product description

The SP 400 S is a selective receive preamplifier with transmit / receive switching. It offers a low noise figure and good large-signal behavior. In the case of low transmission powers, the transmit / receive switchover can be implemented using a built-in HF VOX circuit. This amplifier is built with a GaAs MMIC of the latest technology on a high quality microwave substrate in SMD technology. The band pass at the output of the amplifier ensures a good band selection so that all signals that are outside the useful band are effectively suppressed and do not overload the receiver used. This amplifier has a splash-proof, UV-resistant plastic housing and galvanized mast clamps with stainless steel screws for attachment to the antenna mast.
