Dual RF Power Detector Capable of 11GHz Operation Addresses Multi-Band Applications
MILPITAS, CA - March 23, 2006 - The LTC5533 dual channel RF power detector from Linear Technology is the first in the industry to reach the 11GHz range, making it ideal for multi-band WiFi, WiMAX and other radio applications. Covering RF applications ranging from 300MHz to 11GHz, the dual channel LTC5533 supports multiple frequencies in one package, as needed for multi-band applications. The device draws extremely low power of 500uA per detector, significantly reducing system power demands.
The LTC5533 contains temperature compensation circuitry that provides exceptionally stable and accurate measurements over the full range of temperature extremes. The device includes buffer amplifiers and is housed in a tiny, space-saving surface mount package. The LTC5533 features 40dB dynamic range and 45 dB channel-to-channel isolation.
The LTC5533 dual RF power detector is ideal for a range of applications, including dual-band WiFi PA power control, dual-band cellular/WiMAX basestations, point-to-point microwave links, transmit PA forward and reverse power measurements and low cost AM detector/receivers.
The LTC5533 is available from stock in a compact 4mm x 3mm DFN package, priced at $3.20 each in 1,000-piece quantities.
