Abstract
Low-noise amplifier (LNA) filters and processes for filtering global navigation satellite system (GNSS) signals are disclosed. The LNA filters can be used to down-convert a received GNSS signal to a lower frequency, filter the GNSS signal at the lower frequency, and up-convert the GNSS signal to the original frequency of the GNSS signal. The down-converted frequency can be selected based on a temperature of the GNSS signal to compensate for shifts in the frequency response of the filter due to temperature changes.
