WebTraveling Wave Tube. Traveling Wave Tubes (abbr.: TWT, pronounced: “twit”) are vacuum tubes used as high-gain, low-noise, wide-bandwidth microwave wideband amplifiers.A TWT is capable of gains from 40 to 70 dB with bandwidths exceeding two octaves. ( A bandwidth of 1 octave is one in which the upper frequency is twice the lower frequency.) WebAMMAX3000+ 6-7MHz + 3-key LCD display 10W transmitter board. ... L and R signals.

In electromagnetics, an antenna's gain is a key performance parameter which combines the antenna's directivity and radiation efficiency. The term power gain has been deprecated by IEEE. In a transmitting antenna, the gain describes how well the antenna converts input power into radio waves headed in a specified direction. In a receiving antenna, the gain describes how well the ant… WebGraph of typical gain curves for “high gain” Yagi 18 element aerials.
