LTC4400-1/LTC4400-2
sn4400 4400fas
RF (Pins 1/8):
RF Feedback Voltage. This input is referenced
to V
CC
. The frequency range is 300MHz to 2700MHz for the
LTC4400-1 and 300MHz to 2000MHz for the LTC4400-2.
This pin has an internal 250
termination, an internal
Schottky diode detector and peak detector capacitor.
GND (Pins 2/4):
System Ground.
PCTL (Pins 3/5):
Analog Input. The external power control
DAC drives this input. The amplifier servos the RF power
until the RF detected signal equals the DAC signal. The
input impedance is typically 90k
.
V
PCB
(Pin 3): (LTC4400-2 Only)
Power Control Voltage
Output. This pin drives an external RF power amplifier
power control pin. The maximum load capacitance is
100pF.
SHDN (Pins 4/6):
Shutdown Input. A logic low on the SHDN
pin places the part in shutdown mode. A logic high places
the part in enable mode. SHDN has an internal 150k pull-
down resistor to ensure that the part is in shutdown when
the drivers are in a three-state condition.
V
PCA
(Pins 5/2):
Power Control Voltage Output. This pin
drives an external RF power amplifier power control pin.
The maximum load capacitance is 100pF.
V
CC
(Pins 6/1):
Input Supply Voltage, 2.7V to 6V. V
CC
should be bypassed with 0.1
μ
F and 100pF ceramic capaci-
tors. Used as return for RF 250
termination.
BSEL (Pin 7): (LTC4400-2 Only)
Selects V
PCA
when Low
and V
PCB
when High. This input has an internal 150k
resistor to ground.
