Compact Dual-band Filtering Power Divider with Low Loss and High Isolation Based on Open-Circuited Stepped-impedance Resonators [PDF]

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
In this paper, a novel, compact, and high-performance dual-band filtering power divider is presented. The proposed circuit is constructed from a dual-band power divider and open-circuited stepped-impedance resonators.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

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 ...

Highly Unequal Three-Port Power Divider: Theory and Implementation

International Journal of Antennas and Propagation, 2018
A three-port power divider consisting of a directional coupler, a Wilkinson power divider, and two transmission lines connected to them is proposed. Theoretical analysis reveals that highly unequal power division can be achieved by a feedback mechanism ...

Ultralow phase noise microwave generation with an Er:fiber-based optical frequency divider

, 2011
We present an optical frequency divider based on a 200 MHz repetition rate Er:fiber mode-locked laser that, when locked to a stable optical frequency reference, generates microwave signals with absolute phase noise that is equal to or better than ...

Real‐World Pediatric Blinatumomab Administration: Access to Outpatient Care Delivery and Impact of a Hospital‐Dispensed Model

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Blinatumomab has been shown to be highly effective for patients with pediatric B‐ALL and has recently become standard of care therapy. Due to its past use in the clinical trial setting, there is limited information available about real‐world administration.

A Horst-Type Power Divider With Wide Frequency Tuning Range Using Varactors

IEEE Access, 2019
This paper presents a novel power divider with a wide frequency tuning range. In our previous work, a pair of capacitors were connected in parallel with the front transmission lines of a Trantanella-type power divider introducing an additional reflection
