Features 【High Linearity & Low Distortion] The AD831 provides +24dBm third-order intermodulation cutoff (IP3) and +10dBm 1dB compression point, which significantly improves processing accuracy for high-fidelity communications and instrumentation scenarios. The active mixer module AD831's dual balanced mixing design effectively suppresses spurious interference and reduces harmonic distortion. 【Low Power LO Input】The dual supply low power mixer AD831 only requires -10dBm local oscillator (LO) drive power, eliminating the need for high power drive circuits, reducing system complexity and heat issues, and avoiding the need for shielding and isolation of traditional passive mixers, lowering overall costs. 【Single/dual power supply compatibility】The dual balanced mixer AD831 supports ±5V dual power supply or single power supply, and all ports are DC-coupled design with on-board isolation capacitors to simplify the circuit connection, which is suitable for rapid deployment and portable device integration. 【500MHz Wideband Input]: Both radio frequency (RF) and local oscillation (LO) inputs support 0.1-500MHz band, the product covers HF/VHF communication and ultrasonic detection and other high-frequency application needs, to meet the needs of multi-scenario frequency conversion. 【Multi-function output configuration]: Single-ended / differential selectable, the single-ended output RF converter module AD831 supports single-ended voltage output (0.1-200MHz) or differential current output (up to 250MHz), the user can flexibly adjust the gain through the external resistor, adapted to different back-end processing modules, strong scalability. 1. 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 2. 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 3. The mixer is designed as a single power supply, RF, IF and LO port with DC isolation capacitor, easy to use 4. The operating frequency of the RF and LO inputs can be as high as 500MHz 5. IF output is single ended voltage output Specification: The AD831 is a low distortion, wide dynamicrange, single chip mixer, suitable for HF and VHF Receiver RF-IF frequency,second mixer in base station, DC-baseband conversion, quadrature modulationand demodulation, and ultrasound imaging, frequency detection and otherapplications.

There is no corresponding shielding andisolation problems, therefore, compared with the passive mixer to improve theperformance of the system, reduce the system cost. The mixer is designed as a single powersupply, RF, IF and LO port with DC isolation capacitor, easy to use. The operating frequency of the RF and LOinputs can be as high as 500MHz. IF output is single ended voltage output. With 250 MHz output bandwidth. A single resistor connected between pinsOUT and FB is used to set the gain. The amplifier has low DC offsetcharacteristics, so it can be used in DC-baseband frequency conversion andquadrature amplitude demodulation. When the mixer's output amplifier and theoptimum source impedance, the SSB noise figure of the mixer is 10.3dB at 70MHz. Different from the passive mixer, there isno insertion loss, no need external duplex device, Package List
