ADI RF Power Detectors

Envelope Detectors

Envelope detector is a key component used to extract the signal envelope in RF systems, which can respond quickly to changes in signal amplitude. They are characterised by the following features:

Ultra-wide dynamic range: some models can reach more than 60dB, suitable for high dynamic range signal processing

Fast response time: nanosecond response time to meet the needs of real-time signal processing

Low temperature drift: Optimised temperature compensation design ensures measurement stability.

Small package options: SOT-23, QFN and other compact packages are available to save PCB space.

Typical applications include: power amplifier (PA) linearisation control, automatic gain control (AGC) loops, radar pulse detection, and signal monitoring for wireless communication systems.

Logarithmic Detectors

ADI logarithmic detectors provide an output voltage that is logarithmic to the power of the input signal and are ideal for accurate measurement of signals over a wide dynamic range. Key features include:

Wide frequency range: covers low frequency to millimetre wave bands (up to 40GHz)

Highly accurate logarithmic coherence: typical error less than ±1dB

Integrated temperature compensation: Built-in temperature sensor and compensation circuitry

Single power supply: simplifies system power design

Widely used in base station power monitoring, spectrum analysers, electronic warfare systems and test and measurement equipment, these devices are particularly suited to applications where accurate power measurement is required.

RMS Detectors

RMS detectors accurately measure the true power of complex modulated signals and are an essential component of modern communication systems. Key features include:

True RMS response: accurately measures the power of various modulated signals (e.g. QAM, OFDM)

Wide bandwidth: supports RF signals up to 6GHz

High linearity: excellent linearity performance ensures measurement accuracy

Low-power design: suitable for portable and battery-powered devices

Main application scenarios include: 5G base station power calibration, microwave link monitoring, satellite communication systems, and laboratory test equipment.
