product description

The SP 70 S is a selective receiving preamplifier with transmit / receive switching for the 70 cm amateur band. It offers optimal amplification, low noise figure and good large-signal behavior. With low transmit powers, the transmit / receive switchover can be implemented using a built-in 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. This amplifier has a, splash-proof, UV-resistant plastic housing and galvanized mast clamps with stainless steel screws for attachment to the antenna mast.
