Pin Description
PIN
NAME
FUNCTION
1, 9
V
CC
Power Supply. Bypass to GND with capacitors as close to the pin as possible as shown in the typical
application circuits (Figures 1 and 2).
2
RF_IN
Signal Input. Internally matched to 50
over the operating frequency. See the
typical application
circuit for recommended component values.
3, 18, 20, EP
GND
Ground. Use low-inductance layout techniques on the PC board. Solder the exposed paddle to the
board ground plane.
4
8
B4
B0
Attenuation Control Bits. Digital input for attenuation control. See Table 3 for attenuation setting.
10
RF_OUT-
Inverted Differential Signal Output. Requires an external pullup choke inductor (120mA typical
current) to V
CC
along with a DC-blocking capacitor; see Figures 1 and 2.
11
RF_OUT+
Noninverted Differential Signal Output. Requires an external pullup choke inductor (120mA typical
current) to V
CC
along with a DC-blocking capacitor; see Figures 1 and 2.
12
I
BIAS
Amplifier Bias Input. See Figures 1 and 2 for detailed connection.
13
C
BP
Bypass Capacitor. See Figures 1 and 2 for detailed connection.
14
L
E
Amplifier DC Ground. Requires choke inductor that can handle supply current. DC resistance of
inductor should be less than 0.2
.
15
AMP
IN
Amplifier Input. Requires DC-coupling to allow biasing.
16
C
C
Compensation Capacitor. Requires connection to AMP
IN
(pin 15) for stability.
17
I
SET
Connect R1 from I
SET
to GND (see Table 1 or Table 2 for values).
19
ATTN
OUT
Attenuator Output. Requires external DC-blocking capacitor.
