Abracon AFII-LC-0x Band Pass Filters
Abracon AFII-LC-0x Band Pass Filters are designed using advanced Low-Temperature Co-fired Ceramic (LTCC) technology. These filters are crucial for ensuring that only a specific frequency band passes through while rejecting interference from adjacent bands. The AFII-LC-0x band-pass filters are compact and available with typical center frequencies of 1400MHz, 2450MHz, 7000MHz, and 7245MHz. These filters feature single-ended input and output, low insertion loss, high-quality performance, and excellent selectivity with high out-of-band rejection. The AFII-LC-0x band-pass filters are mainly used in home automation, secure car access, indoor navigation, hands-free payment, smart access, and object detection. The AFII-LC-0049-Q band-pass filter is AEC-Q200 qualified and suitable for automotive UWB applications.
