The meaning of these values is explained all kinds of other areas, so we won't focus on it, however the formulas are incorporated below for ease, the place all values are in dBm or dBc and PO refers to the output electrical power of 1 of the specified tones:

Volume is definitely the single most important factor in the price of an amplifier. Intricate multi-chip modules is often developed for the handful of pounds, though even fundamental customized types can Expense several thousands of bucks, mainly because of the economics of quantity output. Amplifier need major investment decision to style and design and qualify from a trustworthiness standpoint. The tooling Price tag of producing these amplifiers (dominated by mask costs) is not less than six figures (in 2020 US dollars), and might be around $1M for silicon types.

What do these nonlinearities appear like around the sign in time domain? This relies on a lot of factors, together with simply how much bandwidth the amplifier supports. An ideal broadband amplifier will saturate simply by clipping from the finishes with the output signals, but this results in a fast transition that needs greater order harmonics being supported.
