Powering High-Power RF Amplifiers: The High-Current 500mA Advantage
In high-power RF transmitters and broadband Bias Tees designed for GaAs (Gallium Arsenide) and GaN (Gallium Nitride) solid-state power amplifiers (SSPAs), typical micro-choke inductors quickly burn out or saturate due to high bias currents.
The HALT20008 solves this power bottleneck. By utilizing a uniform, low-DCR 0.08mm high-purity copper wire throughout the entire winding, it safely handles up to 500 mA of continuous DC bias current (2.5 times the current capacity of standard 40GHz chokes) with minimal heat generation.
It provides an outstanding 130 nH ± 20% inductance with a flat, resonance-free broadband response spanning from 200 MHz to 22 GHz, covering the entire X-band, Ku-band, and K-band seamlessly.

Micro-Assembly & Mounting Best Practices
To ensure the HALT20008 operates at its nominal 130nH inductance and prevents parasitic interference on your high-power PCB layout:
1.Apex (Small End) Orientation: Solder the conical apex (small head) directly to the RF transmission line trace, keeping the connecting lead as short as possible (ideally <0.5) to prevent high-frequency insertion loss spikes.
2.Epoxy Underfill Required: Because of the larger 0.08mm wire weight, the HALT20008 must be secured with a non-conductive, low-dielectric RF epoxy/glue at its base during assembly to prevent mechanical fatigue and microphonics.
3.Heat Dissipation: Ensure the base of the coil has adequate air gap or non-conductive thermal pad space if operating continuously near the 500mA thermal limit.
FAQ
Q1: Can I run more than 500mA through the HALT20008 intermittently?
A: The 500mA rating is for safe continuous DC operation at +125℃ ambient. Running higher currents can increase the coil's internal temperature and DCR, possibly degrading performance. For higher current needs, contact Vibratac for custom wire-gauge conical coils.
Q2: Does Vibratac provide step models (.stp) for mechanical space planning?
A: Yes. We provide full 3D STEP models and High-Frequency S-parameter simulation data (.s2p) from 10MHz to 22GHz to ensure hassle-free CAD integration and RF circuit design.
Q3: What are the storage requirements to prevent lead tarnish?
A: The HALT20008 is shipped in standard anti-static waffle packs. Keep them stored at 20–25℃ and 40%–60% RH. The recommended shelf life is 1 year under standard storage conditions.
