The last decade has witnessed an increasing number of wireless standards for civil, military,
and space communications. Along with the advances in integrated circuit (IC) technologies …

In this paper, a generalized analysis and design methodology of a dual-band branch-line
coupler (BLC) is presented. The proposed design, although based on the prevalent method …

In this letter, a novel wideband 3-dB Wilkinson power divider (WPD) is presented. It employs
port matching using coupled lines to achieve wider isolation bandwidth, without modifying …

A novel and very simple scheme to mend conventional dual-band impedance matching
networks is presented. It involves the employment of a load-modifying element (load-healer) …

In this paper, enhanced designs of port-extended branch-line coupler (BLC) are presented.
Initially, the analysis of the conventional dual-band port-extended equal-division BLC is …

A novel dual-band 3-dB Wilkinson power divider (WPD) is presented that requires only
partial port extension. The design methodology is based on the impedance matching …

This paper presents a dual-band impedance transformer for real source and load
impedances that is capable of providing matching at two arbitrary frequencies. There are two …

This paper presents the design and implementation of a dual-band low noise amplifier
(DBLNA) operating at 1.1 GHz and 2.4 GHz. The DBLNA employs a second-order dual-band …

A novel and simple technique to match Frequency Dependent Complex Loads (FDCLs) to
real source impedance at any two arbitrary frequencies is presented. The proposed structure …

A novel scheme is presented to realize a matching network working at two arbitrary
frequencies. The load is assumed to be complex as well as frequency dependent whereas …
