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 an RX or TX port, while the other ports have high attenuation. 0.007 (0.180 mm) 0.030 (0.75 mm) ± 0.002 (0.05 mm) 0.017 (0.435 mm) Sq.
