“…In this scenario, systems require much higher linearity than BBoF to transmit RF signal properly and present distance limitations when it is proposed to transmit on different wireless standards at higher RF frequencies, due to the high fiber chromatic dispersion at such frequencies [16]. Some attempts to design RAUs for RFoF have been made in recent years with promising results and performance, transmitting RF at 2.5 GHz [17,18], 5 GHz [19], or 12 GHz [20].…”

Wireless broadband access networks have been positioning themselves as a good solution for manufacturers and users of IoT (internet of things) devices, due mainly to the high data transfer rate required over terminal devices without restriction of information format. In this work, a review of two Radio over Fiber strategies is presented. Both have excellent performance and even offer the possibility to extend wireless area coverage where mobile networks do not reach or the 802.11 network presents issues. Radio Frequency over Fiber (RFoF) and intermediate Frequency over Fiber (IFoF) are two transmission strategies compatible with the required new broadband services and both play a key role in the design of the next generation integrated optical–wireless networks, such as 5G and Satcom networks, including on RAU (Remote Antenna Unit) new functionalities to improve their physical dimensions, employing a microelectronic layout over nanometric technologies.

“…These systems, however, require much higher linearity than BBoF to transmit the signal properly and they show distance limitations when transmitting several WLAN standards due to the high chromatic dispersion of the fiber at such frequencies [5]. Several attempts to design RAUs for RoF have been made in recent years with promising results and performance, transmitting RF at 2.5 GHz [6,7], 5 GHz [8], or 12 GHz [9]. However, RoF systems require high-speed circuit design and high-performance photonic devices, therefore increasing the power consumption and the overall cost of the DAS significantly.…”

This article presents an optimized design of a low-noise transimpedance amplifier (TIA) with high linearity for use in the downlink receiver of a remote antenna unit (RAU). The aim of this design is to be used in a cost-effective indoor distributed antenna system (DAS) for WLAN transmission using a mixed fiber-wireless system. The circuit topology consists of a fully differential shunt–shunt feedback TIA with digitally programmable transimpedance. An open-loop gain compensation technique is used to maintain stability and constant bandwidth (BW). The TIA has been fabricated in 65 nm CMOS technology with a 1.2 V voltage supply. The total power consumption of the TIA is 6 mW. A complete electrical and optical characterization with a 1550 nm PIN photodiode has been performed to demonstrate the reliable 54 Mb/s 802.11a WLAN transmission achieved with an error vector magnitude (EVM) lower than 3% for a 20 dB optical input range.

Heterojunction bipolar transistor (HBT) InP/InGaAs has been modelled and analyzed in this paper as an optoelectronic mixer (OEM). The HBT proposed was simulated by considering the wavelength of 1550nm for an upconversion frequency of 30GHz. This transistor was simulated by using the Apsys Crosslight software. Its characteristics was further investigated to develop the appropriate structure device for OEM application. The data such as frequency up conversion, gain and bandwidth of the HBT OEM will be presented. This proposed HBT InP/InGaAs can be potentially implemented in the broadband RoF system to perform photodetection and frequency up-conversion.
