RF Detector IC 802.11a/b/g/WiFi, 802.16/WiMax, WLAN 300MHz ~ 11GHz -32dBm ~ 12dBm ±1dB 12-WFDFN Exposed Pad

Specification:

Description:

The LTC® 5533 is a dual channel RF power detector for RF applications operating in the 300MHz to 11GHz range. Two independent temperature compensated Schottky diode peak detectors and buffer amplifiers are combined in a small 4mm × 3mm DFN package. The RF input voltage is peak detected using on-chip Schottky diodes. The detected voltage is buffered and supplied to the VOUT pins. A power saving shutdown mode reduces current to less than 2µA/channel. The initial output starting voltages can be precisely adjusted using the VOS pins. The LTC5533 operates with input power levels from –32dBm to 12dBm.

Application:

■ PA Forward and Reverse Power Monitor

■ Dual PA Transmit Power Control

■ 802.11a, b, g, 802.15, WiMAX

■ PA Linearization

■ Fixed Wireless Access

■ RF Power Alarm

■ Envelope Detector
