Add  Characterization of systematic and random diode mismatches in antiparallel-diode mixers
Authors: Gutta, Venkata | Parker, Anthony Edward | Fattorini, Anthony
Date: 2009
Subject Keyword: 090600 Electrical and Electronic Engineering | microwave mixers | millimeter-wave mixers
Language: eng
Resource Type: journal article
Identifier: http://hdl.handle.net/1959.14/85333
Description: Diode mismatch in an antiparallel-diode (APD) mixer results in an unwanted virtual local-oscillator (LO) leakage. At a radio system level, the virtual LO leakage is primarily a challenge of meeting sp ... More

Add  Impact of the semiconductor diode structure on the virtual local oscillator leakage of GaAs sub-harmonic mixers
Authors: Gutta, Venkata | Parker, Anthony E | Fattorini, Anthony
Date: 2009
Subject Keyword: 090600 Electrical and Electronic Engineering | mixers | microwave mixers | millimeter wave mixers
Language: eng
Resource Type: conference paper
Identifier: http://hdl.handle.net/1959.14/118072
Description: Diode mismatch in an anti-parallel diode mixer results in an unwanted virtual leakage at twice the local oscillator pumping frequency. Random variability in a fabrication process is one of the sources ... More

Add  Microwave device model validity assessment for statistical analysis
Authors: Heimlich, Michael C | Gutta, Venkata | Parker, Anthony Edward | Fattorini, Tony
Date: 2009
Subject Keyword: 090600 Electrical and Electronic Engineering | CAD | design automation | design methodology | microwave circuits | electromagnetic analysis
Language: eng
Resource Type: conference paper
Identifier: http://hdl.handle.net/1959.14/115571
Description: Model accuracy is a key consideration when using circuit simulation for microwave designs in general but normally ignored in statistical analysis. A measure of model validity against process variation ... More

Add  Process-dependence of the even-order nonlinearity in anti-parallel diode pair mixers
Authors: Gutta, Venkata | Parker, Anthony E | Fattorini, Anthony
Date: 2009
Subject Keyword: 090600 Electrical and Electronic Engineering | microwave mixers | millimeter wave mixers | mixers
Language: eng
Resource Type: journal article
Identifier: http://hdl.handle.net/1959.14/85329
Description: Diode mismatch in an anti-parallel diode mixer can generate a product at the second-harmonic of the local oscillator frequency. This product is referred to as the virtual local oscillator leakage. Var ... More
