Description

Interface Schematic

1, 2, 3

VCC1

Inter-stage match and bias for first stage output. Connect inter-stage

matching capacitor to pin with a short trace. Connect low frequency

bypass capacitor to this pin with a long trace. See evaluation board lay-

out for detail.

5VREG2

This pin requires a regulated supply to set output stage DC bias.

6RF IN

RF Input. An external blocking capacitor is required if this pin is con-

nected to DC path.

NC

No Connect.

17, 18

RF OUT

RF Output and bias for the output stage. The power supply for the out-

put transistor needs to be supplied to this pin. This can be done

through an RF inductor that supports the required DC currents.

19

VREG1

This pin requires a regulated supply to set driver stage DC bias.

22

VCC BIAS

Bias circuitry supply voltage.

23

nal feedback path to provide an RF power control function for the

RF6886. The power control function is based on sampling the RF drive

to the final stage of the RF6886.

24

PWR REF

Same as pin 23.

Pkg

Base

GND

Ground connection. The backside of the package should be connected

to the ground plane through a short path, i.e., vias under the device are

required.
