Key Features
- 3.9 nH air-core multilayer construction provides stable inductance at RF frequencies up to several GHz with minimal core saturation effects
- Tight ±0.3 nH tolerance enables precise impedance matching in RF front-end circuits such as antenna networks and LNA input matching at 2.4 GHz and 5 GHz bands
- Ultra-compact 0603 (1608 metric) package with 0.15 Ohm DC resistance minimizes PCB footprint and insertion loss in space-constrained wireless module designs
Applications
The LQG18HN3N9S00D is designed for RF impedance matching networks, low-pass filter stages, and bias chokes in Bluetooth, Wi-Fi, and other wireless communication modules operating in the 2.4 GHz and 5 GHz ISM bands. Its air-core multilayer construction eliminates core saturation effects, making it suitable for high-linearity RF signal paths where even small non-linearities would degrade receiver sensitivity or transmit EVM. Engineers also deploy it in antenna tuning circuits, balun networks, and VCO tank circuits in IoT sensor nodes and wearable wireless devices where 0603 package size and sub-nH accuracy are essential.

Frequently Asked Questions
What inductance value and tolerance does the LQG18HN3N9S00D offer for RF impedance matching?
The LQG18HN3N9S00D provides a nominal inductance of 3.9 nH with a tight tolerance of ±0.3 nH. This precision is essential for RF impedance matching networks at 2.4 GHz and 5 GHz where a shift of even 0.5 nH in an antenna match inductor can increase return loss by 2 dB to 3 dB and reduce radiated efficiency, directly impacting wireless link budget and communication range.
How does the air-core construction of the LQG18HN3N9S00D benefit high-linearity RF signal paths?
The air-core multilayer construction of the LQG18HN3N9S00D eliminates magnetic core saturation, which means inductance remains stable regardless of the RF signal amplitude, unlike ferrite-core inductors where saturation at high signal levels causes inductance droop and harmonic distortion. This linearity is critical in LNA input matching networks and PA output filters operating at signal levels from -100 dBm to +20 dBm where non-linear core effects would increase third-order intermodulation distortion beyond acceptable limits.
What DC resistance does the LQG18HN3N9S00D have, and how does it affect insertion loss in RF filter designs?
The LQG18HN3N9S00D has a DC resistance of 0.15 Ohm, which at 3.9 nH represents a Q factor typically exceeding 20 at 2.4 GHz. Low DC resistance directly reduces insertion loss in LC filter and matching network designs, keeping signal loss below 0.5 dB in a single-section low-pass filter stage, which is important for maintaining the sensitivity and output power specifications of Wi-Fi and Bluetooth transceivers in IoT and wearable products.
Is the LQG18HN3N9S00D suitable for 5 GHz Wi-Fi antenna matching, and what package should the PCB layout reserve?
Yes, the LQG18HN3N9S00D is well-suited for 5 GHz Wi-Fi antenna matching networks because its air-core 3.9 nH inductance maintains resonance accuracy in the 5.15 GHz to 5.85 GHz band without core loss degradation. The 0603 (1608 metric) package requires a PCB land pattern of approximately 1.6 mm x 0.8 mm, and a keep-out clearance of at least 0.3 mm from adjacent metal features is recommended to minimize parasitic coupling that could shift the resonant frequency of the antenna matching network by more than ±50 MHz.
