In this paper, a direct intra-cell in-phase/quadrature (IQ) generation switched-capacitor power amplifier (SCPA) using time-domain charge redistribution is proposed. Such a direct intra-cell IQ genera...
This paper presents an ultracompact active bidirectional phase shifter (ABPS), featuring an intrinsic reciprocal phase-inverting bidirectional variable gain amplifier (PI-BVGA) core. To achieve a comp...
This paper presents a 17–32 GHz bidirectional amplitude-phase control (Bi-APC) circuit for multibeam phased-array transceivers in 40-nm CMOS. Amplitude control is achieved using a bidirectional variab...
This work proposes a hybrid active-passive variable gain block for Q-band, useful for phased-array beamforming satellite communication (SATCOM) systems and other joint communication-sensing applicatio...
This paper presents a wideband phase-invariant variable gain amplifier (VGA) adopting a gain core and matching network (MN) co-design technique. The core-MN co-design methodology expands the design sp...
This paper presents a compact and bidirectional variable gain amplifier (VGA) for compensation of interconnection losses for modular system approaches, and a version with integrated Wilkinson power di...
This paper presents an original waveguide quadruplet where dual- and single-mode cavities are combined to realize pseudo-elliptic responses while minimizing the longitudinal dimension of the filter. T...
The synthesis of duplexers without a common junction is presented. The input of the duplexers is realized on the first resonator of the TX or RX filter. The main advantage of the proposed solution is ...
This paper presents a methodology to design compact band-stop filters based on ridge waveguide lines and resonators. Such filters find application in high-power systems where isolation between high-po...
This paper presents a design of an E-plane wideband diplexer that boasts a full fractional bandwidth of about 60% with an enhanced suppression of higher order modes. The proposed design overcomes the ...
