LTC5582 datasheet

 

Description

The LTC5582 is a 40MHz to 10GHz RMS responding power detector.  It  is  capable  of  accurate power  measurement of an AC signal with wide dynamic range, from –60dBm to 2dBm depending on frequency. The power of the AC signal in an equivalent decibel-scaled value is precisely converted into DC voltage on a linear scale, independent of the crest factor of the input signal waveforms. The LTC5582 is suitable for precision RF power measurement and level control for a wide variety of RF standards, including LTE, WiMAX, W-CDMA, CDMA2000, TD-SCDMA, and EDGE.

 

Application Circuits :
components

The DC output is buffered with a low output impedance amplifier capable of driving a high capacitance load. Consult factory for more information. The part is packaged in a 10-lead 3mm ×3mm DFN. It is pin-to-pin compatible with the LT5570.

Features

1. Frequency Range: 40MHz to 10GHz

2. Linear Dynamic Range: Up to 57dB

3. Accurate RMS Power Measurement of High Crest Factor Modulated Waveforms

4. Exceptional Accuracy Over Temperature: ±0.5dB (Typ)

5. Low Linearity Error within Dynamic Range

6. Single-Ended or Differential RF Inputs

Applications:

1. RMS Power Measurement

2. PA Power Control

3. Receive and Transmit Gain Control
