A Feedfoward Gain Block (1983)

By G. Luettgenau and J. Powell, TRW Semiconductors, Inc.

This paper describes the characteristics and in-system performance of a compact feed-forward gain block which is applied in much the same way as conventional hybrids.

The feed-forward approach toward increased linearity and output capability yields a high return on an investment in cost and power consumption.

Detailed analyses are performed with respect to trunking, distribution and general system upgrading. Operation with various degrees of tilt and output level is evaluated.

The feasibility of combining feed-forward blocks with normal hybrids is discussed. The data presented allow the system designer to make performance and cost comparisons with alternate approaches.

In conclusion, mechanical and thermal aspects are discussed. A prognosis for future developments in the area of integrated feed-forward amplifiers is given.
