nTERMINAL INFORMATION

No.

SYMBOL

EXPLANATION

RF port. This terminal is connected under the condition of

1

P1

2pin-VCTL(H) (+2.5~+6.5V), 4, 7, 9pin-VCTL(L) (-0.2~+0.2V).

A DC cut capacitor 56pF is reguired at this terminal to block DC

voltage of inner circuit.

2

VCTL1

Control port1. Please connect bypass capacitor (10pF) between this

terminal and GND close to this IC.

3

GND

Ground terminal. Please connect this terminal with ground plane as

close as possible for excellent RF performance.

4

VCTL2

Control port2. Please connect bypass capacitor (10pF) between this

terminal and GND close to this IC.

RF port. This terminal is connected under the condition of

5

P2

4pin-VCTL(H) (+2.5~+6.5V), 2, 7, 9pin-VCTL(L) (-0.2~+0.2V).

A DC cut capacitor 56pF is reguired at this terminal to block DC

voltage of inner circuit.

RF port. This terminal is connected under the condition of

6

P3

7pin-VCTL(H) (+2.5~+6.5V), 2, 4, 9pin-VCTL(L) (-0.2~+0.2V).

A DC cut capacitor 56pF is reguired at this terminal to block DC

voltage of inner circuit.

7

VCTL3

Control port3. Please connect bypass capacitor (10pF) between this

terminal and GND close to this IC.

Common RF port. This terminal is connected by the control voltage

supplied to each control terminal (VCTL1~VCTL4 terminal). Please

see the description of each terminal. A DC cut capacitor (56pF) is

PC

reguired at this terminal to block DC voltage of inner circuit.

This terminal and GND are connected by high resistance (200KΩ) to

avoid unexpected signal output that is possibly generated right after

burst signal switching.

9

VCTL4

Control port4. Please connect bypass capacitor (10pF) between this

terminal and GND close to this IC.

RF port. This terminal is connected under the condition of

10

P4

9pin-VCTL(H) (+2.5~+6.5V), 2, 4, 7pin-VCTL(L) (-0.2~+0.2V).

A DC cut capacitor 56pF is reguired at this terminal to block DC

voltage of inner circuit.
