Do you know how important RF filters are? With the advent of 5G, the number of frequency bands used will be double.

When the WIFI transmission system is converted from an indoor regional environment to large-scale outdoor signal transmission, it is inevitable that the signals will interfere with each other, especially for the mainstream 5G transmission signals outdoors. When WIFI transmission enters applications such as smart factories, smart warehousing, and smart seaports, the original 5G signal will be severely affected, and WIFI and 5G signals will interact from time to time.

However, the powerful application of WIFI has become an indispensable design method for various new-generation applications. Therefore, in major regions such as the United States and Europe, special block divisions are made to deal with the interference problem in this part. Then RF saw baw filter will be a very important role in the progress.

In Temwell, Our RF saw baw filter development engineers will consider not only the communication performance but also the configuration of the corresponding RF Filter components when developing products or systems. RF saw and baw filters design will play an important role in the new generation of communication design as an important assistant for coordinating WIFI 6 and 5G signals. If you have any problems with RF Filter Microwave Components, welcome to contact us now.

A Satellite network is the operation of various wireless communications through communication satellites in the earth's orbit. Common applications are in television, telephone, broadcasting, Internet, and military fields, including satellite observation, satellite telephone, satellite positioning system, satellite mobile communications, etc. A Communications Satellite, called CS, is a satellite that transmits and amplifies radio communication signals through a repeater. Through the communications satellite, a communication channel can be established between a transmitter station on the ground and a remote receiving station all over the world.

How Can We Do to Prevent the Interference from Occurring?

The engineer can use band stop filters with 2 suitable methods to prevent or resolve it.

1: Before the signal is transmitted, use a customized constant k band pass filter are including constant k low pass filter, constant k high pass filter, and constant k band stop filter to filter the signal in advance to ensure the quality of the signal.
2: At the receiving end, after the noise is filtered by customized constant k type filters are including ku band filter and ka band filter, the received signal is processed to improve the efficiency of signal processing.

Temwell is the professional custom RF bandpass filter to offer band reject filters and constant k filters for Satellite Network Applicated in broadcasting, communication, disaster rescue, tracking, emergency & safety, maritime affairs and etc to prevent the conflict that occurs and efficiency of signal processing.

Today’s car is no longer the same as half a century ago that is just a transmission device driven by an internal combustion engine. After years of development, these advanced electronic systems are equipped with a dedicated microprocessor for computing. So that the car can make the best, most suitable, and most efficient operation.

Here are a few common applications:
1. Smart key
Installing the key with a wireless communication device allows the driver to unlock, lock and start the vehicle more easily and simply through the key, which can greatly improve the ability of remote control of the vehicle while meeting safety.

2. Autonomous driving
An important milestone in the development of automotive electronics is to use powerful computer systems, sensor arrays, networks, and satellite positioning systems to realize auto-driving cars. Under highly demanding safety conditions, auto-driving cars can be realized to complete tasks. This can only be achieved by relying on powerful electronic equipment.

3. Advanced Driver Assistance Systems ( ADAS )
Advanced Driver Assistance Systems (ADAS) is the system that assists the driver in-car driving control. The main function is not to control the car, but to provide the driver with information on the working conditions of the car and changes in the driving environment outside the car. In some cases, it can assist in controlling the car, but the driver is still the protagonist in controlling the car. The auxiliary system is only a supporting role for warning, prompting, and assisting the driver, allowing the driver to take early measures to avoid traffic accidents.

4. Breaking Electrical Assist System (BEAS)
In addition to the driving assistance system, the electronic brake assist system as Breaking Electrical Assist System (BEAS) is also a very important car safety system, including Anti-lock Brake System (ABS), Brake Assist System (BAS), Traction Control System (TCS), Electronic Brake-force Distribution (EBD), Electronic Brake-force Distribution (EBD), Brake Override System (BOS) and Electric Parking Brake (EPB).

Radio frequency filters are a kind of electronic component which is usually utilized to allow particular signals or frequencies to pass and at the same time eliminate unwanted signals and noises (interference). In other words, an RF filter is designed to attenuate or transmit certain signals and frequencies. Radio frequency filters help to cut out RF interference or noisy signals that could occur to your devices, equipment, instruments, or systems.

The RF filters are designed in a way that could easily operate on frequency ranges that range from low to medium to extremely high frequency. It is most frequently used in equipment such as wireless communications, broadcast radio, television, 5G applications and etc.

In Temwell, we provide 4 basic types of Radio Frequency Filters that can be used in combination with various electronics, including RF Band Pass Filters, RF Band Stop Filters, RF Low Pass Filters, RF High Pass Filters.
