Improved compaction of multilayer MMIC/MCM baluns using lumped element compensation

Abstract

A novel lumped impedance matched type of Marchand balun in MMIC/MCM technology is described which is compact enough even for the low-GHz frequency range. Broadband performance and balance of this component are sufficient for the use in many wireless applications. SummaryMonolithic and hybrid broadband compensated baluns of the Marchand type [l], [a] feature excellent electrical performance, but are quite space consuming Single -Ended Input and Differential -Output ca.

A novel interpretation of transistor S-parameters by poles and zeros for RF IC circuit design

“…According to (12) and the two-pole approximation, S 22 has two poles and two zeros just like the case of S 11 . The two zeros of S 22 fall between its two poles in the cases of 0.5, 1, and 2 mm.…”

Wideband Broadside-Coupled Line Baluns Enabled by Multimaterial Additive Manufacturing

“…As Z A = Z B = 50 is the most common MB implementation [28], [29], [30], [31], [32], [36], [37], [66], [67], [68], [69], [70], this manuscript will focus on its realization using inkjet printing and will aim to maximize its FBW. Its corresponding performance is illustrated in detail in Fig.…”
