What are the key features of LQW18AN20NG00D?
- 20 nH inductance at ±2% tight tolerance ensures repeatable RF filter and impedance matching performance across production batches
- High Q factor of 40 minimizes insertion loss in GHz-frequency LC networks and antenna matching circuits
- 550 mA DC current rating and 0.16 Ω DCR support bias choke applications in RF power amplifier stages
- Compact 0603 (1608 metric) wire-wound chip form factor enables dense placement near RF ICs and antenna feed points
What is LQW18AN20NG00D used for?
The LQW18AN20NG00D targets RF front-end impedance matching and bias choke circuits in Bluetooth, Wi-Fi 802.11, Zigbee, and sub-GHz wireless modules where a 20 nH inductance is needed in the 1 GHz to 6 GHz frequency range. Its 550 mA current rating makes it suitable for RF power amplifier bias lines where DC supply current must pass through the inductor while RF signals are blocked. The compact 0603 package and high Q factor of 40 also suit LC bandpass filter designs in NFC and UHF RFID reader front ends.

Frequently Asked Questions
What inductance and DC current rating does the LQW18AN20NG00D offer for RF bias choke designs?
The LQW18AN20NG00D provides 20 nH (0.02 µH) inductance with ±2% tolerance and a 550 mA maximum DC current rating. The low DC resistance of 0.16 Ω results in only 48 mW power dissipation at full 550 mA bias, making it an efficient RF choke for power amplifier supply lines while presenting high impedance at GHz frequencies to block RF from entering the DC supply.
At which frequency bands does the 20 nH LQW18AN20NG00D inductance provide effective RF filtering?
A 20 nH inductor presents approximately 125 Ω of reactance at 1 GHz and 376 Ω at 3 GHz, making the LQW18AN20NG00D effective as a series choke or LC filter element in the 1 GHz to 6 GHz frequency range. This covers 2.4 GHz Bluetooth and Wi-Fi, 5 GHz Wi-Fi 802.11ac/ax, and UWB bands near 3.5 GHz and 6.5 GHz used in precision ranging and radar applications.
How does the LQW18AN20NG00D's Q factor of 40 compare to multilayer inductor alternatives?
Wire-wound inductors like the LQW18AN20NG00D typically achieve Q factors of 35 to 50 at GHz frequencies compared to 15 to 25 for equivalent multilayer chip inductors. The higher Q factor of 40 directly reduces insertion loss in bandpass filter designs by 0.5 dB to 1 dB compared to a multilayer 20 nH alternative, which is significant for sensitivity-limited RF receiver front ends operating at -100 dBm signal levels.
What PCB footprint does the 0603 package of LQW18AN20NG00D require compared to a 0402 alternative?
The 0603 (1608 metric) package of the LQW18AN20NG00D occupies a 1.6 mm x 0.8 mm land pattern with a total footprint of approximately 1.28 mm². This is 2.5 times the footprint of a 0402 (1005 metric) alternative at 0.5 mm², but the 0603 wire-wound construction supports the higher 550 mA current rating and Q factor of 40 that most 0402 multilayer inductors cannot achieve at 20 nH.
