Pin Function Description
Interface Schematic
1
GND
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
2
GND
Same as pin 1.
3
RF IN
DC coupled RF input. A broadband impedance match is produced by
internal shunt resistive feedback. The DC level is approximately
200mV. If a DC path exists in the connected circuitry, an external DC-
blocking capacitor is required to properly maintain the DC operating
point.
4
GND
Same as pin 1.
5
GND
Same as pin 1.
6
RF OUT RF output. A broadband impedance match is produced by internal
shunt resistive feedback. The DC connection to the power supply is
provided through an external chip inductor having greater than 150Ω
VDD
RF OUT
4
reactance at the operating frequency. An external DC-blocking capaci-
tor is required if the following circuitry is not DC-blocked.
RF IN
7
VDD2
Bias control connection. This pin is normally connected to the power
supply, but can be used to switch the amplifier on and off by switching
between power supply voltage and ground. This pin sinks approxi-
mately 600µA when connected to VDD, and sources less than 10µA
when grounded.
8
NC
No connection.
