nTERMINAL INFORMATION

No. SYMBOL DESCRIPTIONS

1P1

RF port. This port is connected with PC port by controlling 6

pin (V

CTL (H)

)

to 2.5~6.5V and 4

pin(V

CTL(L)

) to -0.2~+0.2V. An external capacitor is

required to block the DC bias voltage of internal circuit. (50~100MHz:

0.01uF, 0.1~0.5GHz: 1000pF, 0.5~2.5GHz: 56pF)

2GND Ground terminal. Please connect this terminal with ground plane as close

as possible for excellent RF performance.

3P2

RF port. This port is connected with PC port by controlling 4

pin(V

CTL(H)

)

to 2.5 – 6.5V and 6

pin(V

CTL(L)

) to -0.2~+0.2V. An external capacitor is

required to block the DC bias voltage of internal circuit. (50~100MHz:

0.01uF, 0.1~0.5GHz: 1000pF, 0.5~2.5GHz: 56pF)

4VCTL2

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 6

have to be set to opposite state. The bypass capacitor has to be chosen

to reduce switching time delay from 10pF~1000pF range.

5PC Common RF port. In order to block the DC bias voltage of internal circuit,

an external capacitor is required. (50~100MHz: 0.01uF, 0.1~0.5GHz:

1000pF, 0.5~2.5GHz: 56pF)

6VCTL1

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 4

have to be set to opposite state. The bypass capacitor has to be chosen

to reduce switching time delay from 10pF~1000pF range.

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]To reduce stripline influence on RF characteristics, please locate bypass

capacitors(C4, C5) close to each terminals.

[3]For good isolation, the GND terminal (2nd pin) must be placed possibly close to ground

plane of substrate, and through holes for GND should be placed near by the pin

connection.
