915 Generation AD831 High Frequency RF Mixer Module Frequency Converter

The AD831 is a low distortion, wide dynamic range, single chip mixer, suitable for HF and VHF Receiver RF-IF frequency, second mixer in base station, DC-baseband conversion, quadrature modulation and demodulation, and ultrasound imaging, frequency shift detection and other applications.
The AD831 has +24 dBm third-order intermodulation , realization of -10 dBm LO power, without the need for a high power LO drive. There is no corresponding shielding and isolation problems, therefore, compared with the passive mixer to 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. 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.
The amplifier has low DC characteristics, so it can be used in DC-baseband frequency conversion and quadrature amplitude demodulation. When the mixer's output amplifier and the best source impedance, the SSB noise 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. Specification:
