RF Mixer Module, Easy to Use, DC Offset, -10 dBm LO Power, HF VHF Receiver, Quadrature Demodulation, 1-500MHz RF IF LO, 24 dBm 3rd Order, for DC Baseband Conversion, Single-Ended Supply

Description

Product Overview

The RF Mixer Module is engineered for engineers and hobbyists who need a reliable, high‑performance mixing solution for HF and VHF applications. It features an intuitive DC offset adjustment that eliminates the need for external biasing circuits, allowing users to achieve optimal mixer balance with minimal effort. Operating with a low local‑oscillator (LO) power of -10 dBm, the module reduces power consumption while maintaining excellent conversion efficiency.

Covering a broad frequency span from 1 MHz to 500 MHz across the RF, IF, and LO ports, the mixer supports a wide variety of signal environments, from low‑frequency baseband up to VHF band reception. The design delivers a third‑order intermodulation (IM3) product of 24 dBm, ensuring that spurious signals remain well below the noise floor in demanding communication systems. The module is supplied with a single‑ended power rail, simplifying board layout and reducing component count.

Key specifications include:

• Frequency range: 1 MHz – 500 MHz (RF, IF, LO)
• LO power requirement: -10 dBm
• Third‑order intercept point (IP3): 24 dBm
• DC offset adjustment: 0 – 200 mV (continuous)
• Supply voltage: 5 V single‑ended

Usage

This mixer is ideally suited for a range of practical scenarios. In amateur radio transceivers, it enables clean quadrature demodulation for SSB and CW modes, delivering clear audio with minimal distortion. For laboratory test equipment, the wide frequency coverage allows the module to serve as a core component in spectrum analyzers, signal generators, and frequency converters. Its low LO power requirement makes it compatible with battery‑powered portable receivers, extending operational time without sacrificing performance.

Field engineers working on remote sensing or telemetry systems will appreciate the module’s robust construction and stable temperature characteristics, which ensure consistent operation in harsh environments. The easy DC offset control simplifies calibration in the field, reducing setup time and the risk of misadjustment. Additionally, the single‑ended supply architecture eases integration into existing PCB designs, requiring only a standard 5 V rail and minimal external components.

FAQ

What is the purpose of the DC offset adjustment?

The DC offset control allows you to fine‑tune the mixer balance, minimizing even‑order distortion and improving overall conversion efficiency without adding external components.

Can the module operate with a single‑ended 5 V supply?

Yes, the mixer is designed for a single‑ended 5 V power rail, simplifying PCB layout and reducing the number of required power regulators.

Is the mixer suitable for high‑frequency VHF applications?

Absolutely. With a top frequency of 500 MHz, the module comfortably covers the entire VHF band, making it ideal for receivers, transceivers, and signal processing chains in that range.

How does the third‑order intercept point affect performance?

A higher IP3 (24 dBm) means the mixer can handle stronger signals before intermodulation products become problematic, resulting in cleaner output and better dynamic range.

What warranty and support are provided?

We offer a two‑year warranty against manufacturing defects and provide technical assistance through email and phone to help you with integration, troubleshooting, and optimization.
