LX5563
2.4 - 2.5 GHz LNA With Bypass
Description
The LX5563 is a low noise amplifier (LNA) for WLAN
applications in the 2.412 to 2.472 GHz frequency
range. It operates with a single voltage supply of 3.3V,
and features both high gain and bypass modes.
The LNA is fully matched on both the input and output
ports; no external inductors or matching is required. It
includes all bias circuitry and operates with a digital
control signal. Only one external bypass capacitor on
the supply line is required.
The LNA is packaged in a 1.5x1.5x0.5 mm dual-flat
no-leads (DFN) package.
