This paper proposes a novel concurrent dual-band receiver architecture that uses only one
six-port correlator circuit to downconvert two signals in two different bands concurrently. The …

A distinct usage of the conventional multiport architecture is introduced in this work to
explore the compendious scheme of a concurrent dual-band interferometric receiver. Dual …

A new circuit architecture for a direct-carrier six-port modulator is proposed. The proposed
architecture uses parallel binary-valued baseband signals to control binary-valued …

This paper intends to answer the question how to achieve wireless data rates that can catch
up with current Internet speed, from a basic physics point of view. It is shown that the …

This article proposes and presents an innovative approach to realizing the concurrent dual-
band transmission with only a single front-end and local oscillator at radio frequency (RF) …

The use of Schottky diodes as high-speed variable impedance loads in six-port modulators
are proposed and analyzed in this paper. The impedance dependency of diode parameters …

In this letter, a six-port transceiver for frequency-division duplex (FDD) systems is proposed
and experimentally demonstrated. The proposed transceiver that consists of a single six-port …

If present, nonlinear effects in a six-port modulator cause distortion and degradation of the
quality of the modulated output waveform. How nonlinear effects occur and their impact on …

A quadrature up-conversion mixer for low-power wireless communication systems is
presented. The circuit is based on a six-port junction with reflective loads to modulate a …

Targeting the differential RF/microwave circuit design methodology for improved broadband
wireless data transmission, a novel differential 7.5 GHz six-port modulator and demodulator …
