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 and small size for easy embedded installation..
Sensing range: ≤100 degree cone angle, 3-5 meters.

The Klipsch RSA-500 is a single channel amplifier designed to power a passive subwoofer (a subwoofer that has no internal amplifier).
Primarily designed for use with the Klipsch RW-5802 and RW-5101-C in wall subwoofers, it also features custom settings for the AW-800-SW outdoor subwoofer.
This amplifier pumps out 300 watts into an 8-ohm load (one subwoofer module) and 500 watts into a 4-ohm load (two subwoofer modules).
The RSA-500 offers standard input/output connectivity that will support any type of system.
Rack ears are included for fast and secure placement into any standard 19-inch rack.

-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.
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.
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.
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.
Low Distortion and Wide Dynamic Range: AD831 is a low distortion, wide dynamic range, single chip mixer, very practical.
