Precise RF Power Measurement

About this item

The Walfront RF Signal Power Meter Logarithmic Detector is engineered for precise RF signal power detection across a broad frequency range of 1MHz to 600MHz. It accurately converts RF signals into a DC voltage output, with the output voltage being logarithmically proportional to the input signal's power, ranging from -74dBm to +18dBm. This makes it a versatile component for various applications including RF signal detection, power measurement, and environmental field strength analysis.

This detector is widely utilized in automatic gain control (AGC) and automatic level control (ALC) systems. Its design allows for integration into a 1mW to 1kW RF power meter after appropriate transformation. Key specifications include a working frequency of 1MHz-600MHz, measuring power from -74dBm to +18dBm, an output voltage range of 0-2.5V, and a typical detection slope of 25mV/dBm. It operates on a power supply voltage of 6-15V and features an SMA-female RF input connector.

For engineers and hobbyists in India, this imported logarithmic detector offers a reliable solution for RF analysis. It is designed for surface mount applications and requires a 6-15V DC power supply. The unit is factory-sealed and imported per order, ensuring authenticity. All customs duties and GST are included in the price, with delivery via ExpressBox tracked shipping.

Key Features

  • The detector is is used for RF signal power detection of frequency range between 1MHZ and 600MHZ
  • It can detect a rf signal of power from -74dBm to 18dBm, and convert the RF signal into a DC voltage output
  • The higher radio frequency signal range or power is, the higher output voltage will be; output voltage is proportional to logarithm of input signal range
  • Widely used for RF signal detection, signal power measurement, environment field strength detection, can also be used as a part of automatic gain control and automatic level control
  • It can be made into 1mw ~ 1kw RF power meter after appropriate transformation

Why choose this product

Precision RF Signal Analysis

This Walfront logarithmic detector provides accurate RF signal power measurement from -74dBm to 18dBm across a 1MHz to 600MHz range. Its output voltage is logarithmically proportional to input power, making it essential for applications requiring precise signal level monitoring. Unlike basic detectors, its design allows for integration into sophisticated systems like automatic gain control and automatic level control, or even custom RF power meters capable of handling up to 1kW. This imported component ensures reliable performance for critical RF engineering tasks.

Who It's For vs. Who Should Skip It

Ideal for electronics engineers, RF technicians, and hobbyists in India working on radio frequency projects, signal analysis, or building custom test equipment. It's perfect for those needing to measure signal strength or integrate logarithmic detection into control systems. Skip if you require a detector for frequencies significantly above 600MHz or need to measure power levels outside the -74dBm to +18dBm range, as this unit is specifically calibrated for this spectrum and power band.

How to use

  • Connect Power Supply — Apply a stable DC power supply voltage between 6V and 15V to the VCC pin. Ensure the power source is reliable to prevent fluctuations that could affect measurement accuracy.
  • Connect RF Input — Connect the RF signal source to the SMA-female input connector. Ensure a secure connection to prevent signal leakage or impedance mismatch, which could distort readings.
  • Measure Output Voltage — Connect a voltmeter or oscilloscope to the OUT pin to measure the DC output voltage. This voltage will be proportional to the logarithm of the input RF signal's power, allowing for power level determination.
