LNB-Switch

The RT457B 4x2 switch matrix with tone/voltage decoder is designed for use in LNB (low noise block) at satellite outdoor system or similar DBS (Direct Broadcast Satellite) system. The four-input to two-output switch matrix is controlled by integrated tone/voltage decoder which follows 13V/18V dc vol • Frequency range: 0.1GHz to 2.15GHz\r\n\r\n• DiSEqC rejection tone detector\r\n\r\n• High isolation: minimum 32dB @ 2.15GHz\r\n\r\n• Four RF inputs, two RF outputs\r\n\r\n• Low current consumption: 1.5mA @ 3.3V\r\n\r\n• Low insertion loss: 7.5dB @ 2.15GHz\r\n\r\n• Shunt down function when voltage <;
