3.00
The RF3163 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 amplifier in 3V IS-95/CDMA 2000
1X/AMPS handheld digital cellular equipment, spreadspectrum systems, and other applications in the 824MHz
to 849MHz band. The RF3163 has a digital control line
for low power applications to lower quiescent current. The
RF3163 is assembled in a 16-pin, 3mmx3mm, QFN
package.

Description
Interface Schematic
No connection. Do not connect this pin to any external circuit.
Regulated voltage supply for amplifier bias circuit. In power down
mode, both VREG and VMODE need to be LOW (<0.5V).
For nominal operation (High Power mode), VMODE is set LOW. When
set HIGH, devices are biased lower to improve efficiency.
RF input internally matched to 50Ω. This input is internally AC-coupled.
First stage collector supply. A 2200pF and 4.7µF decoupling capacitor
are required.
No connection. Do not connect this pin to any external circuit.
No connection. Do not connect this pin to any external circuit.

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.

One example is Toko 0603 multilayer inductor with the
value of 1.8 nH (Toko part number LL1608-F1N8S).
The value of the inductor can be from 1.5nH to 2.2nH.
Different values of the inductor will give slight shift on
the tradeoff between efficiency and ACPR.

PCB Design Requirements
PCB Surface Finish
The PCB surface finish used for RFMD’s qualification process is electroless nickel, immersion gold. Typical thickness is
3µinch to 8µinch gold over 180µinch nickel.
PCB Land Pattern Recommendation
PCB land patterns are based on IPC-SM-782 standards when possible. The pad pattern shown has been developed and
tested for optimized assembly at RFMD; however, it may require some modifications to address company specific
assembly processes. The PCB land pattern has been developed to accommodate lead and package tolerances.
PCB Metal Land Pattern

PCB Solder Mask Pattern
Liquid Photo-Imageable (LPI) solder mask is recommended. The solder mask footprint will match what is shown for the
PCB metal land pattern with a 2mil to 3mil expansion to accommodate solder mask registration clearance around all
pads. The center-grounding pad shall also have a solder mask clearance. Expansion of the pads to create solder mask
clearance can be provided in the master data or requested from the PCB fabrication supplier.

Thermal Pad and Via Design
The PCB land pattern has been designed with a thermal pad that matches the die paddle size on the bottom of the
device.
Thermal vias are required in the PCB layout to effectively conduct heat away from the package. The via pattern has been
designed to address thermal, power dissipation and electrical requirements of the device as well as accommodating
routing strategies.
The via pattern used for the RFMD qualification is based on thru-hole vias with 0.203mm to 0.330mm finished hole size
on a 0.5mm to 1.2mm grid pattern with 0.025mm plating on via walls. If micro vias are used in a design, it is suggested
that the quantity of vias be increased by a 4:1 ratio to achieve similar results.
