Operating from a single 1.8V to 3.6V supply, the amplifier will easily be incorporated into WiFi designs with minimal external components. The device is provided in a 2.2mmx2.2mmx0.6mm, 8-pin, QFN with a backside ground. IG N The RF5373 is a two-stage device with a nominal gain of 28dB to 29dB in the 2.4GHz to 2.5GHz ISM band. The RF5373 is designed for multiple applications in the 2.4GHz to 2.5GHz band. The RF5373 requires only a single positive supply of 1.8V to 3.6V to operate to full specification. Power control is provided through one bias control input pin (VREG) which can range from 1.6V nominal and 1.85V maximum. 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 RF5373 evaluation board. Gerber files of our designs are available on request. D ES There are multiple applications where the RF5373 may be implemented, including IEEE802.11b/g and Bluetooth. Please review the RF5373 schematics for the optimum layout for a specific band. In order to obtain the best performance for an 802.11g application where the PA will be pulsed at <99% duty cycle, R1 must be populated with a 56 resistor. For all other applications where pulsing is not needed, R1 can be substituted with a 0 or a trace line. An application schematic for 2.5GHz operation is included that has two additional components, one shunt inductor, and one shunt capacitor, on the output for improved second harmonic rejection. This layout provides ~20dB rejection at 5GHz with a minimal BOM count. N EW The RF5373 is not a difficult part to implement, but care in circuit layout and component selection is always advisable when designing circuits to operate at 2.5GHz. The RF5373 evaluation board layout and schematic is also available using 0201 components which will help shrink the six of the total area of the power amplifier and matching components on the intended design.

Typical thickness is 3inch to 8inch gold over 180inch nickel. IG N 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. D ES 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. N O T FO R N EW PCB Metal Land and Solder Mask Pattern Thermal vias for center slug “C” should be incorporated into the PCB design. The number and size of thermal vias will depend on the application, the power dissipation, and the electrical requirements. Example of the number and size of vias can be found on the RFMD evaluation board layout. 12 of 13 7628 Thorndike Road, Greensboro, NC 27409-9421 · For sales or technical support, contact RFMD at (+1) 336-678-5570 or [email protected].
