Chipidea unveils a comprehensive, multi
standard WLAN/WiMAX AFE portfolio, culminating several years of
market-driven developments and leveraging deep knowledge of Wireless
LAN applications.
 Brief Description
CHIPIDEA´s WLAN/WiMAX Analog Front Ends are complete AFEs for
baseband–RF interfacing. They include two main signal paths,
I&Q ADC and I&Q DAC, auxiliary converters and a flexible clock
generation unit.
The input and common-mode ranges are programmable for inter-operation
with most available radio transceivers. Each converter has an
individual power-down control. Complete power-down mode provides less
than 10µA of standby current.
CHIPIDEA’s AFEs go beyond the simple assembly of independent
data converters and include shared reference and biasing functions to
optimize area and define loopback test-modes to decrease production
test costs.
