Title:
利得モードによる反射損失及び不整合が改善された増幅器
Document Type and Number:
Japanese Patent JP7386906
Kind Code:
B2
Abstract:
Disclosed herein are methods for use in operating signal amplifiers that provide impedance adjustments for different gain modes. The impedance adjustments are configured to result in a constant real impedance for an input signal at the amplifier. Some of the disclosed methods adjust impedance using switchable inductors to compensate for changes in impedance with changing gain modes. Some of the disclosed methods adjust a device size to compensate for changes in impedance with changing gain modes. By providing impedance adjustments, the amplifiers reduce losses and improve performance by improving impedance matching over a range of gain modes.
