Application Notes
1. Performance in a specifi ed frequency band can be optimized by changing component values in the demo board
2. Pin1 (Vbias pin) voltage in LNA mode can be varied to enable the LNA bias current to be adjusted, refer to next

RF Input
above to suit the application at that frequency. The schematic on page 5 and 11 show two sets of components used
to demonstrate performance at the (2.3 – 2.4) GHz Wibro band and (2.5 – 2.7) GHz WiMAX/DMB band.
