High frequency transformation ofKalanchoe laciniata

Plant Cell Reports, 1989
Leaf explants ofKalanchoe laciniata were cocultivated for different days (2, 4, 6 and 8 days) with disarmedAgrobacterium tumefaciens strains A208SE, GV3111SE and EHA101 carring a binary vector pROA93. The vector contains a cauliflower mosaic virus 35S promotor which drives the coding sequence of neomycin phosphotransferase II (NPT-II) in one direction ...

High frequency transformer modeling

ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2002
This paper presents a technique of indirect measurement of linear and nonlinear elements of a wideband transformer using the reflection coefficient technique with the scattering matrix (S-parameters). The S-parameter frequency domain measurement method of the wideband RF transformer and conversion into a discrete model is discussed. The leakage and the

Difficulties in high frequency transformer modeling

Electric Power Systems Research, 2016
Traditional transformer models available in EMTP-like software packages are not capable of representing transformer behavior during a transient state, which includes high frequencies, since they usually do not adequately take into account the transformer resonant behavior caused by its highly complicated design.

High frequency-selectivity impedance transformer

2015 IEEE Radio and Wireless Symposium (RWS), 2015
This paper presents the design of an impedance transformer (IT) with high selectivity and wide out-of-band suppression characteristics. The proposed IT provides two transmission poles in the passband and a sharp frequency selective characteristic. For validation, a 50-to-20 Ω IT has been implemented at a center frequency (f 0 ) of 2.6 GHz.
