Product Description  
The RF5515 is a high performance Low Noise Amplifier design for  
802.11a applications (4.9GHz to 5.85GHz) and other portable consumer  
electronics. This miniature LNA features a high dynamic range and high  
intercept point with low current consumption around 12mA. The LNA is  
DC blocked and internally matched to 50at input and output pins. The  
IC is featured in a 2.2mm x 2.2mm x 0.5mm module compatible plastic  
package.

Note:  
*If DC Voltage is at Pin 5 from the  
device after the LNA, then an external  
DC-blocking capacitor is needed due  
to the internal shunt inductor on Pin 5  
as shown in the schematic above.  
** On the evaluation board adding  
C1, which is 1 uF, did not make any  
difference but could be needed  
depending on the layout and the  
nature of the supply voltage used in  
the system.

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.

PCB Stencil Pattern  
Note: 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. Example of the number and size of vias can be found on the RFMD evaluation board layout.
