Q TERMINAL INFORMATION

No. SYMBOL DESCRIPTION

1 P1

RF port. 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.

5 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. Please connect this terminal with ground plane as

close as possible for good RF performance.

PRECAUTIONS

[1]The DC blocking capacitors have to be placed at RF terminal of P1, P2 and PC. Please

choose appropriate capacitance values to the application frequency.

[2]For avoiding the degradation of RF performance, please place bypass capacitor(C4) as

close as possible to each terminal.

[3]For good isolation, the GND terminal must be connected with the ground plane of

substrate, and through-holes for GND should be placed near by the IC.
