Standard BPF for Ham Radio User
Amateur radio frequency allocation is done by national telecommunication authorities and oversees by the International Telecommunication Union (ITU). Individual amateur stations are free to use any frequency within authorized frequency ranges. The authorized bands may vary by the class of the station license.
Frequencies above 30 MHz are referred to as Very High Frequency (VHF) region and those above 300 MHz are called Ultra High Frequency (UHF). The allocated bands for amateurs are many megahertz wide, allowing for high-fidelity audio transmission modes (FM) and very fast data transmission modes.
VHF and UHF amateur radio frequency allocation:
6 meters amateur radio band: 50 MHz - 54 MHz
4 meters amateur radio band: 70 MHz - 70.5 MHz
2 meters amateur radio band: 144 MHz - 148 MHz
1.25 meters amateur radio band: 219 MHz - 220 MHz (Canada only), 222 MHz - 225 MHz (US & Canada)
70 centimeters amateur radio band: 420 MHz - 450 MHz
33 centimeters amateur radio band: 902 MHz - 928 MHz
23 centimeters amateur radio band: 1240 MHz - 1300 MHz
13 centimeters amateur radio band: 2300 MHz - 2310 MHz (lower segment), 2390 MHz - 2450 MHz (upper segment)
Temwell designs, manufactures and markets RF & Microwave solution for a wide variety of applications. We special released standard VHF and UHF band pass filters to meet amateur radio, self-training, DIY and hobbyist needs. The helical band pass filters have excellent noise interference suppression which can eliminate noise and do not affect the quality of communication. Our existing amateur radio bands included 146 MHz, 232.5 MHz, 435 MHz, 915 MHz, 1270 MHz, 1282.5 MHz, etc. Each frequency we offer at least 3 different specifications for you to choose. All models are available from stock. Welcome to visit our Shopline Store to check and take your prefer filter.
We are also desired to build new standard series for Ham radio user in European area, Australia area, South Africa area, South America area, etc. Welcome to contact us for more detail discussion.
