A Broadband Balun With Complex Impedance Transformation and High Isolation
IEEE Access, 2019 The design of baluns with wide bandwidth, transformation between complex source and load impedances, and high isolation is presented in this paper. These features can be accomplished simultaneously by employing double-stub couple lines (DSCL).

Optically coupled high-voltage isolation amplifier [PDF]
Review of Scientific Instruments, 1978 A common and persistent problem in modern instrumentation is the observation and recording of small signal waveforms that are removed from ground by very high voltages. Examples of this are the instrumentation of neutral particle injectors used in controlled thermonuclear research and the construction of safety breaks for air core toroidal devices.

A wideband CPW ring power combiner with low insertion loss and high port isolation [PDF]
, 2012 In this paper we present a coplanar waveguide (CPW)-based ring power combiner that exhibits less than 0.8 dB insertion loss, better than 15 dB port match and higher than 22 dB isolation loss over the frequency range from 50 GHz to 100 GHz.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
