Method and system for adjusting replacement component characteristics

A method of adjusting a gain of an output from a replacement component in a system with plural components responsive to changing operating conditions so that a power level of an output from the system is approximately the same as a power level of an output from the system before installation of the replacement component, the method comprising the steps of:

• (a) storing in a system memory a relationship of gain to changing operating conditions for each of plural components in the system;
• (b) providing a replacement component for one of the plural components with a component memory for storing a relationship of gain to changing operating conditions for the replacement component;
• (c) providing the relationship stored in the component memory to the system memory when the replacement component is installed in the system;
• and
• (d) adjusting a control signal for the replacement component responsive to the relationships stored in the system memory so that the power level of the output from the system is substantially unchanged by installation of the replacement component.

A system for adjusting operating characteristics of a replacement component so that the operating characteristics of the replacement component approximate corresponding operating characteristics of a component replaced by the replacement component, the system comprising:

• a plurality of interactive components;
• a system memory for storing operating characteristics of each of said plurality of components;
• a replacement component with a component memory for storing operating characteristics of said replacement component, said replacement component for replacing one of said plurality of components;
• means for providing the operating characteristics of said replacement component from said component memory to said system memory when said replacement component replaces one of said plurality of components;
• and
• means for adjusting a control signal for operating said replacement component responsive to the operating characteristics of said replacement component so that said replacement component operating characteristics approximate those of the one of said plurality of components replaced by said replacement component.

An RF communication system for receiving an RF signal and converting the received signal to an intermediate frequency at a predetermined power level, the system comprising:

• a low noise coupler and an intermediate frequency amplifier connected in series, each having a gain that is responsive to a feedback voltage and which affects the predetermined power level;
• a system memory for storing a relationship of gain to an operating condition as a function of feedback voltage for each of said low noise coupler and said intermediate frequency amplifier;
• a replacement component with a component memory for storing a relationship of gain to an operating condition as a function of feedback voltage of said replacement component, said replacement component for replacing one of said low noise coupler and said intermediate frequency amplifier;
• means for providing said relationship stored in said component memory to said system memory when said replacement component is installed in the system;
• and
• means for adjusting the feedback voltage for said replacement component responsive to said relationships stored in said system memory so that the predetermined power level is substantially unchanged by installation of said replacement component.
