TERMINAL INFORMATION
No. SYMBOL EXPLANATION
1 VCTL2
Control port 2. The voltage of this port controls PC to P1 state. The ‘ON’ and
‘OFF’ state is toggled by controlling voltage of this terminal such as high-state
(2.5~5.5V) or low-state (-0.2~+0.2V). The voltage of 3rd pin has 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. (1~500MHz: 1uF, 0.5~2.5GHz: 56pF)
3 VCTL1
Control port 1. The voltage of this port controls PC to P1 state. The ‘ON’ and
‘OFF’ state is toggled by controlling voltage of this terminal such as high-state
(2.5~5.5V) or low-state (-0.2~+0.2V). The voltage of 1st pin has to be set to
opposite state. The bypass capacitor has to be chosen to reduce switching
speed delay from 10pF~1000pF range.
4 P1
RF port. This port is connected with PC port by controlling 1st pin (V
CTL (H)
) to
2.5~5.5V and 3rd pin (V
CTL (L)
) to -0.2~+0.2V. An external capacitor is required
to block the DC bias voltage of internal circuit. (1~500MHz: 1uF, 0.5~2.5GHz:
56pF)
5 GND Ground terminal. Please connect this terminal with ground plane as close as
possible for excellent RF performance.
6 P2
RF port. This port is connected with PC port by controlling 3rd pin (V
CTL (H)
) to
2.5~5.5V and 1st pin (V
CTL (L)
) to -0.2~+0.2V. An external capacitor is required
to block the DC bias voltage of internal circuit. (1~500MHz: 1uF, 0.5~2.5GHz:

APPLI CATION CIRCUIT: Sing le control signal operat ion by using C- MOS inverter
(frequency range: 0.1~2.0GHz)
RECOMM ENDED PCB DESIGN
PRECAUTIONS
[1] The external capacitors should be connected to the input and output RF terminals
(P
1
, P
2
, P
C
) to block DC current. Please use a 0.1uF capacitor at 1 to 500MHz, a
56pF at 500MHz to 2.0GHz.
[2] To avoid coupling between terminals, the capacitors have to be placed at the
control ter minals (V
CTR1
, V
CTR2
) as close as possible. The capacitor values of 1000pF
at 1 to 500MHz, 10pF at 500MHz to 2GHz are desired. In g eneral, t he switching tim e
is depending on the capacitor values, so please be careful choosing capacitor
values.
[3] For good isolation characteristics, the ground terminals (5pin) should be directly
connected to the ground patterns and through-holes as close as possible using
relatively wide patterns.
