COALAS::LPF-530-8.5W Filter
COALAS::LPF-530-8.5W — a compact low-pass filter (LPF) from Coalas systems, designed for installation on the transmitter (TX output) to reduce the impact of harmonics on the video signal. This filter provides high selectivity for frequencies above the cutoff and stable suppression of unwanted harmonics across a wide frequency range, which positively affects video transmission quality and communication link stability in high-interference environments.
Description and Purpose
The LPF-530-8.5W is ideal for integration into video transmission system transmitter circuits, drone solutions, and modular communication stations. Thanks to its standard impedance and convenient connectors, it is easy to integrate into existing communication circuits without additional adapters. Its compact dimensions and low weight make the filter suitable for use in platforms with limited space.

Attenuation Performance
Below are the measured attenuation values of the filter in various operating ranges, demonstrating its effectiveness in suppressing harmonics that can affect video signal quality:
| Frequency | Attenuation |
|---|---|
| 1.3 GHz | ~40 dBm |
| 1.8 GHz | ~50 dBm |
| 2.4 GHz | ~47 dBm |
| 3.3 GHz | ~46 dBm |
| 4.9 GHz | ~28 dBm |
| 5.8 GHz | ~27 dBm |

Please note the maximum permissible power: 8.5 W. For long-term and stable operation, it is recommended not to exceed this value and to ensure adequate heat dissipation in high-temperature conditions.
Advantages of the COALAS::LPF-530-8.5W filter: high selectivity for harmonics above the cutoff, compatibility with standard SMA connectors, compact size (47 x 12 x 14 mm) and low weight (10 g), making it a convenient component in the equipment kit for video transmission operators and drone detection systems.
Integration: standard 50 Ohm impedance and SMA connectors simplify installation into transmitter circuits without additional adapters. The filter shows effective harmonic suppression in ranges critical for continuous video link operation and enhances communication stability in high-interference environments.
If you need a reliable low-pass filter from a reputable manufacturer for integration into communication stations or drone detection equipment, the COALAS::LPF-530-8.5W from Coalas systems is a practical and rational choice.
