HQR445C

4:1 redundant L-Band Line Amplifier, 1+1 to 4+1 (variable gain 0 to 40dB)

The HQR445C is a compact and flexible 4+1 redundant L-Band line amplifier system built into a 1RU/19” rack mount chassis. The variable gain adjustment ranges from 0 to 40dB (1dB steps) while it also supports slope equalization so to achieve best performance within the RF distribution chain. The HQR445C chassis holds up to five high dynamic HQA45MI amplifier modules (950 – 2150MHz or 850 – 2700MHz) thus allowing an amplifier redundancy operation from 1+1 to max. 4+1 (field expandable, hot-swappable).
