Function

Description

Interface Schematic

1RF OUT1

RF output pin for ~900MHz LNA. This pin is an open-collector output. It

must be biased to either VCC or pin 4 through a choke or matching induc-

tor. It is typically matched to 50

Ω with a shunt bias/matching inductor and

series blocking/matching capacitor. Refer to application schematics.

2GND

Ground connection.

NOTE: Ground traces on pins 2 and 7 are equivalent to a small amount of

inductance (~0.75nH). The dimensions of these lines are as follows.

Pin 2: L=56mils, W=15mils, H=31mils

Pin 7: L=56mils, W=15mils, H=31mils

Dielectric is FR-4.

3RF OUT2

RF output pin for ~1900MHz LNA. This pin is an open-collector output. It

must be biased to either VCC or pin 4 through a choke or matching induc-

tor. It is typically matched to 50

Ω with a shunt bias/matching inductor and

series blocking/matching capacitor. Refer to application schematics.

4EN1

Enable pin for ~900MHz LNA. A voltage equal to the supply voltage LNA.

This pin should be disabled (0V) when the ~1900MHz LNA is in use.

5EN2

Enable pin for ~1900MHz LNA. A voltage equal to the supply voltage LNA.

This pin should be disabled (0V) when the ~900MHz LNA is in use. See

package drawing for description of pin orientation.

See pin 3.

6RF IN2

RF input pin for ~1900MHz. This pin is matched to approximately 50

Ω at

DCS/PCS frequencies. An external AC coupling capacitor is required at this

pin.

See pin 3.

7GND

Same as pin 2.

See pin 2.

8RF IN1

RF input pin for ~900MHz. This pin is matched to approximately 50

Ω at

GSM/Cellular frequencies. An external AC coupling capacitor is required at

this pin.

See pin 1.
