Description
The AMMC-5026 is a broadband PHEMT GaAs MMIC
Traveling Wave Amplifier (TWA) designed for medium
output power and high gain over the full 2 GHz to 35 GHz
frequency range. The design employs a 6-section cascode
connected FET structure to provide flat gain and medium
power as well as uniform group delay. For improved reli-
ability and moisture protection, the die is passivated at
the active areas.
