7 GHz RF power detector

19 November 2003 Telecoms, Datacoms, Wireless, IoT

A precision RF power detector designed for monitoring and control applications in wireless communication transceivers, the LTC5532, is an integrated device that is factory trimmed to accurately measure RF signals from 300 MHz to 7 GHz. Manufactured by Linear Technology, this device is suitable for equipment including the 802.11a, b, and g WiFi systems, 5,8 GHz WAN and WLAN radios and other licensed band transceivers.

Its RF input signal range extends from -32 dBm to +8 dBm. The LTC5532 has an on-chip temperature compensated Schottky diode for RF detection. It employs a peak-detection architecture, providing a stable DC output voltage as a function of the RF input power.

The LTC5532 can be powered from a single 2,7 to 6 V supply and draws 500 µA. Besides its applicability in the 900 MHz and 1,9 GHz cellular and PCS infrastructure, its 7 GHz capability opens new uses in the 5,2 GHz to 5,8 GHz bands, including 802.11 multiband a, b, and g, WLAN and WiFi applications. Additional uses include both the 3,5 GHz and the 2,5-2,7 GHz MMDS licensed bands, as well as cable infrastructure equipment, in which RF power level control is important.
