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 25°C (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.
