Optimize RF signal performance with this 2030MHz RF bandpass filter module built around the AD831 active mixer, engineered to deliver low distortion and wide dynamic range in advanced RF and IF down conversion tasks. Perfect for VHF receivers, DMR base stations, Doppler shift detection, and quadrature modulation/demodulation, this single-supply module eliminates the need for bulky passive duplexers or high-power drivers. With a +24dBm third-order intercept point and low 10dBmL0 power consumption, the module ensures efficient signal mixing while minimizing system complexity and cost. Designed with DC isolation capacitors at the RF, IF, and LO ports, this RF module is easy to integrate into existing setups, making it for baseband conversion and signal filtering in both commercial and experimental projects.

Features:
*The AD831 is a low distortion, wide dynamic range, single chip mixer for applications such as RF-IF down conversion in HF and VHF receivers, second mixer in DMR base stations, DC-to-baseband conversion, quadrature modulation and demodulation, and Doppler shift detection in ultrasound imaging
*The AD831 provides a +24dBm third-order intercept point and achieves -10dBmL0 power consumption, eliminating the need for a high power L0 driver and the associated shielding and isolation issues, thereby improving system performance and reducing system cost compared to passive mixers.
*The mixer is designed to operate from a single supply and has DC isolation capacitors at the RF, IF, and L0 ports for ease of use. The RF and L0 inputs can operate up to 500MI. The IF output is a single-ended voltage output. It has a 250MHz output bandwidth. A single resistor connected between pins 0UT and FB is used to set the gain. The has low DC offset characteristics, so it can be used in DC-coupled applications such as DC-to-baseband conversion and quadrature amplitude demodulation.
* The SSB noise figure of the mixer is 10.3dB at 70MHz when the mixer's output and optimum source impedance are used. Unlike passive mixers, the AD831 has no insertion loss, does not require an external duplexer, and does not require passive termination.
