Overview
The 5.8GHz to 1.2GHz Drone Downconverter is a high-performance frequency translator designed for professional drone video and FPV transmission systems.
It receives 5.8GHz signals via a top-mounted omni antenna, cleanly downconverts the signal to the 1.2GHz band using a stable 4500MHz PLL local oscillator, and transmits through a high-power amplifier and bottom-mounted patch antenna.
This solution significantly extends transmission range and improves penetration while maintaining compatibility with existing 1.2GHz ground receiving equipment.
Features
- Precise Frequency Conversion: 5.8GHz (5658–5917 MHz) down to 1.2GHz (1158–1417 MHz)
- Ultra-Low Noise Figure: 1.5dB NF with high-gain LNA for excellent signal quality
- High Output Power: +27dBm (500mW) with integrated BPF and Power Amplifier
- Stable PLL Synthesizer: 4500MHz precision LO for high frequency stability
- Optimized RF Architecture: Top RX + Bottom TX antenna placement to minimize self-interference
- Clean Signal Output: High-performance filtering for low spurious emissions
- Compact & Lightweight Design: Suitable for various drone platforms

FAQ
Q: What is the main purpose of this downconverter? A: It converts 5.8GHz video signals to 1.2GHz, providing longer transmission distance, better obstacle penetration, and compatibility with existing 1.2GHz receivers.
Q: How much power does it output? A: It delivers a clean +27dBm (500mW) output, suitable for medium to long-range flights.
Q: Is the frequency stable? A: Yes. It uses a professional PLL synthesizer at 4500MHz, ensuring excellent frequency stability even under vibration and temperature changes.
Q: Can I use my existing 1.2GHz receiver? A: Absolutely. This is one of the main advantages — no need to replace your ground station equipment.
Q: Do you offer customization? A: Yes. We support custom frequencies, power levels, mechanical design, and OEM services for drone manufacturers and system integrators.
Q: What antennas are recommended? A: 5.8GHz omni antenna on top and 1.2GHz patch antenna on the bottom, as shown in the system diagram.
