Function and Applications

RF input pin.

This pin should be coupled with

capacitor (example 100 pF) for DC

cut. Input return loss can be

improved with external impedance

matching circuit.

Ground pin.

This pin should be connected to

system ground with minimum

inductance. Ground pa- ttern on

the board should be formed as

wide as possible. Ground pins

must be connected together with

wide ground pattern to decrease

impedance difference.

RF output pin.

This pin is de-signed as open

collector of high impedance. This

pin must be externally equipped

with matching circuits.

−

Supply voltage pin.

This pin must be equipped with

bypass capacitor (example 1 000

pF) to minimize its RF impedance.

−

Gain control pin.

Note Pin voltage is measured at VCC = 3.0 V
