A FET amplifier in finline technique

The successful design and realization of a stable FET amplifier using the finline technique are presented. The circuit has been realized in integrated E-plane technology and features an input and output port in unilateral finline and a combined microstrip/coplanar bias circuit. The amplifier has been designed for 17-GHz operation and has a gain of 6 dB over a bandwidth of 1 GHz using a NE67300 FET. >
