DETECTOR
7 Power detector output
GND
8 Grounding
GND
9 Grounding
MODE
10 Mode switch; floating = high gain, grounded = low gain
GND
11 Grounding
ANT
12 Output pin, RF, to antenna
RF_GND
13 RF ground must be connected
GND
14 Grounding
PWRUP
15 Power up pin. HIGH = amplifier is on. LOW = amplifier is off.
V_DD_BIAS
16 Analog supply, V_DD for biasing the amplifier, 5 mA
All GND pins should be connected to ground to guarantee the best performance.
