Low-Loss Matching Network Design for Band-Switchable Multi-Band Power Amplifier
This paper presents a novel design scheme for a bandswitchable multi-band power amplifier (BS-MPA). A key point of the design scheme is configuring multi-section reconfigurable matching networks (MR-MNs) optimally in terms of low loss matching in multiple frequency bands from 0.7 to 2.5 GHz. The MR-MN consists of several matching sections, each of which has a matching block connected to a trans...
متن کاملCompact Quad Band Filter for Multi Band Wireless Applications
A quadband filter for 1.57 GHz GPS, 5.2 GHz WLAN and 3.5 GHz Worldwide Interoperability Microwave Access is designed and tested in this work. A compact Defected Ground Structure (DGS) quad-band microstrip Band Pass Filter, stub loaded Low Pass Filter, short circuited uniform impedance resonator and ring resonator are used to maintain the size and performance. Use of stub resonator at central po...
متن کاملRealization of a Single-Chip, SiGe:C-Based Power Amplifier for Multi-Band WiMAX Applications
A fully-integrated Multi-Band PA using 0.25 μm SiGe:C process with an output power of above 25 dBm is presented. The behaviour of the amplifier has been optimized for multi-band operation covering, 2.4 GHz, 3.6 GHz and 5.4 GHz (UWB-WiMAX) frequency bands for higher 1-dB compression point and efficiency. Multi-band operation is achieved using multi-stage topology. Parasitic components of active ...
متن کاملCo-Design of Multi-Band High-Efficiency Power Amplifier and Three-Pole High-Q Tunable Filter
This letter reports a novel methodology for co-design of broadband power amplifiers (PAs) and hightunable filters. It is for the first time demonstrated that the tunable filter’s input port can be synthesized to directly match the transistor’s output, thus eliminating the conventional broadband/band-reconfigurable matching network of the PA. This leads to minimized circuit size, volume, and los...
