Is my LT44 transformer suitable for audio (de)coupling?

Yes, but remember we are talking about scraping away at the last vestiges of the state of the art here. Optimum noise match varies over that range, and designing matching structures that keep the complex impedance of the waveguide transition at the exact conjugate of the input transistor noise match over such a bandwidth really is far from simple. By comparison audio is a breeze - I promise. d -- Pearce Consulting http://www.pearce.uk.com |
