Two new series of small and high-power thin-film band-pass filters

Kyocera AVX has released two new series of compact, thin-film band-pass filters engineered to provide excellent RF performance in a wide range of high-power applications with crowded PCBs.

Designed to fulfil cross-market customer demand for small, high-power band-pass filters, the new series band-pass filters employ the company’s proven, multilayer integrated thin-film (ITF) technology to deliver highly repeatable and reliable RF performance with low insertion loss, steep attenuation, sharp roll-off, low-noise, and high-temperature stability. Both series also allow the quick and easy adjustment of RF parameters and feature ruggedly constructed compact, low-profile cases equipped with lead-free, solder-coated-nickel LGA terminations and compatible with automated assembly processes, including reflow, wave, and vapour phase soldering.

The new series of filters exhibit 8W continuous power handling and 50-Ohm characteristic impedance, are rated for operating temperatures extending from -40C to +85C, and support various frequency bands extending from 240-6,100MHz to satisfy the wide-ranging demands of high-frequency wireless systems in the telecommunications, defence, aerospace, medical, and consumer electronics industries. Ideal applications for the two series include mobile communications devices, such as defence and handheld radios; automatic vehicle locating (AVL), emergency services, and radar systems; and wireless LANs and test equipment.

The BP1206 Series Thin-Film Band-Pass Filters feature a miniature 1206 case that measures 3.1±0.1mm x 1.6±0.1mm x 0.6±0.3mm (L x W x H), support frequencies extending from 1,250-6,100MHz with excellent in-band performance, and exhibit out-of-band rejection values spanning -25dB to -40dB. Ideal applications exclusive to the series include 5G and 6G LTE networks, base stations, antenna matching, and satellite communications.

The BP2816 Series Thin-Film Band-Pass Filters feature a compact 2816 case that measures 7.2±0.3mm x 4.2±0.2mm x a maximum of 1.2mm (L x W x H) and support frequencies extending from 240-1,260MHz. They also display excellent in-band performance and out-of-band rejection values extending from -20dB to -45dB. Ideal applications exclusive to the series include MRI machines.

“We’re very pleased to launch the new BP1206 and BP2816 Series Thin-Film Band-Pass Filters,” said Amir Kopelman, technical services manager, Kyocera AVX. “These new high-power band-pass filters leverage our proven integrated thin-film technology and high-accuracy filter processing methods to deliver highly repeatable and reliable RF performance engineered to meet the demands of high-frequency wireless applications extending throughout the telecommunications, military, aerospace, medical, and consumer electronics industries in ruggedized cases that are smaller and lower profile than competing technologies can achieve, which enables critical design flexibility in crowded PCBs.”

The new BP1206 and BP2816 Series Thin-Film Band-Pass Filters are produced in ISO-9001 facilities and 100% tested for electrical parameters and visual and mechanical characteristics. They exhibit high lot-to-lot and part-to-part repeatability, and each production lot is evaluated on a sample basis for static humidity (85C and 85% relative humidity for 160 hours) and endurance (125C for four hours). They are also RoHS compliant and certified to IATF 16949 and shipped on tape and reel packaging.
