Pin Function Description
Interface Schematic
1
NC
This pin is internally not connected.
2
GND
Ground connection. Keep traces physically short and connect immedi-
ately 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 applications. DC coupling of the input is not allowed, because this
will override the internal feedback loop and cause temperature instabil-
ity.
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 block-
ing 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.
RF IN
In lower power applications the value of RC can be increased to lower
the current and VD 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.
