Air Coil Inductor BC

Broadband Conical Air Coil Inductors with Flying Leads – High-Frequency Performance up to 40 GHz

Engineered for precision in ultra-wideband and high-frequency systems, our conical Air Core Inductor series delivers exceptional flat bandwidth performance from 10 MHz to 40 GHz. These broadband inductors are specifically designed to reduce magnetic saturation in bias tees and RF circuits, ensuring consistent impedance stability across extreme operating conditions—from -40°C to +125°C. The innovative flying leads design offers unmatched flexibility in mounting angle and positioning, minimizing parasitic capacitance and enhancing signal integrity in mmWave and radar applications.

Key Features

• Flat bandwidth response up to 40 GHz ensures reliable operation in high-speed analog and digital RF environments where traditional inductors fail due to resonance effects or saturation issues.
• Flying leads enable precise mechanical alignment without soldering constraints—ideal for phased array antennas, satellite transceivers, and test equipment requiring dynamic tuning.
• Temperature resilience across industrial-grade ranges (-40°C to +125°C) makes these air core inductors suitable for aerospace, defense, and telecom infrastructure under thermal stress.
• Low loss and high Q factor at millimeter-wave frequencies support narrow-band filtering, biasing networks, and impedance matching in 5G NR, Ka-band, and E-band systems.

Unlike conventional PCB-mounted inductors, this air coil inductor avoids the limitations of fixed geometries and parasitic coupling. Its open-air structure reduces dielectric losses and prevents core saturation even under high current densities—a critical advantage in power-efficient designs for modern RF front-ends. Whether deployed in a compact bias tee module or integrated into a multi-channel phased-array system, these components maintain consistent performance over time, making them ideal for mission-critical applications in telecommunications, defense electronics, and scientific instrumentation.

Applications

• Bias tees and RF amplifiers benefit from stable impedance curves that prevent signal distortion caused by air core inductor saturation at high frequencies.
• Phased-array antennas in military radar and 5G base stations use flying lead configurations for accurate beamforming control and minimal phase error.
• Satellite communication systems leverage the low insertion loss and wide bandwidth for Ka-band downlink/uplink modules, improving link budget efficiency.
• Test and measurement setups employ tunable versions of this inductor for narrow-band filtering and calibration tasks up to 40 GHz.

Users report significant improvements in signal clarity and reduced harmonic distortion when replacing standard ferrite-core inductors with these air coil variants. Engineers working on next-generation wireless infrastructure appreciate the ability to fine-tune inductance values through physical adjustment rather than relying on pre-defined component libraries. In lab environments, researchers have noted enhanced repeatability in measurements thanks to the absence of temperature-induced drift commonly seen in ceramic or powdered iron cores.

Frequently Asked Questions

• What is the difference between an air core inductor and a Ferrite Core inductor?
  Air core inductors offer superior linearity and lower hysteresis losses compared to ferrite cores, which can saturate easily under high current or frequency. This makes them more suitable for high-frequency applications like RF biasing and mmWave systems.
• How does the flying leads design improve performance?
  By eliminating rigid solder joints, flying leads allow for better mechanical adaptability, reducing stray capacitance and enabling optimal placement in tight spaces such as microwave assemblies or stacked PCBs.
• Are these inductors suitable for space-grade applications?
  Yes, their broad temperature tolerance and radiation-hardened construction make them appropriate for satellite payloads, deep-space comms, and other aerospace environments where reliability is paramount.
