  1. 1. Hybrid Coupler for LMBA Input Match Using an Active Inductor

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Karthik Doddanna; [2021]
    Keywords : LMBA; gyrator-c; active inductor; hybrid coupler; TSMC 0.18um.;

    Abstract : With the increase in demand for compact and high data rate communication systems, there is a need for high efficiency with modulated signals (PAPR 5-10 dB) for base-station power amplifiers. One of the famous architectures used to achieve this is Doherty architecture. READ MORE

  3. 2. Towards Long-Range Backscatter Communication with Tunnel Diode Reflection Amplifiers

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Gustav Eriksson; [2018]
    Keywords : Amplified backscatter tag; Reflection amplifier; Battery-free; Long-range communication; Tunnel diode; Ultra-low power consumption; RFID; Frequency shift;

    Abstract : Backscatter communication enables wireless communication at a power consumption orders of magnitude lower than conventional wireless communication. Instead of generating new RF-signals backscatter communication leverages ambient signals, such as WiFi-, Bluetooth- or TV-signals, and reflects them by changing the impedance of the antenna.

  5. 4. Low noise amplifier design for dense phased arrays

    University essay from Institutionen för teknik och byggd miljö

    Author : Afzal Mohammad; [2008]
    Keywords : ;

    Abstract : Radio Astronomers demand for highly sensitive astronomical facility. Their demand is a radio telescope that can detect the weakest and deepest radio signal. To fulfill the demand of high sensitive telescope, an entirely new way of realizing a radio telescope is required. READ MORE

  6. 5. Modeling of RF-design at board level for Assisted Global Positioning System (AGPS)

    University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Author : Michael Paszowski; [2007]
    Keywords : ;

    Abstract : This thesis describes the design of a 1575.42 MHz Low-Noise Amplifier (LNA) using a Hetero-Junction Field Effect Transistor (HJ-FET) from NEC. The LNA design focuses on a minimum noise figure and good power gain in order to improve receiver sensitivity. READ MORE
