Accurate RF Measurement: AD8317 detector logarithmic amplifier provides accurate RF measurement. The measurement accuracy is better than ±1 dB in a dynamic range greater than 50 dB, and a power controller with adjustable power amplifier or variable gain amplifier is provided at the output..
Wide Operating Frequency Range: The wide operating frequency range from 1M HZ to 10G Hz supports all cellular standards, broadband wireless standards and private dedicated systems in frequency bands..
Shielding Case: With shielding case and antireverse protection diode in the 3V to 5V power supply voltage range..
Sturdy & Durable: 1.6mm thick PCB double panel, sturdy and durable, long service life, large heat dissipation area, stable operation, long running time, easy to use, good performance, small size, easy to carry and store..
Working Temperature: AD8317 provides better accuracy, temperature stability, and 5 ns fast output response in the temperature range of 40 ℃ to + 85 ℃, and is used for RF burst detection at 125 MHz..

...Module gain: When there is no solder slip, the AD620 will zoom by 10 times by default, and the AD623 will zoom by 20 times by default. During welding slip, AD620: G=1+50K/Rg, AD623: G=1+100K/Rg ✭Maximum magnification of the module: more than 2000 times (actual measurement), due to the large gain of the waveform frequency band, it is recommended to use multi-stage amplification with high gain ✭Fixed output voltage: 5V-10V (default delivery 5V).
♥ Other parameters: ✭Common mode rejection ratio: AD620: 100dB (minimum, G=10).
AD623: 90dB (minimum, G=10) ✭Input bias current: AD620: 1.0nA (max).
AD623: 23nA (max) ✭Input offset voltage: AD620: 50μV (max).
AD623: 200μV (max) ✭Input offset offset: AD620: 0.6μV/°C (max).
AD623: 2μV/°C (max) ✭Input voltage noise: AD620: 9nV/√HZ (1KHZ).
♥Precautions: 1. The power supply of the module is a single power supply, and the voltage cannot exceed 26V 2. Since the module is a high-precision device, to avoid unnecessary interference, it is recommended to use a linear power supply for power supply 3. It is recommended to use SMA to BNC line input and output signal for the output signal. Compared with the observation effect, poor contact or inferior wire may cause signal att....

...IOUS PORTS-- There is no corresponding shielding and isolation problems, therefore, compared with the passive mixer to improve the performance of the system, reduce the system cost. The mixer is designed as a single power supply, RF, IF and LO ports with DC isolation capacitor, easy to use..
POWERFUL-- The operating frequency of the RF and LO inputs can be as high as 500MHz. IF output is single ended voltage output. With 250 MHz output bandwidth. A single resistor connected between pins OUT and FB is used to set the gain..
EASY TO USE-- When the mixer's output amplifier and the optimum source impedance, the SSB noise figure of the mixer is 10.3dB at 70MHz. Different from the passive mixer, there is no insertion loss, no need external duplex device, and no need passive termination for AD831..
APPLICATION-- The AD831 is a low distortion, wide dynamic range, single chip mixer, suitable for HF and VHF Receiver RF-IF frequency, second mixer in DMR base station, DC-baseband conversion, quadrature modulation and demodulation, and ultrasound imaging, frequency shift detection and other applications..
FEATURE-- The AD831 has provide +24 dBm third-order intermodulation intercept point, realization of -10 dBm LO power, without the need for a high power LO drive..
