FEATURES
• Compact and lightweight, these high-performance three-pole
dielectric bandpass filters for reception, that are no larger than
two-pole sized products, exhibit excellent spurious characteris-
tics.
• It incorporates TDK’s unique microwave dielectric ceramic which
provides a high dielectric constant, low dielectric loss in micro-
wave band, and excellent
• These products are provided in tape packaging for automatic
