An Extremely Miniaturized Microstrip Bandpass Filter

A novel miniaturized UHF bandpass filter, using diagonally end-shorted coupled lines and lumped capacitors, is proposed. The new filter is not only as short as a few degrees in size, but also shows a wider stop band. A two-stage bandpass filter of this...
High performance bandpass filters, with miniaturized size, narrow bandwidth, wide stop band and low cost, are required in modern wireless communication systems, especially in mobile and portable Internet systems. Planar reduced-size filters, such as λ/2 hairpin resonator1 and slow-wave resonator 2 filters have already been published. These filters have...

Design Issues for a Solid-state Power Amplifier Integrated with a Planar Antenna

This article presents design and analysis related issues for a solid-state power amplifier (SSPA) integrated with a planar antenna. It discusses the suitability of different planar antenna structures to minimize EM interaction between the radiator and ...
Efficiency, output power and compactness are the most important parameters of a system for RF/microwave transmitter applications. The power amplifier consumes most of the DC power in a transponder. Thus, much attention is required to maximize the efficiency of the power amplifier. A high efficiency power amplifier allows compact...
