Table 1: Pin Description

PIN NAME DESCRIPTION

1

GND Ground

2 GHz RF Input. ESD structures on this pin provide a DC path to ground. Avoid

2 RFIN 2G 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.

5 GHz RF Input. AC coupled input stage internally matched to 50 . Route as coplanar

RFIN 5G

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 GHz Power Control. Power amplifier power control pin. The recommended use is for

5

PAON 5G

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.

5 GHz RF Output. AC coupled output stage internally matched to 50 . Route as

RFOUT 5G

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.

GND Ground

11

GND Ground

2 GHz RF Output. ESD structures on this pin provide a DC path to ground. Avoid

12 RFOUT 2G applying DC voltage to this pin. RF is internally matched to 50  and AC coupled to

the output stage. Route RF traces as coplanar waveguide using adjacent ground pins.

DETOUT 2G

2 GHz Power Detector Output. DC coupled power detector output. An emitter follower

BJT supplies the output for this pin. Output impedance is 2 k.

14 VCC 2G 2 GHz Power Supply. Bias for power transistors of the 2 GHz PA.

15

GND Ground

2 GHz Power Control. Power amplifier power control pin. The recommended use is for

16

PAON 2G

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.
