2.4 to 3-3.5 GHz RF Frequency Up Down Converter for COFDM, UAV links, wireless video, and RF front-end systems
Table of Contents
Overview
The 2.4 to 3–3.5 GHz RF Frequency Up/Down Converter is a high-performance frequency translation module designed for professional wireless video transmission, COFDM systems, and RF front-end integration. By shifting 2.4 GHz signals to the 3–3.5 GHz band—or vice versa—it ensures reliable communication in congested RF environments and supports long-range, low-latency wireless links. The compact, low-noise design makes it ideal for drone, broadcast, industrial, and security applications.

FAQ
Q: Can you explain more about dropping down to 600 MHz to work with your cofdm transmitter and receiver module?
A: Certainly. Our transmitter platform supports a very wide operating frequency range of 175–3500 MHz, and in some configurations even 175–6000 MHz. However, the internal tuner/demodulator chipset used in the receiver is designed to directly process signals only within approximately 175–860 MHz. This frequency range corresponds to the standard European DVB-T broadcast spectrum, where the receiver operates natively and most efficiently.
When the transmission frequency is above 860 MHz — for example in bands such as: 1.2 GHz, 2.4 GHz,5.8 GHz. the receiver cannot directly demodulate the RF signal at those frequencies. In these cases, a frequency downconverter is required.The downconverter shifts the higher RF frequency down into the receiver’s supported 175–860 MHz range before demodulation. Once converted, the receiver processes the signal normally using the DVB-T demodulator.
| Operating Frequency | Receiver Operation |
|---|---|
| 175–860 MHz | Direct reception |
| 860–6000 MHz | Requires external downconverter |
This is a standard approach used in many professional RF, broadcast, and COFDM/DVB-T systems, allowing very wide frequency coverage while maintaining stable and reliable DVB-T reception performance.
1. Can the frequency range be customized?
Yes. Both the input/output frequencies and LO can be customized based on your system requirements.
2. Does it support COFDM video transmission systems?
Absolutely. The converter is designed for COFDM-based UAV and long-range video transmission.
3. Can it reduce interference from other 2.4 GHz devices?
Yes. Shifting the operating band to 3–3.5 GHz helps bypass crowded 2.4 GHz environments.
4. Is the module suitable for drone applications?
Yes. It features compact size, low power consumption, and stable RF performance.
5. Can you provide OEM/ODM customization?
We can customize connectors, gain, housing, and frequency ranges based on your project needs.
When placing an order, please let us know your required conversion gain, LO (local oscillator) frequency, and any other custom parameters.
