Low Phase Noise Amplifiers
-
Low Phase Noise amplifiers are critical for many applications requiring high signal integrity. This is especially relevant in instrumentation, defense, and telecommunication applications where low phase noise amplifiers are becoming increasingly important as the oscillators improve. Phase noise is described as the close-in noise to the carrier that can often appear as jitter on a clock signal. Analog Devices offers a large portfolio of low phase noise amplifiers to meet a variety of requirements in the LO network, receiver, as well as in the transmitter. Our portfolio supports a wide range of power levels and frequencies to provide the right solution for the given application.
