What are Low Phase Noise Amplifiers (LPNAs)?
In modern digital communications and radar the success of communications and sensing has become extremely sensitive to phase noise as well as amplitude noise. Phase noise is the frequency domain description for jitter, which is a major component of bit-error rate (BER) and other phase error related digital communication and sensing degrading phenomenon. Where Low Noise Amplifiers (LNAs) are...
What is a LNA (Low Noise Amplifier)
There are many cases in RF circuit design where there is a need to increase the power of a signal while avoiding adding any signal degrading characteristics. An example of this is when a mixer needs to be driven at a certain input power beyond what is available from the baseband transceiver components. Another example is increasing the signal strength of a relatively weak signal received by an...
