Sub-1GHz Bandpass Filter
Therefore, for a long time, all kinds of wireless communication products have been designed in the sub-1GHz range. Even if the 5G standard is published, many RF products is transmitted at the 5G frequency band as carrier and still working at SUB-1GHZ band for terminal product signal transmission after frequency down-converting, such as: household electronics appliances, car communication, regional network communication, IoT transmission, M2M communication, Shipping and aviation communications, mining communications , public safety systems, etc., all of the above using shows the importance of the SUB-1GHZ frequency band.
For the deepest development experience of the SUB-1GHZ frequency band, Temwell group presents the most complete research and development team, whether it is Helical Filter, Cavity Filter and DR Filter can provide a comprehensive SUB-1GHZ frequency Design, from 45MHz to 1GHz, every point of frequency band can customize the best filter performance for you to use. Here we demonstrate more than 3000 completed specification with spec sheet online for your reference. Any online specification can be redesigned as a development template, including internal parameter changes, such as: frequency, bandwidth, attenuation value, RL, etc., as well as external dimensions, categories (Cavity, DR, Helical), Or types (Connector, SMT, Pin) etc.
Following, you could see Temwell establish bandpass Filters for Sub-1GHz design application. According to standard using frequency band and bandwidth, we show out our filter performance at fc= 783MHz, 722.5MHz, 868MHz, 928 MHz, 433MHz and 450Mhz, etc.
During these frequency band, Temwell offer not only standard BW spec., but also at least 5 different BW spec item for your RF design, ex: 5MHz, 10MHz, 15MHz, 20MHz, 30MHz, 40MHz, 60MHz, 80MHz, 100MHz, 130MHz,etc.
