Ham Radio Filter with Flexible Bandwidth
Passband bandwidth is the difference between the upper and lower cutoff frequencies. For example, a bandpass filter, a communication channel, or a signal spectrum. It is typically measured in hertz. A key characteristic of bandwidth is that any band of a given width can carry the same amount of information, regardless of where that band is located in the frequency spectrum. Bandwidth is a key concept in many radio communications applications. In radio communications, bandwidth is the frequency range occupied by a modulated carrier signal.
Amateur radio faces lots of signal interference affected communication. The interference may prevent reception altogether, may cause only a temporary loss of a signal, or may affect the quality of the sound or picture produced by your equipment. Use a higher bandwidth filter will make more suitable for amateur radio application.
Temwell helical band pass filter is a device that passes frequencies within a certain range and rejects frequencies outside that range. We provide various different bandwidth band pass filters for 6 standard amateur radio frequencies to protect their working frequency bands. The 6 standard amateur radio frequencies are 146 MHz, 232.5 MHz, 435 MHz, 915 MHz, 1270 MHz and 1282.5 MHz. The bandwidth included 5 MHz, 10 MHz, 20 MHz, 30 MHz, 50 MHz, 60 MHz, 70 MHz, 80 MHz, 120 MHz, 200 MHz, etc. Along with stable transmission of data, the higher bandwidth also has better anti-jamming capabilities. It can effectively protect signals from being interfered. You only need to use one λ/4-wave helical band pass filter to achieve high bandwidth. And the volume is not very large. Temwell helical band pass filter can reduce time and cost when designing.
