RF port. This port is connected with PC port by controlling 6th pin (V
to 2.5~6.5V and 4th pin(V

) 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)
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 4th pin(V
to 2.5 – 6.5V and 6th pin(V

) 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)
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 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.

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.
