LC Band Pass Filters
Lumped-element (LC) bandpass ﬁlters range in frequency from 10 kHz to 2500 MHz, and are based on LC tank circuits consisting of parallel or series inductors and capacitors. They are relatively small and are optimized to achieve peak performance within a given set of speciﬁcations and mechanical requirements. AEI LC ﬁlters are designed to achieve very high Q, low insertion loss, and high selectivity. Standard responses include Chebyshev, Butterworth, elliptic, and Bessel and special ﬁlter shapes are available as well. They range in length from 0.5 inch to more than 10 inches, depending on the frequency, power requirements, and performance. Packaging options include surface mount, connectorized, printed circuit board mount, and drop-in. We offer Custom LC bandpass filters including custom mechanical conﬁgurations, and special requirements, such as group delay variation, amplitude matching, phase matching, and tracking can be speciﬁed.
