NOTES

1. NC = NO CONNECT. THE PINS ARE NOT CONNECTED

INTERNALLY; HOWEVER, ALL DATA SHOWN HEREIN WAS

MEASURED WITH THESE PINS CONNECTED TO RF/DC

GROUND EXTERNALLY.

2. EXPOSED PAD. EXPOSED PAD MUST BE CONNECTED TO

RF/DC GROUND.

Description

1

Supply Voltage Pin.

2

control voltage range in Table 2.

3

RFC

RF Common Port. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required on this pin.

4, 6 to 8,

13 to 16

NC

Not Internally Connected. These pins are not internally connected; however, all data shown in this data sheet is

measured with the NC pins externally connected to RF/dc ground on the evaluation board.

5

EN

Enable Input Pin. See Figure 5 for the EN interface schematic. Refer to Table 6 and the recommended input

control voltage range in Table 2.

9

RF1

RF Port 1. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required on this pin.

10, 11

GND

Ground. The package bottom has an exposed metal pad that must connect to the printed circuit board (PCB)

RF ground. See Figure 4 for the GND interface schematic.

12

RF2

RF Port 2. This pin is dc-coupled and matched to 50 Ω. A dc blocking capacitor is required on this pin.

EPAD

Exposed Pad. Exposed pad must be connected to RF/dc ground.
