The RF6100-1 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 RF6100-1 has a digital control line
for low power applications to lower quiescent current. The
device is self-contained with 50Ω input and output that is
matched to obtain optimum power, efficiency and linearity. The module is a 4mmx4mm land grid array with backside ground. The RF6100-1 is footprint compatible with
industry standard 4mmx4mm CDMA modules, and
requires only one decoupling capacitor.

Description
Interface Schematic
Regulated voltage supply for amplifier bias. 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.
Ground connection. Connect to package base ground. For best performance, keep traces physically short and connect immediately to
ground plane.
RF input internally matched to 50Ω. This input is internally AC-coupled.
First stage collector supply. A low frequency decoupling capacitor
(e.g., 4.7µF) may be required.
Output stage collector supply. A low frequency decoupling capacitor
(e.g., 4.7µF) is required.

Ground connection. Connect to package base ground. For best performance, keep traces physically short and connect immediately to

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.

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.

Thermal Pad and Via Design
The PCB metal land pattern has been designed with a thermal pad that matches the exposed 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.
