Mixer Module, Bandwidth Mixing 0.1‑500MHz High Frequency Transducer -10dBm for Quadrature Modulation for Base Station for HF VHF Receiver

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.

♥Basic Features: ✭Module Name AD620 Instrument Programmable Amplifier ✭Module size:50mm * 50mm ✭Module power supply: 5V-24V ✭Module input signal type: single-ended signal or differential signal ✭Module signal input and output range: the input signal range is within 100 microvolts of the power supply, and the output signal range is within the power supply ✭Module bandwidth: AD620: 120KHz (G=100), AD623: 800KHz (G=1), AD620/623 is lower than 50KHz at high gain, and higher than 1MHz at low gain.
♥ Other Features: ✭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 cur....

photosensitive resistance module's most sensitive to ambient light, commonly used to detect environment around the brightness of the light, or MCU trigger relay module, etc..
module in the environment light intensity than set threshold, output high level DO end, when the environment light intensity more than set threshold, the DO output low level.
the DO output can be directly connected to microcontroller, through single chip microcomputer to detect the high and low level, thus to detect the environment light intensity change.
the DO output can be directly driven our relay module, which can form a light-operated switch..

SINGLE-CHANNEL: TLV3501 is a single-channel high-speed push-pull output comparator, delay is 4.5ns, supply voltage: + 2.7V to + 5.5V.
FRONT SHAPING MODULE: This module can be for a wide range of voltage signal shaping period, as the frequency, phase difference time domain measurements and other front-end conditioning module.
CMOS AND TTL: Rail-to-rail output can directly drive a CMOS or TTL logic.
EASY TO OPERATE: Without threshold setting, the sine wave, square wave and triangular wave can be transformed into square wave, which can be used easily without debugging.
GREAT EXTENSIBILITY: At the same time, it has great extensibility, just change a small amount of the original.
