TH-3 Microwave Radio System: Networks

This paper describes the essential features and the performance of the AR6A microwave transmitter and receiver. Subsystems that are major contributors to repeater noise are explained in detail. Design objectives for each of these units are given and compared to typical results obtained from measurements. Transmitter linearity was improved substantially through the use of predistortion. The thermal noise contribution of the receiver was reduced by use of a new low‐noise microwave preamplifier.

The paper describes some of the key networks needed for the AR6A System for the predistorter, Intermediate Frequency (IF) filtering, and terminal multiplex. The design of a passive broadband adjustable phase splitter for the predistorter is described. Network designs using inductors, capacitors, and, in some cases, crystals for IF filtering, equalization, and multimastergroup connection are also described.

TH-3 Microwave Radio System: Networks

Abstract: This paper describes the filters and networks which provide the frequency selectivity required in the TH‐3 microwave transmitter and receiver, and the equalizers, which compensate amplitude and delay distortions introduced by the filters.
