Product Description
HyperLAN
The RF5355 is a linear, medium-power, high-efficiency power amplifier IC
designed specifically for battery-powered WiFi applications such as PC
cmini PCI, and compact flash applications. It is also designed to
mt IEEE802.11a, IEEE802.11n, IEEE802.16e (4.9GHz to 5.850GHz
only) WiMax, FCC, and ETSI requirements for operation in the 4.9GHz to
850GHz band. The device is manufactured on an advanced InGap GaAs
eterojunction Bipolar Transistor process, and has been designed for use
as the final RF amplifier in 5GHz WiFi and other spread-spectrum trans-
mitters. The device is provided in a QFN, 8-pin, 2.2mmx2.2mmx0.45mm,
leadless chip carrier with backside ground. The RF5355 operates from a
single supply and will be easily incorporated into WiFi and other designs
with minimal external components.

Power detector voltage is proportional to RF output power. May need exter-

bring output voltage to desired level.
PDETECT
RF output is internally matched to 50 and DC-blocking capacitor of about
1.8pF to 5.6pF depending on the layout is required externally if a switch is
used immediately after the PA that has DC voltage at the switch input
which is the same node at the RF output of the PA.

PCB Design Requirements
PCB Surface Finish
The PCB surface finish used for RFMD's qualification process is electroless nickel, immersion gold. Typical thickness is 3 micro-
inch to 8 micro-inch gold over 180 micro-inch nickel.
PCB Land Pattern Recommendation *
PCB land patterns for RFMD components are based on IPC-7351 standards and RFMD empirical data. The pad pattern shown
has been developed and tested for optimized assembly at RFMD. The PCB land pattern has been developed to accommodate
lead and package tolerances. Since surface mount processes vary from company to company, careful process development is
recommended.

Theory of Operation
The RF5355 is a three-stage device with a minimum gain of 28dB in the 4.9GHz to 5.850GHz ISM band. The RF5355 is
designed primarily for IEEE802.11a, IEEE802.11n, and IEEE802.16e in the 4.9GHz to 5.850GHz band where the available
supply voltage and current are limited. This amplifier will operate to (and below) the lowest expected voltage made available by
a typical PCMCIA slot in a laptop PC, and will maintain required linearity at decreased supply voltages.
The RF5355 requires only a single positive supply of 3.3V nominal (or greater) to operate to full specifications. Power control is
provided through one bias pin, VREG. The three bias voltages for the three stages are connected together on the die and only
one bias control voltage is needed (VREG). There is no external matching required on the input and outpuof the part, thus
allowing a minimal bill of material (BOM) parts count in end applications. Both the input and the output of the device are DC-
blocked.
For best results, the PA circuit layout from the evaluation board should be copied as closely as possible, particularly the ground
layout and ground vias. Other configurations may also work, but the design process is much easier and quicker if the layout is
copied from the RF5355 evaluation board. Gerber files of our designs are available on request. The RF5355 is not a difficult
part to implement, but care in circuit layout and component selection is always advisable when designing circuits to operate at
5GHz.
The RF5355 has primarily been characterized with a voltage on VREG of 2.85Vever, the RF5355 will operate from a
wide range of control voltages. If you prefer to use a control voltage that is significaly different than 2.85VDC, contact RFMD
