Note

Function and applications

Internal equivalent circuit

INPUT

0.87

0.82

Signal input pin. A internal matching circuit,

configured with resistors, enables 50

connection over a wide band. this pin must be

coupled to signal source with capacitor for DC

cut.

OUTPUT

1.95

2.54

Signal output pin. A internal matching circuit,

configured with resistors, enables 50

connection over a wide band. This pin must

be coupled to next stage with capacitor for DC

cut.

6VCC

2.7 to 3.3

Power supply pin. This pin should be

externally equipped with bypass capacity to

minimize ground impedance.

GND

Ground pin. This pin should be connected to

system ground with minimum inductance.

Ground pattern on the board should be formed

as wide as possible. All the ground pins must

be connected together with wide ground

pattern to decrease impedance difference.

Note Pin voltage is measured at VCC = 3.0 V. Above:

mPC2745TB, Below: mPC2746TB
