Pin

Function

Description

1LNA BIAS

Voltage supply for the LNA. Without LNA Bias “on”, the LNA will be switched into Bypass Mode.

2RX OUT

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

. DC block provided.

3TX IN

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

 and DC block is provided.

4VREG

pling purposes.

5PDETECT

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

6VCC B

Supply voltage for the bias circuit of the PA. Add an external 56pF bypass capacitor for low frequency decoupling.

7

VCC 1

Supply voltage for the first stage of the PA. Add an external 1nF capacitor for low frequency decoupling.

8N/C

No connect.

9

VCC 2

Supply voltage for the second stage of the PA. Add an external 0.1uF capacitor for low frequency decoupling.

10

GND

Ground.

11

ANT

Antenna port. This pin is internally matched for a 50

 load and it is a DC short to ground. See functional block diagram

for more details.
