Table 1: Pin Description

PIN

NAME

DESCRIPTION

1

GND

Ground

2

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

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

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

5 GHz Supply Voltage. Bias for power transistors of the 5 GHz PA.

8

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

9

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.

10

GND

Ground

11

GND

Ground

12

2 GHz RF Output. 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 output stage. Route RF traces as coplanar waveguide using adjacent ground pins.

13

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

14

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

15

GND

Ground

16

2 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.
