1. 1. Integrated antenna switch for NB-IoT

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Fredrik Zetterblom; Yunus Dawji; [2018]
   Keywords : T R Transmit Receive switch; RF switch; integrated RF switch; Narrowband Internet of Things NB-IoT ; CMOS; frontend; Technology and Engineering;

   Abstract : Transistors are used in all digital devices today. The demand of faster and smaller devices such as mobile telephones and computers constantly drives the develop- ment of smaller transistor technologies. Transistors can also be used in analog applications. Today there are commercial chips with both radio and digital sys- tems in the same package. READ MORE

3. 2. Design of GaAs MMIC passive WaveProbes

   University essay from Avdelningen för elektronik, matematik och naturvetenskap

   Author : Rameshwor Prasad Shah; [2011]
   Keywords : MTEL elektronikk; Radiosystemer;

   Abstract : GaAs MMIC are taking big space in the wireless communication in today’s world. The devices are to be characterized for higher frequencies. External passive waveprobes are used to characterize the devices. As the use and technology is increasing there will be more development on MMICs. READ MORE

4. 3.  Evaluation of broadband MMIC oscillators with external tank

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Anette Brandt; [2010]
   Keywords : ;

   Abstract : This thesis evaluates broadband Voltage Controlled Oscillators, VCO´s, using different VCO topologies and external tanks. The work has been done at Sivers IMA AB within the "INTOSC" project in the framework of the VINNEX Centre "GHZ CENTRE". Different VCO topologies are investigated and their performance is compared and evaluated. READ MORE

5. 4. A MMIC GaAs up-converter from 350 MHz to 1835 MHz realized both in a HBT diode-mixer topology and pHEMT resistive FET-mixer topology

   University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

   Author : Anders Andersson; Joakim Östh; [2006]
   Keywords : ;

   Abstract : Two mixers for up-conversion from an IF frequency of 350 MHz to a RF frequency of 1835 MHz have been designed and simulated to be used in Ericsson.s radio link system MINI-LINK. One mixer uses diodes in a balanced structure, and the other one use resistive FET-mixers, also in a balanced structure. READ MORE

6. 5. Design of a MMIC serial to parallel converter in Gallium Arsenide.

   University essay from Institutionen för systemteknik

   Author : Tony Nilsson; Carl Samuelsson; [2001]
   Keywords : Electronics; DCFL; MMIC; GaAs; serial to parallel converter; TTD; true-time delay; pHemt; Elektronik;

   Abstract : A 5-bit MMIC serial to parallel converter has been designed in Gallium Arsenide. It is intended to be used together with a 5-bit True Time Delay (TTD) circuit, but it can easily be expanded into an arbitrary number of bits. The circuit has been designed with a logic style called DCFL and a 0. READ MORE
