NOTES

1. NC = NO CONNECT. THESE PINS ARE NOT CONNECTED INTERNALLY.

ALL DATA SHOWN WITHIN WAS MEASURED WITH THESE PINS

CONNECTED TO RF AND DC

GROUND EXTERNALLY.

2. THE EXPOSED PAD IS INTERNALLY CONNECTED TO GROUND.

SOLDER THE EXPOSED PAD TO A LOW IMPEDANCE GROUND PLANE.

Description

1 to 3, 7 to 10, 14, 17, 20 to 24, 28 to 40

NC

No Connect. These pins are not connected internally. All data shown within was

measured with these pins connected to RF and dc ground externally.

4, 6, 12, 16, 18, 25, 27

GND

Ground. These pins must be connected to RF and dc ground.

5

RFIN

RF Input. This pin is dc-coupled and matched to 50 Ω. Blocking capacitors are

required if the RF line potential is not equal to 0 V.

11

VEE

Negative Supply Voltage. VEE is −5 V.

13

VDD

Positive Supply Voltage. VDD is 5 V.

15

VCTL

Control Voltage for Band Selection. The device is in the high band when the

voltage is 0 V and in the low band when the voltage is 2.5 V.

19

VTUNE

Center Frequency Control Voltage of the Band-Pass Filter. VTUNE can be varied

from 0 V to 15 V.

26

RFOUT

RF Output. This pin is dc-coupled and matched to 50 Ω. Blocking capacitors are

required if the RF line potential is not equal to 0 V.

EPAD

Exposed Pad. The exposed pad is internally connected to ground. Solder the

exposed pad to a low impedance ground plane.
