Abstract

PURPOSE: To enable the full FET constitution with a miniature size by using the source follower circuit type FET featuring the input impedance of several KΩ as the impedance conversion means.
CONSTITUTION: The composite signal of in-phase and reverse phase is led out at frequency conversion means 51 by making local signal FL and RF signal FS pass through 90° -hybrid circuit 52 to be then rectified (55, 55') respectively. And the frequency conversion is given to the composite signal through FET13 and 13', and the IF signal is supplied to impedance conversion means 52. The input impedance of source follower circuit type FET56 and 56' features several KΩ at means 52, and the output impedance features a low level. As a result, a well matching is obtained with composite transformer 59, and thus the IF signal is transmitted to the coaxial cable. Transformer 59 is composed of the 180° -hybrod circuit which compounds the IF signals featuring the reverse phases each other in the in-phase.
