WebFor RCs characterized by a lowest usable frequency (LUF) of 80 MHz ~ 200 MHz, the oscillating wall stirrer is typically used. The stirrer operates as an interior moving scatterer analogous to the traditional rotating stirrers. This innovative technique and patented design is developed by our in-house Engineering and R&D department. Web3 dec. 2024 · Figure 10. Effects of L3 Inductor, Low Frequency Response. The component choice depends on the lowest required operating frequency and the maximum current that must be supported. In terms of the lowest usable frequency, Case 1, where L3 = 1 μH, gives the best results.
