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

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

The AD831 is a low distortion, wide dynamic range, single chip mixer, suitable for HF and VHF Receiver RF-IF frequency, second mixer in DMR base station, DC-baseband conversion, quadrature modulation and demodulation, and ultrasound imaging, frequency move detection and other applications.
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.
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.
The mixer is designed as a single power supply, RF, IF and LO ports with DC isolation capacitor, easy to use.
The amplifier has low DC offset characteristics, so it can be used in DC-baseband frequency conversion and quadrature amplitude demodulation.

Terminates and cuts all cable types into panels and jacks in a single stroke.
Increased HI/LO impact force to meet demands of new cable types and AWG sizes: LO= 30 lbs, HI= 40 lbs.
Soft, rubber-embedded non-slip grip and cushioned heel for comfort in the palm of your hand.
New impact system reduces time and effort.
