AL2230S
2.4GHz 802.11b/g Single Chip Transceiver
2 Description
AL2230S is a highly integrated RF transceiver IC for 2.4GHz band 802.11b/g applications,
and combines all functions of the transceiver in a single chip. AL2230S also integrates
on-chip PA and PLL to help you to minimize the use of external components to design an RF
subsystem.
The receive path implements a direct down-conversion architecture to eliminate additional IF
filters. It includes a single-ended input Low Noise Amplifier (LNA), a direct down-conversion
mixer with DC-offset cancellation, and a variable gain amplifier with a baseband low-pass
filter.
The transmitter consists of a direct up-conversion quadrature modulator with a baseband low
pass filter, a variable gain amplifier, a power amplifier and a power detector to complete the
whole transmit path function.
A power-on calibration procedure is established to correct the TX DC offset and filters
mismatch.
These functions are housed in a 48-pin QFN package.
