Transceivers operating in frequency division duplex experience a transmitter leakage (TxL)
signal into the receiver due to the limited duplexer stopband isolation. This TxL signal in …

This article presents novel solutions for suppressing passive intermodulation (PIM) distortion
in frequency-division duplexing (FDD)-based radio transceivers, stemming from nonlinear …

In this article, we model and develop effective cancellation schemes for passive
intermodulation (PIM) distortion induced by external objects in the vicinity of the transmitter …

In this paper, a novel decorrelation-based concurrent digital predistortion (DPD) solution is
proposed for dual-band transmitters (TXs) employing a single wideband power amplifier …

Wideband millimeter wave and terahertz systems face severe nonlinearity and other
practical impairments such as transmitter and receiver in-phase/quadrature imbalances …

During the last decades, wireless communications have evolved from a scarce technology,
used by professionals for niche applications to a rapidly advancing research field. Ever …

This paper proposes two digital receiver (RX) linearization and in-phase/quadrature (I/Q)
correction solutions, where an additional reference RX (ref-RX) chain is adopted in order to …

In RF transceivers operating in carrier-aggregation, spurs are generated on the transceiver
chip which may down-convert any blocker signal located at the spur frequency into 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 mixed signal transmit (TX)-interference cancellation technique targeting Long Term
Evolution (LTE) carrier aggregation (CA) receivers is proposed. The introduced architecture …
