Certain aspects of a method and system for dynamically adjusting intermediate frequency (IF) and filtering in microwave circuits may include generating one or more intermediate frequency (IF) signals from one or more baseband signals and/or one or more radio frequency (RF) signals. The generated one or more IF signals may be filtered to avoid detected interference and/or detected noise from out-of-band radio sources. The frequency of the generated one or more IF signals may vary depending on the detected interference and/or detected noise. The filtering of the generated one or more IF signals may be adjusted based on the variation in the frequency of the generated one or more IF signals. The one or more RF signals may be down-converted to generate the one or more IF signals. The generated IF signals may be further down-converted and dynamically filtered to generate the desired baseband signals.
