Single Power Supply: The mixer module is designed to be powered by a single power supply, and the RF, IF and LO ports have DC isolation capacitors for easy use.
10.3dB SSB Noise Figure at 70MHz: With the output amplifier and optimal source impedance of this mixer module, the SSB noise figure is 10.3dB at 70MHz. There is no insertion loss, no external duplexer, and no passive termination.
Low Distortion and Wide Dynamic Range: AD831 is a low distortion, wide dynamic range, single chip mixer, very practical.
-10dBm LO Power Consumption: Provides +24dBm third order intercept point, can achieve -10dBm LO power consumption, without high power LO drivers, there are no corresponding shielding and isolation problems, can improve system performance and reduce costs.
Wide Application: Suitable for applications such as RF‑IF down conversion in HF and VHF receivers, second mixer in base stations, DC baseband conversion, quadrature modulation and demodulation, and Doppler shift detection in imaging.

AM312 Human Sensing Module: Based on passive body infrared technology digital intelligent automatic control products, high sensitivity, reliability, widely used in various types of automatic induction electrical equipment..
Low power consumption, small size, easy to install..
Internal use of digital signal processing, pit interference strong..
Repeatable trigger mode: that is, after the induction output is high, in the delay period, if the body in its induction range of activities, the output will remain high until the delay after the person to become Low level. (Ie, the sensing module automatically detects a delay period after each activity of the human body, and takes the last active time as the starting point for the delay time)..
Sensing range: ≤100 degree cone angle, 3-5 m.
(required depending on the lens) Working temperature: -20 to + 60 ℃.
