RF5163
Pin Function Description
Interface Schematic
1
RF IN
RF input. Matching network with DC-block required; see evaluation
See pin 14.
board schematic for details.
2
VREG1 ^{First stage bias circuit ground. Keep PCB traces short and connect}
GND
immediately to ground plane.
3
P DOWN ^{Power down pin. Apply <0.6V}DC ^{to power up both V}CC ^{and V}CC1^{. Apply}
2.5V_DC to 3.5V_DC to power down. If function is not desired pin may be
grounded.
4
P 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.
5
VREG1 ^{First stage bias input - requires regulated voltage to maintain desired}
I_CC.
6
VREG2 ^{Second stage bias input - requires regulated voltage to maintain}
desired I_CC. May be tied to pin 5 input after series resistors.
7
VREG2 ^{Second stage bias circuit ground. Ground with a 10nH inductor.}
GND
8
NC
No connect (N/C).
9
GND
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.
RF OUT
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.
VCC
RF IN
15
16
Pkg
Base
VCC1
VCC
GND
BIAS
Same as pin 14.
Power supply pin for bias circuits. External low frequency bypass
capacitors should be connected if no other low frequency decoupling is
employed.
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.
