Function

Description

1TX_IN

RF input for the 802.11b/g PA. Input is matched to 50

 and DC block is provided.

2VREG

decoupling purposes.

3RX OUT

Receive port for 802.11b/g band. Internally matched to 50

. DC block provided.

4LNA VDD

Voltage supply for the LNA.

5

LNA_EN

Control voltage for the LNA. When this pin is set to a LOW logic state, the bypass mode is enabled.

6C RX

Receive switch control pin. See switch truth table for proper level.

7

C_TX

Switch control voltage for the transmit branch. See logic control table for proper settings.

8BT

 and DC block is provided.

9C_BT

10

ANT

Port matched to 50

 and is DC blocked internally.

11

GND

Ground.

12

N/C

No connect.

13

N/C

No connect.

14

VCC

Supply voltage for the PA.

15

VCC

Supply voltage for the PA.

16

PDETECT

Power detector voltage for TX section. PDET voltage varies with output power. May need external decoupling

capacitor for noise bypassing. May need external circuitry to bring output voltage to desired level.
