When the power voltage value detected by AD8362 is greater than the reference voltage value, the voltage Vout outputs a high level. When the power voltage value detected by AD8362 is less than the reference voltage value, the voltage Vout uses AD8307 to measure power. Power Measurement Mode: The VOUT and VSET pins are directly connected, and the output voltage is proportional to the logarithm of the effective value of the input power. For every 1dB increase in the input , the output voltage Vout increases by 50 mV, up to Vs 0.1 V. The voltage reading directly reflects the power. Wide Utility: True RMS power detection AD8362 is a power detector with true RMS response. Its measurement results are independent of the waveform and can detect the RF power of complex modulated , including CDMA, W CDMA, 8PSK, QAM, and 0FDM . Specification Item Type: RF Power Meter Material: Aluminum Alloy Model: AD8362 Power Supply Voltage: DC 6V-15V Frequency: 50Hz-3.8GHz Dynamic Range: 65dB Frequency Detector: -75dBm - 16dBm How to Use Take out the product and connect the antenna to use. Package List 1 xRF Power Meter Review: Warning! Do not apply the specified 6V to 15V to this device. You will kill it! - Warning! Do not apply the specified 6V to 15V to this device. You will kill it! I'm on my 3rd one of these now, and that one is finally working and I'm very happy with it, but the first I received is dead having applied 12v to it after assuming that given the description says 'Power Supply Voltage: DC 6V-15V' (and this is also printed on the front of the device) that 12v would be fine and it must have some kind of voltage regulator in it to feed the AD8362 with it's required 5v. With the benefit of hindsight however I should of opened it up and checked, and if you do you see the voltage you apply goes straight to the chip which has a max input of 5.5v according to the AD8362 datasheet. Also beware that there is no external indication of which identical looking terminal is input or output and if you get those the wrong way round when you first connect it and also apply more than 5v at the same time you're going to both fry this device (which results in Vin appearing fully at the output) and maybe fry your RF device too if that was incorrectly connected to the unlabelled output instead of the input. For reference the input is on the left if the Vin pin is facing down/towards you. Don't rely on the sticker orientation as it was a different way up on each of the devices I tried. Suggest opening up the case to check. However, all the being said. If you ignore the seller instructions and pay close attention to the AD8362 datasheet to work out how to power, connect and use it correctly, then the chip itself is great and has the advantage over some of the other similar devices available on desertcart which use the lower spec'd AD8307 or AD8317 instead, that it also gives useful data from 0dbm to +10dbm, while the AD8307 and AD8317 top out at 0dbm max. Wait, I hear you ask. What happened to the 2nd device you tried? Well that actually turned out to be some kind of children's hair band with ribbons on it when I opened the package, which refused to measure RF power regardless of the voltage applied, and I couldn't find a spec sheet for it, so I had to send that back too. But that's all part of the fun of ordering from Chinese importers on desertcart! ## Features - Power Measurement Mode: The VOUT and VSET pins are directly connected, and the output voltage is proportional to the logarithm of the effective value of the input power. For every 1dB increase in the input , the output voltage Vout increases by 50 mV, up to Vs 0.1 V. The voltage reading directly reflects the power. - Wide Utility: True RMS power detection AD8362 is a power detector with true RMS response. Its measurement results are independent of the waveform and can detect the RF power of complex modulated , including CDMA, W CDMA, 8PSK, QAM, and 0FDM . - Controller Mode: Set a reference voltage value at the VSET end. When the power voltage value detected by AD8362 is greater than the reference voltage value, the voltage Vout outputs a high level. When the power voltage value detected by AD8362 is less than the reference voltage value, the voltage Vout uses AD8307 to measure power. - Frequency Band: The working frequency can range from 50Hz to 3.8GHz, suitable for broadband power detection, with flat input and output responses. - High Dynamic Range: The input dynamic range can get to 65dB, and in a 50 day system, its input can range from -75 dBm to 16 dBm. High accuracy and linearity provide an accurate linear output voltage in dB, 50mV per dB. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CLM2BW4F | | Best Sellers Rank | 161,196 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 8 in Logarithmic Amplifiers | | Brand | Fafeicy | | Country Of Origin | China | | Customer Reviews | 3.0 out of 5 stars 1 Review | | Item Type Name | Logarithmic Amplifiers | | Manufacturer | Fafeicy | | Manufacturer Part Number | Fafeicyzm1q87e4ga | | Maximum Supply Voltage | 15 Volts (DC) | | Maximum supply voltage | 15 Volts (DC) | | Minimum Supply Voltage | 6 Volts (DC) | | Minimum supply voltage | 6 Volts (DC) | | Model Number | Fafeicyzm1q87e4ga | | Mounting Type | Freestanding | | Mounting type | Freestanding | | Number of Channels | 1 | | Number of channels | 1 | ## Images ![Fafeicy RF Power Meter and RF Signal Detector - 65dB Dynamic Range Logarithmic Amplifier in Aluminum Alloy Housing DC 6-15V - Image 1](https://m.media-amazon.com/images/I/613ho-02iUL.jpg) ![Fafeicy RF Power Meter and RF Signal Detector - 65dB Dynamic Range Logarithmic Amplifier in Aluminum Alloy Housing DC 6-15V - Image 2](https://m.media-amazon.com/images/I/71qf41e9XML.jpg) ![Fafeicy RF Power Meter and RF Signal Detector - 65dB Dynamic Range Logarithmic Amplifier in Aluminum Alloy Housing DC 6-15V - Image 3](https://m.media-amazon.com/images/I/71LVqRjgEOL.jpg) ![Fafeicy RF Power Meter and RF Signal Detector - 65dB Dynamic Range Logarithmic Amplifier in Aluminum Alloy Housing DC 6-15V - Image 4](https://m.media-amazon.com/images/I/718c7YcY3pL.jpg) ![Fafeicy RF Power Meter and RF Signal Detector - 65dB Dynamic Range Logarithmic Amplifier in Aluminum Alloy Housing DC 6-15V - Image 5](https://m.media-amazon.com/images/I/81MX4lqsGdL.jpg) ## Customer Reviews ### ⭐⭐⭐ Warning!
