... Ultra-Low-Noise Amplifiers FUNCTION Applications Information External Matching Components The MAX2640/MAX2641 are easy to use, generally requiring only five external components as shown in the Typical Operating Circuit. To reduce external compo- nent count further, replace external inductors with microstrip transmission lines. The high reverse isolation allows the tuning of the input matching network without affecting the output match, and vice versa ...
