Pin Function Description
Interface Schematic
1
RF 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 50Ω with a shunt bias/matching inductor and
RF IN1
RF OUT1
series blocking/matching capacitor. Refer to application schematics.

Ground connection.
NOTE: Ground traces on pins 2 and 7 are equivalent to a small amount of
LNA1
LNA2
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
Pin 2
Dielectric is FR-4.
Pin 7
3
RF 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 50Ω with a shunt bias/matching inductor and
series blocking/matching capacitor. Refer to application schematics.
RF IN2
RF OUT2
4
EN1
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.
5
EN2
Enable pin for ~1900MHz LNA. A voltage equal to the supply voltage LNA. See pin 3.
This pin should be disabled (0V) when the ~900MHz LNA is in use. See
package drawing for description of pin orientation.
6
RF IN2
RF input pin for ~1900MHz. This pin is matched to approximately 50Ω at See pin 3.
DCS/PCS frequencies. An external AC coupling capacitor is required at this
pin.
7
GND
Same as pin 2.
See pin 2.
8
RF IN1
RF input pin for ~900MHz. This pin is matched to approximately 50Ω at See pin 1.
GSM/Cellular frequencies. An external AC coupling capacitor is required at
this pin.
