*Application Notes: -
1. Performance in a specified frequency band can be
2. Operational Logic of Bypass/Shutdown pin (Pin 1)
Pin 1 voltage in LNA mode can be varied to enable
the LNA bias current to be adjusted, refer to next
graph:
optimized by changing component values in the
demoboard above to suit the application at that
frequency. The schematic on page 4 and 7 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.
- Normal LNA operation : [1.2 to (Vdd-0.3)] Volt,
- Bypass/Shutdown mode : 0 Volt or Open
