TERMINAL INFORMATION No. SYMBOL 1 P1 2 GND 3 P2 4 VCTL2 5 PC 6 VCTL1 DESCRIPTION RF port. This port is connected with PC port by controlling 4th pin (VCTL(H)) to 2.5~6.5V and 6th pin(VCTL(L)) to -0.2~+0.2V. An external capacitor is required to block the DC bias voltage of internal circuit Ground terminal. Please connect this terminal with ground plane as close as possible for excellent RF performance. RF port. This port is connected with PC port by controlling 6th 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. Control port 2. 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 6th pin have to be set to opposite state. The bypass capacitor has to be chosen to reduce switching time delay from 10pF~1000pF range. Common RF port. In order to block the DC bias voltage of internal circuit, an external capacitor is required. Control port 1. 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 have to be set to opposite state.
