Feature: Multiple detection functions: Supports envelope detection, amplitudes modulation detection, and diodes detection, with a multifunctional to meet different needs. Good sensitivity: Use double voltages detector (consist of two reverse microwaved diodes), the sensitivity is twice that of single tube detector (6dB), with highly sensitivity. Efficient Demodulator: detectors have efficient demodulation performances and can accurately original information. Strong stability: Craft with technology,with stable performances and ensures the accuracy of demodulation. Accurate amplitudes modulation: The is simple, and the amplitudes modulation detection function can accurately adjust the amplitudes, improving and clarities. Specification: Printed Circuit Board Size: about 44x10mm/1.73x0.39inch Input: up to 20dBm (burnsout power): Linears range<10dBm Detection output: defaults to positive (if you need output, you can us, change the welding direction of diodes by yourself) Working frequency: 0.1-3200MHz Filtering: R=10K, C=1nF; (Two parallelled components of the output port) Note: If you want to work at a lower frequency, you can increase the output capacitance. If you want a faster response speed, you need to reduce the electrical capacity. You can configure it according to your own needs. Please allow 1-2cm errors due to manual measurement. Please allow for slight color differences due to different display resolution. Package includes: 1x Detector
