Description

1

VCC1

1.8 V Power Supply. It is recommended to place the decoupling capacitors as close to this pin as possible.

2

GND

Ground.

3

INPT

RF Input. This pin is a 50 Ω single-ended input.

4

RBIAS

Resistor Bias. For typical operation, connect a 442 Ω resistor from RBIAS to GND. It is recommended to

place the RBIAS resistor as close to the pin as possible.

5

BAND

Band Select Control. Select a logic low of 0 V for the lower frequency range from 5.9 GHz to 7.2 GHz.

Select a logic high of 1.8 V for the higher frequency range from 7.1 GHz to 8.5 GHz.

6, 7

OUTP, OUTN

RF Outputs. These pins are 100 Ω differential outputs.

8

VCC2

3.3 V Power Supply. It is recommended to place the decoupling capacitors as close to this pin as possible.

EPAD (EP)

Exposed Pad. The exposed pad must be soldered to a low impedance ground plane.
