Switching between the antenna and TX/RX ports is accomplished with 3 control inputs. When the control inputs are driven with the appropriate voltages, a low insertion loss path is provided from an antenna port to a TX port, while the other RX ports have high attenuation. 0.022 (0.55 mm) 0.004 (0.10 mm) Electrical Specifications at 25C (0, +3 V) Parameter1 Insertion Loss2 Condition Ant-RX Frequency 0.1-1.0 GHz 1.0-2.0 GHz 2.0-2.5 GHz 0.1-1.0 GHz 1.0-2.0 GHz 2.0-2.5 GHz 0.1-1.0 GHz 1.0-2.0 GHz 2.0-2.5 GHz 0.1-1.0 GHz 1.0-2.0 GHz 2.0-2.5 GHz 0.1-2.5 GHz 0.20 0.40 0.55 24 20 20 20 14 10 Min.
