QTERMINAL INFORMATION
No. SYMBOL EXPLANATION
1 VCTL2
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 (2.7~5.5V) or low-state (-0.2~+0.2V). The voltage of 4th pin have
to be set to opposite state. The bypass capacitor has to be chosen to
reduce switching speed delay from 10pF~1000pF range.
2 PC 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)
3, 6, 7 GND Ground terminal. Please connect this terminal with ground plane as close
as possible for excellent RF performance.
4 VCTL1
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 (2.7~5.5V) or low-state (-0.2~+0.2V). The voltage of 1st pin have
to be set to opposite state. The bypass capacitor has to be chosen to
reduce switching speed delay from 10pF~1000pF range.
5 P1
RF port. This port is connected with PC port by controlling 4th pin (VCTL (H))
to 2.7~9.0V and 1st pin (VCTL (L)) to -0.2~+0.2V. An external capacitor is
required to block the DC bias voltage of internal circuit. (50~100MHz:
0.01µF, 0.1~0.5GHz: 1000pF, 0.5~2.5GHz: 56pF)
8 P2
RF port. This port is connected with PC port by controlling 1st pin (VCTL (H))
to 2.7~9.0V and 4th pin (VCTL (L)) to -0.2~+0.2V. An external capacitor is
required to block the DC bias voltage of internal circuit. (50~100MHz:
0.01µF, 0.1~0.5GHz: 1000pF, 0.5~2.5GHz: 56pF)

QAPPLICATION CIRCUIT
QRECOMMENDED PCB DESIGN
PRECAUTIONS
[1]The DC blocking capacitors have to be placed at RF terminal of P1, P2 and PC.
[2]Bypass capacitors (C4, C5) should be placed close to terminals of VCTL1, VCTL2 to reduce
stripline influence of RF characteristics.
[3]For good isolation, the GND terminal (3rd, 6th, 7th pin) must be placed possibly close to ground
plane of substrate, and through holes for GND should be placed near by the pin connection.
[4] To avoid degradation of isolation or high power characteristics, please layout ground pattern
right under this IC.
