Product Description
The RF3164 is a high-power, high-efficiency linear amplifier module specifically
designed for 3V handheld systems. The device is manufactured on an advanced
third generation GaAs HBT process, and was designed for use as the final RF ampli-
fier in 3V IS-95/CDMA 2000 1X handheld digital cellular equipment, spread-spec-
trum systems, and other applications in the 1850MHz to 1910MHz band. The
RF3164 has a digital control line for low power applications to lower quiescent cur-
rent. The RF3164 is assembled in at 16-pin, 3mmx3mm, QFN package.

Description
RF input internally matched to 50Ω. This input is internally AC-coupled.
Ground connection.
For nominal operation (High Power mode), V
MODE
is set LOW. When set
HIGH, devices are biased lower to improve efficiency.
Regulated voltage supply for amplifier bias circuit. In power down mode,
both V
REG
and V
MODE
need to be LOW (<0.5V).
No connection. Do not connect this pin to any external circuit.
No connection. Do not connect this pin to any external circuit.

No connection. Do not connect this pin to any external circuit.
RF output. Internally AC-coupled.
Output stage collector supply. Please see the schematic for required exter-
nal components.
Same as pin 10.
Same as pin 10.
No connection. Do not connect this pin to any external circuit.
Interstage matching. Connect to pin 15.
Interstage matching. Connect to pin 14.
First stage collector supply. A 4.7μF decoupling capacitor is required.
Ground connection. The backside of the package should be soldered to a
top side ground pad which is connected to the ground plane with multiple
vias. The pad should have a short thermal path to the ground plane.
