Description
Interface Schematic
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.
This pin requires a regulated supply to set output stage DC bias.
RF Input. An external blocking capacitor is required if this pin is con-
VCC
nected to DC path.

No Connect.
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.
VREG1
VCC BIAS
PWR SENSE
This pin requires a regulated supply to set driver stage DC bias.
Bias circuitry supply voltage.
PWR SEN and PWR REF pins can be used in conjunction with an exter-
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.

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.
