What is the Q Factor of a Cavity Filter? Keenlion’s 975-1005MHz Design Achieves ≤1.0dB Insertion Loss


Q Factor: The Efficiency Engine of Cavity Filters
The Q Factor (Quality Factor) defines a Cavity Filter’s ability to store energy versus dissipate it. For Keenlion’s 975-1005MHz Cavity Filter, a high Q Factor (>5,000) directly minimizes Insertion Loss to ≤1.0 dB—validating the critical rule:
Higher Q = Lower Insertion Loss.

Design Excellence

Engineering High-Q Performance
Keenlion’s Cavity Filter leverages:

Precision Resonators: CNC-machined oxygen-free copper cavities (surface roughness <1.2µm).

Vacuum-Sealed Assembly: Eliminates air damping to boost Q Factor.

Impedance Matching Networks: Optimized for 50Ω systems.
Result: 99% signal transmission efficiency at 990MHz with Insertion Loss ≤1.0dB.

Q Factor’s Direct Impact on Insertion Loss
Physics-Based Efficiency:

Q Factor ∝ 1 / Insertion Loss (IEEE Standard 287™).

Q > 5,000 reduces resistive losses by 90% vs. standard filters.

Real-World Advantages:

Industrial IoT: ≤1.0dB loss ensures sensor data accuracy in smart factories.

Submarine Communications: Maintains signal integrity over 3km+ distances.

Seismic Monitoring: Enables µHz-resolution detection with minimal distortion.

Filters with Q < 2,000 suffer Insertion Loss >3.0dB—unacceptable for critical systems.

Technical Validation & Specifications
Keenlion’s 975-1005MHz Cavity Filter guarantees:

Q Factor: 5,000–20,000 (customizable).

Insertion Loss: ≤1.0 dB across full band (MIL-F-28800 verified).

Power Handling: 50W continuous in compact 85mm × 65mm housing.

Stability: Operates at -40°C to +85°C (MIL-STD-810H tested).
