This port is connected to PC port by control voltage of +1.3~4.5V(VCTL(H)) at 5th pin. In order to block DC bias voltage of internal circuit, an external capacitor is required. 2 GND Ground terminal. Please connect this terminal with ground plane as close as possible for good RF performance. 3 P2 RF port. This port is connected to PC port by control voltage of +0.0~0.4V(VCTL(L)) at 5th pin. In order to block DC bias voltage of internal circuit, an external capacitor is required. 4 GND Ground terminal. Please connect this terminal with ground plane as close as possible for good RF performance. VCTL Control port. This terminal is set to +1.3V~4.5V of logical high level for ON state between PC and P1 RF ports, and set to +0.0~0.4V of logical low level for ON state between PC and P2 RF ports. 6 PC Common RF port. This PC port is connected to P1 or P2 by logical control voltage of VCTL. In order to block DC bias voltage of internal circuit, an external capacitor is required. 7 VDD A supply voltage terminal (+2.5~+4.5V). Please place a bypass capacitor between this and GND for avoiding RF noise from outside. 8 GND Ground terminal.
