How to use a Low Noise Amplifier
Posted by GPIO Labs on
Low Noise Amplifiers (LNAs) are designed to amplify signals such that they rise above the noise floor in radio systems. An increase in signal level relative to noise makes it easier to process the signal. This is the primary use case of an LNA. However, it is not the only application. For instance, an LNA can be used in transmitter systems or in general, systems where signal amplification is required. HOW SHOULD I CONNECT MY LNA? The RFin or RF input terminal of the LNA should always be connected to the source of the signal. In receiver systems, RFin should...
Use a FM Notch Filter to Improve the Performance of your Software-defined Radio
Posted by GPIO Labs on
FM radio is one of the most popular broadcast technologies out there. FM broadcast signals in most places in the world occupy the frequency range from 87.5 MHz to 108 MHz. These signals also happen to be very strong and overwhelm or saturate the receiver in a software-defined radio or RF receiver. This in turn impacts signal reception. You might for instance hear static instead of audio. If a user does not want to listen in to the FM broadcast band, then one way to mitigate the effect of this strong band of signals is to suppress or 'notch' them...
