Pin

Function

Description

1RFN

Differential RF input for PA (TX_Mode) and output for LNA (RX_Mode) internally matched to 100

Ω.

2GND

Ground.

3RFP

Differential RF input for PA (TX_Mode) and output for LNA (RX_Mode) internally matched to 100

Ω.

4VCC

Voltage supply for VCC Bias. An external 0.1uF capacitor might be needed for low frequency decoupling.

5TX_EN

Enable voltage pin for the PA and switch. See logic table for operation.

6PDET

Provides and output voltage proprtional to the output RF level.

7GND

Ground.

8

VCC1/2

Voltage supply for the first and second stages of the PA. An external 1uF capacitor might be needed for low fre-

quency decoupling.

9C/I

This pin is connected internally (C/I) to Pin 8 therfore this pin should not be grounded. This pin should be left

open.

10

VCC3

Voltage supply for the third stage of the PA. An external 1uF capacitor might be needed for low frequency decou-

pling

11

NC

No connect.

12

GND

Ground.

13

ANT1

This is a common port (antenna). It is matched to 50

Ω and DC block is provided internally.

14

GND

Ground.

15

ANT2

This is a common port (antenna). It is matched to 50

Ω and DC block is provided internally.

16

ANT2_EN

Control pin for antenna select. See logic table for operation.

17

ANT1_EN

Control pin for antenna select. See logic table for operation.

18

VCCLNA

Voltage supply. An external 1uF capacitor might be needed for low frequency decoupling.

19

LNA_EN

LNA enable pin for selecting between High gain mode and Bypass mode.

20

RX_EN

Enable voltage pin for the Receive mode and switch. See logic table for operation.
