Simplified High Frequency Tuner
Bluetooth® * ZigBee™ * Cellular Telephones * Wireless LAN
Cable Modems * Police & Fire Radio * AM/FM/XM Consumer Radio
The Simplified High Frequency Tuner technology uses an efficient low-IF architecture that can move your company's wireless
products higher up the price/performance curve.
Whether you're in the business end of things or doing design work, you know
how much component costs can hurt your company's bottom line, especially in the
cost-sensitive consumer products market.
-
Reduce PLL costs with a Doubled PLL Step Size that works
by making selective use of upper and lower low-IF frequency ranges; or
-
Relax component tolerances with Adaptive Image
Avoidance to "dance around" strong interference and thus make the most of
limited image rejection;
-
Use less-expensive silicon to fabricate your
analog circuitry by taking advantage of a Low-IF Frequency Arrangement that
offers efficient image rejection, 1/f noise immunity, and immunity from
half-IF and self-mixing spurs;
-
Maintain image rejection while relaxing your tolerances
for I,Q channel matching by digitally correcting with an efficient
Variable-Phase Hilbert Transform; and
-
Make compact and high-performance delta-sigma
A/D conversion practical at IF by using efficient Single-Stage One-Bit
Decimation Filtering.
