IF Frequency Converter Products; 

IF70 70MHz to 140MHz Up Converter 

IF140 140MHz to 70MHz Down Converter 

The IF series Converters are 19-inch 1U rack mounted, 140MHz/70MHz Up & DownConverters. These Converters provide a low-cost solution for matching the IF’s of modems, converters and other units. Incorporated are high stability Ovenised Crystal Oscillators to ensure excellent stability and phase noise. Full alarm monitoring ensures that these units are fully compatible with the RCU100 and RCU200 1:1 and 1:2 redundancy controller units. 

The IF series Converters are designed to meet the phase noise, spurious, level and frequency stability requirements of Intelsat IBS/Eutelsat SMS specifications and are compliant with IESS 308/309. The products are suitable for both very high and very low data rates and both digital and analogue TV signals. 

The versatility of the design of these units ensures that customers’ specific requirements, such as gain and center frequency, can be accommodated.
