Pin
Function
Description
Interface Schematic
1NC
This pin is internally not connected.
2GND
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.
3GND
Same as pin 2.
4RF 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.
5NC
This pin is internally not connected.
6GND
Same as pin 2.
7GND
Same as pin 2.
8NC
This pin is internally not connected.
9NC
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 75
Ω 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 on this pin.
14
GND
Same as pin 2.
15
GND
Same as pin 2.
