Pin
Function
Description
Interface Schematic
1RF IN
RF input. Matching network with DC-block required; see evaluation
board schematic for details.
See pin 14.
2VREG1
GND
First stage bias circuit ground. Keep PCB traces short and connect
immediately to ground plane.
3P DOWN
Power down pin. Apply <0.6VDC to power up both VCC and VCC1. Apply
2.5VDC to 3.5VDC to power down. If function is not desired pin may be
grounded.
4P DETECT
The P_DOWN and P_DETECT pins can be used in conjunction with an
external feedback path to provide an RF power control function for the
RF5163. The power control function is based on sampling the RF drive
to the final stage of the RF5163. If function is not desired, pin may be
left unterminated.
5VREG1
First stage bias input - requires regulated voltage to maintain desired
ICC.
6VREG2
Second stage bias input - requires regulated voltage to maintain
desired ICC. May be tied to pin 5 input after series resistors.
7VREG2
GND
Second stage bias circuit ground. Ground with a 10nH inductor.
8NC
No connect (N/C).
9GND
Ground connection. For best performance, keep PCB trace lengths
short.
10
RF OUT
Same as pin 11.
11
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 (
λ/4) microstrip line that is RF grounded at the
other end, or through an RF inductor that supports the required DC cur-
rent.
12
RF OUT
Same as pin 11.
13
GND
Same as pin 8.
14
VCC1
Power supply pin for first stage. External low frequency bypass capaci-
tors should be connected if no other low frequency decoupling is
employed.
15
VCC1
Same as pin 14.
16
VCC
Power supply pin for bias circuits. External low frequency bypass
capacitors should be connected if no other low frequency decoupling is
employed.
Pkg
Base
GND
Ground connection. The back side of the package should be connected
to the ground plane through as short a connection as possible, e.g.,
PCB vias under the device are recommended.
See pins 1 and 2.
