Frequently Asked Questions
What inductance value and tolerance does the LQW18AN9N5D00D provide for RF matching network design?
The LQW18AN9N5D00D provides 9.5 nH inductance with a tight ±0.5 nH tolerance, ensuring consistent impedance matching performance across production batches in RF circuits. This precision level is critical for LC filter networks and antenna matching circuits operating above 1 GHz, where even 1 nH of deviation can shift resonant frequency by tens of MHz and degrade return loss.
How does the 650 mA current rating and 0.11 Ω DC resistance of the LQW18AN9N5D00D affect RF power amplifier designs?
With a 650 mA rated DC current and 0.11 Ω DC resistance, the LQW18AN9N5D00D introduces less than 70 mW of conduction loss at full rated current, making it suitable for RF power amplifier output matching and bias choke applications. The low DCR minimizes voltage drop in the bias supply path, preserving amplifier efficiency in 2.4 GHz and 5 GHz WLAN and Bluetooth transmitter modules.
When should an engineer select the LQW18AN9N5D00D over a multilayer chip inductor for an RF circuit above 500 MHz?
The LQW18AN9N5D00D wirewound construction achieves a Q factor of 35 at high frequency, significantly higher than typical multilayer chip inductors which degrade to Q values below 20 above 500 MHz. For resonant tank circuits, bandpass filters, and impedance transformation networks in the 0.5 GHz to 3 GHz range, the wirewound 0603 package delivers lower insertion loss and more predictable self-resonant frequency than ferrite-core alternatives.
