Function

Description

Device Schematic

1

Vcc

VCC is the supply voltage for the active bias network.

Bypassing in the appropriate location as shown on

application schematic is required for optimum RF

performance.

2

Vbias

Vbias is the bias control pin for the active bias network.

Device current is set by the current into this pin.

Recommended configuration is shown in the Application

Schematic. Bypassing in the appropriate location as

shown on application schematic is required for optimum

RF performance.

3

RF In

RF input pin. This pin requires the use of an external

DC blocking capacitor chosen for the frequency of

operation.

No connection

6

RF Out/Vcc RF output and bias pin. Bias should be supplied to this

pin through an external RF choke. Because DC biasing

is present on this pin, a DC blocking capacitor should

be used in most applications (see application

schematic). The supply side of the bias network should

be well bypassed. An output matching network is

necessary for optimum performance.

EPAD

Gnd

Exposed area on the bottom side of the package needs

to be soldered to the ground plane of the board for

thermal and RF performance. Several vias should be

located under the EPAD as shown in the recommended

land pattern (page 5).
