An Economical Microwave Link System for 2700 Telephone Channels
Erik Myrseth · 1976
This system, carrying 2700 telephone channels per carrier in the 6 GHz band, meets all relevant CCIR recommendations. Key features include easy maintenance during operation, all solid state except for the very high efficiency TWT, 300 channels insert. Computer aided design of SHF and IF filters and circuits, optimized for flat delay response. AGC ahead of receiver preamplifier, low noise figure and high dynamic range AGC amplifier, lead to optimized performance during fading conditions. A novel amplitude limiter of simple construction.
