RF components for wireless broadcasting

Flexible, compact, and high quality RF components and protection diodes for wireless broadcasting applications

Overview

Wireless broadcasting is a key application of wireless technology, utilizing radio frequency (RF) signals in the VHF (30-300 MHz), UHF (300-3000 MHz), L-band (1-2 GHz), S-band (2-4 GHz), and Ku-band (12-18 GHz) frequency ranges to transmit audio and video content targetting a wide audience. In various system applications, such as digital audio broadcasting (DAB), FM radio, SDARS, HD radio, and TV reception, wireless technology plays a crucial role in enabling the reliable and efficient transmission of content. Infineon's RF components, including broadband LNAs, RF switches and ESD protection diodes, can significantly improve the RF Front end performance, enabling wider reach. Additionally, wireless broadcasting is used in a broad range of market applications, including wireless headphones, car radios, portable radios, TVs, set-top boxes, and satellite radios.

Infineon's RF components for digital audio broadcasting (DAB)

DAB is a popular broadcasting standard that enhances the infotainment experience in cars and homes. DAB operates in the VHF band (47 MHz to 240 MHz) and the L band (1452 MHz to 1492 MHz). This enables high-quality digital audio broadcasting with improved sound fidelity and resistance to interference. To support the growing demand for DAB, Infineon offers a range of high-performance NPN RF bipolar transistors that provide reliable and efficient performance. Our RF components offer high gain, low noise, and high linearity, making them ideal for use in DAB receivers and transmitters.

Tackle the antenna problem with devices for FM radio

FM (frequency modulation) radio is an established and widely available broadcasting technology. FM-radio-enabled active antennas are commonly found in a variety of devices, including mobile phones, PDAs, portable FM radios, and other consumer electronics. There is a clear market trend towards using FM radio without a headset cable, which requires the antenna to be integrated into the device. However, space constraints on the antenna design lead to shrinking antennas, which in turn induce high losses into the system and lower the receiver's sensitivity.

A low-noise amplifier (LNA) for FM radio applications offers a solution to the antenna challenge. By providing better impedance matching between the FM antenna and the FM receiver, the LNA solves the problem of the short FM antenna in mobile phones. As a result, the system signal-to-noise ratio is maintained at a level comparable to that achieved with a headset.

Infineon's RF components for Satellite Digital Audio Radio Service 

SDARS is a digitally encoded satellite radio broadcasting service operating in the S-band (2320-2345 MHz), delivering over 200 channels of MP3-quality or HD digital radio to paying subscribers. Infineon offers low noise NPN RF bipolar transistors in SiGe:C technology for SDARS active antenna systems, providing exceptionally low noise figure, high gain, and high linearity at minimal power consumption. These transistors are ideal for use in a variety of market applications, including automotive infotainment systems, marine and aviation systems, and consumer portable and handheld radios.
