    micro DOUBLE SIX SWITCH operation principle

    A special method of power relays connection is employed, excluding to switch both radio ports into the same antenna. Additional signal relays ensure maximum separation even with faulty control drive. Without this protection feature the isolation between radio ports would decrease to half. As an example, at output power of 1000W = 60dBm, with faulty control drive the other radio port would experience 25dBm = 0.3W instead of -10dBm = 0.0001W, considering single relay isolation of 35dB.
