The LT5581IDDB#TRPBF is a precision RMS power detector from Analog Devices, designed for applications requiring accurate RF power measurement across a wide frequency range of 10MHz to 6GHz. This monolithic IC offers a 40dB log-linear dynamic range, capable of detecting modulated signals with crest factors up to 12dB. Its output is a DC voltage linearly proportional to the RF input power in dBm, making it suitable for power measurement and control in various wireless standards like LTE, WiMAX, and GSM/EDGE.
The device operates from a supply voltage of 2.7V to 5.25V and consumes a low current of 1.4mA at 3.3V. It features a fast response time with a 1μs rise and 8μs fall. The LT5581IDDB#TRPBF is housed in a compact 8-DFN (3x2) surface-mount package, ideal for space-constrained designs. Its accuracy over temperature and single-ended RF input simplify integration into infrastructure power amplifier level control, pico-cells, femto-cells, and wireless repeaters.
Key specifications include an input power range from -34dBm to +6dBm at 2.14GHz and an accuracy of ±1dB. The device is designed for reliable performance within an operating temperature range of -40°C to 85°C.
