HF Pas Band Filter

HF Pass Band Filter

HF Pass Band Filter has a certain degree of isolation between the output ports. The main technical parameters of power divider include power loss (including insertion loss, distribution loss and reflection loss), VSWR of each port, isolation between power distribution ports, power capacity and bandwidth, etc.

In the field of communication, frequency band refers to the frequency range of electromagnetic wave, in Hz. According to the frequency, it can be divided into:

1. Very low frequency (VLF) 3 kHz ~ 30 kHz, corresponding to the wavelength of very long wave 100 km ~ 10 km.

2. The low frequency (LF) is 30 kHz ~ 300 kHz, and the wavelength of the corresponding electromagnetic wave is 10 km ~ 1 km of the long wave.

3. The intermediate frequency (MF) is 300 kHz ~ 3000 kHz, and the wavelength of the corresponding electromagnetic wave is 1000 m ~ 100 m.

4. The high frequency (HF) is 3 MHz ~ 30 MHz, and the wavelength of the corresponding electromagnetic wave is short wave 100 m ~ 10 m.

5. Very high frequency (VHF) is 30 MHz ~ 300 MHz, and the wavelength of the corresponding electromagnetic wave is 10 m ~ 1 m.

6. Ultra high frequency (UHF) 300 MHz ~ 3000 MHz, and the wavelength of the corresponding electromagnetic wave is decimeter wave 100cm ~ 10cm.

7. Ultra high frequency (SHF) is 3 GHz ~ 30 GHz, and the wavelength of the corresponding electromagnetic wave is 10 cm ~ 1 cm.

8. Extremely high frequency (EHF) is 30 GHz ~ 300 GHz, and the wavelength of the corresponding electromagnetic wave is 10 mm ~ 1 mm.

9. To high frequency 300 GHz ~ 3000 GHz, the wavelength of the corresponding electromagnetic wave is 1 mm ~ 0.1 mm.

In order to make rational use of spectrum resources and ensure that various industries and services will not interfere with each other when using spectrum resources, the Radio Commission of the International Telecommunication Union (ITU-R) has promulgated International Radio rules, which stipulate a unified frequency range for the wireless frequency bands used by various services and communication systems.

According to the international radio regulations, the existing radio communication is divided into more than 50 different services, such as aviation communication, navigation communication, land communication, satellite communication, radio, television, radio navigation, positioning, telemetry, remote control and space exploration, and a certain frequency band is specified for each service.
