplifier to a through-circuit when high-frequency signals are received. This through-circuit allows the high-frequency signal to be directed to the output without passing through the amplifier, thereby enhancing performance. The switching operation is based on low-frequency components that correlate with distortion, allowing for more effective signal management. Additionally, the invention incorporates a smoothing process to reduce noise and utilizes an inverting amplifier to prevent oscillation.
