RF Power

RF Power

RF Power is used in applications which use controlled electromagnetic radiation to heat items or to power all kind of processes. Würth Elektronik WE-AC HC inductors are needed in the RF Power field. These high current air core inductors are suitable for high frequency and high current applications. Typical applications may include: MRI and PA, CO2 Lasers, Industrial Heating, Welding and Drying Systems, PMR Stations, and Weather Radars.

Filters

Filters

The Würth Elektronik portfolio for filters includes low-pass and band-pass filters with sizes available in 0603, 0805 and 1008. These filters have a wide range of applications, which include Bluetooth, Wi-Fi, GSM, IoT (Internet of Things) and radio systems for cellular and wireless frequencies.

On-Board Shielding

On-Board Shielding

Würth Elektronik offers Shielding Cabinets to protect PCBs from EMI radiation. The WE-SHC series shields RF input, output and amplifier stages as well as oscillators and EMC sensitive components with plastic cases.

Balun

Balun

RF transceivers are increasingly utilizing more and more differential topologies due to the inherent benefit of noise reduction, and a balun is always needed to communicate between single ended antenna and a differential line. Würth Elektroniks RF-balun portfolio includes multilayer SMD baluns with balanced impedances of 50, 100 and 200 W in the sizes of 0603 and 0805. These baluns have applications in the frequency ranges of 2.45 and 5.5 GHz, which include wireless communication systems and IoT.

  • WE-BAL – Multilayer Chip Balun
Matching Network

Matching Network

Würth Elektronik provides expert advice to customers on how to place and impedance match the antenna on the PCB. Anything (metal, plastic, battery, LED, microphone, etc.) in close proximity to the antenna can change the input impedance of the antenna and result in an undesired response. Antenna matching is done to match the impedance of an antenna to 50 Ω in a certain frequency range.

Antenna

Antenna

Due to the nature of antennas sending and receiving electromagnetic signals, they interact and are affected by the entire surrounding environment and are extremely sensitive to electromagnetic fields. This can be extremely problematic for RF engineers when integrating into a design an antenna that is small, has good gain and efficiency in the frequency range of operation, and is able to work as desired in different PCB environments. Würth Elektronik multilayer chip antennas (WE-MCA) are the perfect solution for RF design engineers who are limited by time and cost restraints. These LTCC-based multilayer chip antennas are very small in size, easy to tune (antenna matching) and have excellent size-to-performance ratio. WE-MCA covers the frequency ranges from 433 MHz to 5.8 GHz, which include applications like home RF/smart home, WLAN, Bluetooth, GPS/GNSS, ZigBee, and cellular communication technologies. Particularly important are the 868, 915 and 2450 MHz frequencies, which are and will be extensively used in home automation.

RF Connectors
