Optimizing cascade gain stages in a communication system

A communication device comprising:

• a cascade gain device comprising at least a first gain stage and a second gain stage;
• an inter-stage matching network associated with the first gain stage;
• and
• an optimization unit coupled with the cascade gain device and the inter-stage matching network, the optimization unit operable to:
• determine a first noise figure and a first gain associated with the first gain stage of the cascade gain device;
• incrementally increase the first noise figure of the first gain stage by a plurality of noise figure increments, wherein the noise figure increments are determined based, at least in part, on a minimum noise figure and a maximum noise figure associated with the first gain stage;
• calculate, at each of the plurality of noise figure increments, at least a gain value that corresponds to the noise figure increment;
• select one of the plurality of noise figure increments and the corresponding gain value as an optimum noise figure of the first gain stage and an optimum gain value of the first gain stage respectively;
• and
• configure one or more parameters of the inter-stage matching network associated with the first gain stage based on the optimum noise figure of the first gain stage and the optimum gain of the first gain stage.

One or more machine-readable storage media having instructions stored therein, which when executed by one or more processors causes the one or more processors to perform operations that comprise:

• determining a first noise figure and a first gain associated with a first gain stage of a cascade gain device, wherein the cascade gain device comprises at least the first gain stage and a second gain stage;
• incrementally increasing the first noise figure of the first gain stage by a plurality of noise figure increments, wherein the noise figure increments are determined based, at least in part, on a minimum noise figure and a maximum noise figure associated with the first gain stage;
• at each of the plurality of noise figure increments, calculating at least a gain value that corresponds to the noise figure increment;
• selecting one of the plurality of noise figure increments and the corresponding gain value as an optimum noise figure of the first gain stage and an optimum gain value of the first gain stage respectively based on at least one of a cascade noise figure associated with the cascade gain device and a cascade gain value associated with the cascade gain device;
• and
• configuring one or more parameters of an inter-stage matching network associated with the first gain stage based on the optimum noise figure of the first gain stage and the optimum gain of the first gain stage
