Function
RF IN
Description
RF input. Matching network with DC block required, see evaluation
board schematic for details.
Interface Schematic

BIAS GND1
PWR SEN
Ground for first stage bias circuit. Not connected.
See pin 5.
The PWR SEN and PWR REF pins can be used in conjunction with an
external feedback path to provide an RF power control function for the
RF5117. The power control function is based on sampling the RF drive
to the final stage of the RF5117.

VREG1
Same as pin 3.
See pin 3.
This pin requires a regulated supply to maintain nominal bias current.

VREG2
BIAS GND2
Same as pin 5.
See pin 5.
Ground for second stage bias circuit. For best performance connect to
ground with a 10nH inductor.
Not connected.
See pin 5.

Not connected.
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 a quarter-wave length microstrip line that is RF grounded at the
other end, or through an RF inductor that supports the required DC cur-
rents.
Same as pin 10.

Interstage match and bias for first stage output. Connect interstage
matching capacitor to this pad with a short trace. Connect low-fre-
quency bypass capacitors to this pin with a long trace. See evaluation
board layout for details.

Ground connection. The backside of the package should be connected
to the ground plane through a short path, i.e., vias under the device will
be required.
