Frequently Asked Questions
What RF frequency range is the LQW18AN36NJ00D with 0.036 µH inductance best suited for in bandpass filter designs?
The 0.036 µH (36 nH) inductance presents approximately 113 Ω reactance at 500 MHz and 452 Ω at 2 GHz, making it most useful in LC bandpass filter designs targeting the 500 MHz to 2.5 GHz range. This covers major wireless bands including 868 MHz and 915 MHz sub-GHz ISM, 2.4 GHz Bluetooth and Zigbee, and cellular LTE low-band frequencies, where the Q factor of 40 ensures low filter insertion loss.
How does the 400 mA current rating and 0.26 Ω DC resistance of LQW18AN36NJ00D affect its use as an RF choke in a PA bias network?
At 400 mA maximum DC current, the LQW18AN36NJ00D drops approximately 104 mV across its 0.26 Ω DC resistance, which is acceptable in most PA bias feeds operating from 3.3 V or 5 V supply rails. The inductor's reactance at RF frequencies ensures that the PA drain or collector sees a high-impedance RF block while the DC bias passes freely, with the resistive loss in the choke remaining below 42 mW at full rated current.
For a Bluetooth 2.4 GHz antenna matching network, what advantage does the Q factor of 40 provide in the LQW18AN36NJ00D?
A Q factor of 40 at 2.4 GHz means the inductor's resistive loss is 1/40th of its reactive impedance, contributing minimal dissipation in the antenna matching network. This preserves radiated power efficiency and avoids signal degradation in the match, which is important for Bluetooth modules where transmit power is limited to 0 dBm to 10 dBm and every 0.5 dB of matching network loss directly reduces effective radiated power and link budget margin.
How does the ±5% tolerance of LQW18AN36NJ00D compare to absolute-tolerance inductors for narrow-band sub-GHz filter designs?
The ±5% tolerance on 0.036 µH means the actual inductance can range from 0.0342 µH to 0.0378 µH, a spread of 3.6 nH. In a narrow-band 915 MHz filter designed for a 26 MHz bandwidth, this inductance spread can shift the center frequency by approximately ±2.5%, potentially moving the filter edge by 23 MHz and reducing rejection margin at the band edge. Designers targeting tighter filter specifications should evaluate whether absolute-tolerance variants or post-assembly tuning are required.
