Satellite-IF Amplifiers

In satellite reception systems, most satellite receivers are designed to operate with an input signal level between -60dBm and -30dBm per channel. It is recommended that the signal level of satellite-IF distribution systems is not less than -50dBm per channel at the customer outlet.

In some conditions this means a line amplifier must be used to boost the signal (see below).

1. Long (more than 100 feet) runs of coaxial cable from LNB to satellite receiver.

2. In a satellite-IF distribution system where the signal level may become marginal
    toward the end of the system.

3. Prior to splitting a signal many ways which might cause excessive splitting loss.

The SA-23 series are all new designed line amplifiers. They offer high performance, high RFI shielding, better impedance match and flat sloping gain between 950 and 2300MHz to obtain cable slope compensation. They are suitable for use in general analog satellite system and especially digital system like DiSEqC and DSS satellite systems.

> More amplifiers, Zinc Alloy Die-cast Housing SA2 line amplifier series.


To boost the signal level of satellite-IF for long distances between dish and satellite receiver.
