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 50 at 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.
