This paper describes X-Band power amplifier (PA), low noise amplifier (LNA) and switches that can be used in transmit/ receive modules which are developed with GaN technology. For Transmit chain two 25 W high power amplifiers that are tuned between 8-10 GHz and 10-12 GHz bands are designed. A low noise amplifier with 2 W survivability and less than 2dB noise figure is designed for receive chain. Furthermore, an RF switch that is capable of withstanding 25 W RF power is developed for the selection of transmit or receive chains. Measurement results show that both power amplifiers produce 25 W of power. Low noise amplifier has more than 20 dB small signal gain with less than 2 dB noise figure. RF switch has 50 dB of isolation with less than 1 dB insertion loss.

Design and implementation of a voltage source converter based statcom for reactive power compensation and harmonic filtering Çetin, Alper; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2007) In this thesis, design and implementation of a distribution-type, voltage source converter (VSC) based static synchronous compensator (D-STATCOM) having the simplest converter and coupling transformer topologies have been carried out. The VSC STATCOM is composed of a +/- 750 kVAr full-bridge VSC employing selective harmonic elimination technique, a low-pass input filter, and a /Y connected coupling transformer for connection to medium voltage bus. The power stage of VSC based STATCOM is composed of water-co...
A Self-Powered and Efficient Rectifier for Electromagnetic Energy Harvesters Ulusan, Hasan; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2014-11-05) This paper presents an interface circuit for efficient rectification of voltages from electromagnetic (EM) energy harvesters operating with very low vibration frequencies. The interface utilizes a dual-rail AC/DC doubler which benefits from the full cycle of the input AC voltage, and minimizes the forward bias voltage drop with an active diode structure. The active diodes are powered through an AC/DC quadrupler with diode connected (passive) transistors. The interface system has been validated to drive 22 m...
Highly Integrated 3 V Supply Electronics for Electromagnetic Energy Harvesters With Minimum 0.4 V-peak Input Ulusan, Hasan; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2017-07-01) This paper presents a self-powered interface enabling battery-like operation with a regulated 3 V output from ac signals as low as 0.4 V-peak, generated by electromagnetic energy harvesters under low frequency vibrations. As the first stage of the 180 nm standard CMOS circuit, harvested signal is rectified through an ac/dc doubler with active diodes powered internally by a passive ac/dc quadrupler. The voltage is boosted in the second stage through a low voltage charge pump stimulated by an on-chip ring osc...
Joint Mitigation of IQ Imbalance and Power Amplifier Impairments by Real Valued Time Delay Neural Networks Yeşil, Soner; Gürtunca, Burak; Yılmaz, Ali Özgür (2019-08-22) This paper represents a neural network based joint mitigation of the IQ imbalance and power amplifier nonlinearities that cause degradation in the transmit signal quality of the wireless communication systems. A Real Valued Time Delay Neural Network architecture for this purpose has been verified on a hardware including cascaded NXP-MD8IC925 and NXPBLF8G10LS power amplifier components performing a total of 46dB gain. The test setup has been controlled over MATLAB in order to have a closed loop adaptive digi...
ADAPTIVE CONTROL OF POWER AMPLIFIER LINEARIZATION TECHNIQUES BY USING HYBRID ANALOG AND DIGITAL APPROACHES Abdulwahab, Bassam; Tayfun, Nesimoglu; Electrical and Electronics Engineering (2021-9) Power Amplifiers (PA) are widely used in mobile communication systems, yet power amplifiers have a non-linear region which is the major problem in all communication and radar systems. Moreover, PAs show a low power efficiency when operating in their linear region and are highly non-linear when operating in their high-efficiency region. To overcome such issues, there are different methods to linearize PAs and other methods to enhance their power efficiency. These linearization methods are built to meet a cer...
