This port is connected with PC port by controlling 2nd pin (VCTL (H)) to 2.5~6.5V and 4th pin (VCTL(L)) to -0.2~+0.2V. An external capacitor is required to block the DC bias voltage of internal circuit. (0.1~0.5GHz: 1000pF, 0.5~3GHz: 56pF, 3~5GHz: 27pF) 2 VCTL2 Control port 2. The voltage of this port controls PC to P2 state. The `ON' and `OFF' state is toggled by controlling voltage of this terminal such as high-state (2.5~6.5V) or low-state (-0.2~+0.2V). The voltage of 4th pin has to be set to opposite state. The bypass capacitor has to be chosen to reduce switching time delay from 10pF~1000pF range. 3 PC Common RF port. In order to block the DC bias voltage of internal circuit, an external capacitor is required. (0.1~0.5GHz: 1000pF, 0.5~3GHz: 56pF, 3~5GHz: 27pF) VCTL1 Control port 1. The voltage of this port controls PC to P1 state. The `ON' and `OFF' state is toggled by controlling voltage of this terminal such as high-state (2.5~6.5V) or low-state (-0.2~+0.2V). The voltage of 2nd pin has to be set to opposite state. The bypass capacitor has to be chosen to reduce switching time delay from 10pF~1000pF range. 5 P1 RF port. This port is connected with PC port by controlling 4th pin (VCTL(H)) to 2.5~6.5V and 2nd pin(VCTL(L)) to -0.2~+0.2V. An external capacitor is required to block the DC bias voltage of internal circuit(0.1~0.5GHz: 1000pF, 0.5~3GHz: 56pF, 3~5GHz: 27pF) 6 GND Ground terminal.
