In this regard, an antenna matching network may be configured to maximize received signal strength for a determined frequency and an amplifier gain may be adjusted based on the maximized signal strength such that output levels of the amplifier are between specified limits. The antenna matching network may be programmatically controlled via one or more switching elements. The amplifier gain may be programmatically controlled via one or more bias points. The antenna matching network may be configured for a plurality of frequencies in a frequency band, such as an FM broadcast band, and a configuration for each frequency may be stored. Accordingly, when the receiver is tuned to a frequency, a corresponding configuration may be retrieved from memory."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamic impedance matching with LNA","description":"Aspects of a method and system for LNA adjustment to compensate for dynamic impedance matching are provided.
