17, 21, 24, 26, 30, 31, 32

NC

No Connect. Do not connect to these pins. Leave these pins floating.

2, 3

RFIP

Positive RF Amplifier Input. RFIP and RFIN form a differential input.

6, 7

RFIN

Negative RF Amplifier Input. RFIP and RFIN form a differential input.

12

TIEA

Connect TIEA and TIEB (Pin 13) together externally.

13

TIEB

Connect TIEB and TIEA (Pin 12) together externally.

18, 19

RFON

Negative Amplifier RF Output. A choke inductor is required to provide dc current and RF isolation. A dc blocking capacitor is

also required. See Figure 31 for specific recommendations.

14, 16

FBN

Negative Feedback Path. Place an 0201 capacitor between Pin 14 and Pin 16. See Figure 31 for specific recommendations.

20

RSET

Bias Resistor. The voltage must be pulled up or down depending on target bias voltage (see Supply Voltage and Bias

Current ). See Figure 31 for specific recommendations.

22, 23

RFOP

Positive Amplifier RF Output. A choke inductor is required to provide dc current and RF isolation. A dc blocking capacitor is

also required. See Figure 31 for specific recommendations.

25, 27

FBP

Positive Feedback Path. Place an 0201 capacitor between Pin 25 and Pin 27. See Figure 31 for specific recommendations.

28

TIEC

Connect TIEC and TIED (Pin 29) together externally.

29

TIED

Connect TIED and TIEC (Pin 28) together externally.

EPAD

Exposed Pad. Solder the exposed paddle to a low impedance electrical and thermal ground plane.
