Pin Function Description
Interface Schematic
1
NC
This pin is internally not connected.
2
GND
Ground connection. Keep traces physically short and connect immediately
to ground plane for best performance. Each ground pin should have a via
to the ground plane.
3
GND
Same as pin 2.
4
RF IN
RF input pin. This pin is NOT internally DC blocked. A DC blocking capacitor,
suitable for the frequency of operation, should be used in most applica-
tions. DC coupling of the input is not allowed, because this will override the
internal feedback loop and cause temperature instability.
5
NC
This pin is internally not connected.
6
GND
Same as pin 2.
7
GND
Same as pin 2.
8
NC
This pin is internally not connected.
9
NC
This pin is internally not connected.
10
GND
Same as pin 2.
11
GND
Same as pin 2.
12
NC
This pin is internally not connected.
13
RF OUT
RF output and bias pin. Because DC is present on this pin, a DC blocking
capacitor, suitable for the frequency of operation, should be used in most
applications. For biasing, an RF choke in series with a resistor is needed.
The DC voltage on this pin is typically 8.3V with a current of 150mA (for
75Ω board). See device voltage versus device current plot. In lower power
applications the value of RC can be increased to lower the current and VD RF IN
on this pin.
RF OUT
14
GND
Same as pin 2.
15
GND
Same as pin 2.
16
NC
This pin is internally not connected.
