Engineered for broadband bias and decoupling networks, the HALT30012 conical inductor delivers continuous resonance-free choking from 100 MHz through 40 GHz and beyond. Its air-core tapered cone winding distributes parasitic capacitance along a mechanical gradient, eliminating the narrowband self-resonance notches that plague conventional solenoid chokes.
Where a standard wirewound inductor self-resonates and turns capacitive, the HALT30012 maintains a flat, inductive high-impedance profile across the entire 0.1-40.0 GHz rated span, verified on a TRL-calibrated VNA with microstrip fixturing. The self-resonant frequency exceeds 40.0 GHz, so the choke never becomes a high-pass filter inside your signal path. Each production batch ships with measured .s2p Touchstone data (10 MHz-40 GHz) for direct import into ADS, HFSS or AWR.
As a manufacturer of custom conical inductors, we tailor every parameter to your design. Customization options include:
Typical customization cycle: engineering review within 24 hours, prototype samples in 5-7 working days, production lots in 15-25 working days. Each custom variant is VNA-characterized and shipped with its own .s2p data file.
