C3 / L1 tunes the input return loss 2. L2 / C4 tunes the output return loss with some contribution from C6. 3. R1 / L3 sets the level of feedback while B2 provides the bias path with RF isolation from the RF output path. 4. R2 helps control high end tilt/peaking. 5. 1 M Ω Resistor can be added from the input to VDD to increase linearity, trading off degraded noise figure and return loss.

Ground/thermal vias are critical for the proper performance of this device. Vias should use a .35 mm (#80 /.0135’) diameter drill and have a final, plated thru diameter of 0.25 mm (0.010”). 2. Add as much copper as possible to inner and outer layers near the part to ensure optimal thermal performance. 3. RF trace width depends upon the PC board material and construction. 4. All dimensions are in millimeters (inches). Angles are in degrees. Package Marking Recommended Mounting Pattern
