PIN
NAME
DESCRIPTION
1
GND
Ground
2
RFIN 2G
2 GHz RF Input. ESD structures on this pin provide a DC path to ground. Avoid
applying DC voltage to this pin. RF is internally matched to 50 and AC coupled to
the input stage. Route RF traces as coplanar waveguide using adjacent ground pins.
3
RFIN 5G
5 GHz RF Input. AC coupled input stage internally matched to 50 . Route as coplanar
waveguide using adjacent ground pins. Although the input stage is AC coupled, a
shunt inductive matching element included inside the PA provides a DC path to ground
at this pin.
4
GND
Ground
5
PAON 5G
5 GHz Power Control. Power amplifier power control pin. The recommended use is for
on/off control of the PA. Nominally, 0 V applied will turn amplifier completely off; a
voltage of 2.0 V and above will set the PA to maximum output capability. Current draw
on this pin is approximately 0.5 mA at +3.3 V.
6
GND
Ground
7
VCC 5G
5 GHz Supply Voltage. Bias for power transistors of the 5 GHz PA.
8
DETOUT 5G 5 GHz Power Detector Output. DC coupled power detector output. An emitter follower
BJT supplies the output for this pin. Output impedance is 2 k.
9
RFOUT 5G
5 GHz RF Output. AC coupled output stage internally matched to 50 . Route as
coplanar waveguide using adjacent ground pins. Although the output stage is AC
coupled, a shunt inductive matching element included inside the PA provides a DC
path to ground at this pin.
