Publication number: 20240106551Abstract: A radio frequency (RF) test device such as a spectrum analyzer may include an RF attenuator to attenuate a received RF signal; a mixer to down-convert the attenuated RF signal; an IF attenuator to attenuate the down-converted signal; an analog-to-digital converter (ADC) to digitize the attenuated, down-converted signal; and a processor, which may select attenuation values for one or more of the RF attenuator and the IF attenuator based on an error magnitude vector (EVM) analysis, an RF signal type, and/or a signal level at an input of the ADC. The processor may use a look-up table for the selection. Initial attenuation values may be selected based on an expected RF signal type, RF signal frequency, and/or RF signal bandwidth. The attenuation values may also be selected in an iterative manner stepping the attenuation values up or down.Type: ApplicationFiled: September 27, 2022Publication date: March 28, 2024Applicant: VIAVI SOLUTIONS INC.Inventors: Bon-Jin KU, Seung-Gon HONG, Chang-Hyun PARK

Patent number: 11646425Abstract: A battery having an electrode assembly comprising a cathode having a cathode collector coated, partially or entirely, with a cathode active material, an anode having a nano-web layer on both sides of an anode collector coated, partially or entirely, with an anode active material, and a separation membrane interposed between the cathode and the anode; an electrolytic solution; and an exterior material which encapsulates the electrolyte solution and the electrode assembly together. Since the battery has a porous nano-web layer, even if the temperature inside the battery increases to cause shrinkage or melting of the separation membrane, a contact between the cathode and the anode is prevented such that ignition and/or explosion of the battery does not occur, ion exchange is not disturbed such that the battery performance does not deteriorate, and the nano-web layer is not molten or released towards the separation membrane even at high temperatures.Type: GrantFiled: April 20, 2018Date of Patent: May 9, 2023Assignee: Amogreentech Co., Ltd.Inventors: Jun Keun Cho, Kyung Pyo Hong, Dong Woo Kim, Seung Gon Park, Seung Yun Roh

Patent number: 11489165Abstract: Provided are an electrode wherein a short-circuit preventing film laminated on the surface of the electrode can prevent a short circuit between a cathode and an anode when a battery is overheated; a secondary battery using the electrode; and a method for manufacturing the electrode. The secondary battery electrode includes: an electrode current collector; an active material layer formed on the electrode current collector; and a short-circuit preventing film laminated on the active material layer, wherein the short-circuit preventing film includes a nanoweb type porous membrane which is formed by integrating nanofiber strands obtained by electrospinning polyacrylonitrile (PAN).Type: GrantFiled: August 28, 2018Date of Patent: November 1, 2022Assignee: AMOGREENTECH CO., LTD.Inventors: Seung Yun Rho, Dong Woo Kim, Seung Gon Park

Patent number: 11018379Abstract: Provided are an electrode capable of preventing separation of a short-circuit prevention layer since the short-circuit prevention layer, which is made of a heat-resistant polymer fiber, can be attached with high binding force when formed on the surface of the electrode, in the case that an active material layer includes a predetermined amount of polyvinylidene fluoride (PVdF) as a binder; a secondary battery using the same; and a method of manufacturing the electrode. The electrode includes: an electrode current collector; an active material layer formed on the electrode current collector; and a short-circuit prevention layer formed on the active material layer, wherein the short-circuit prevention layer includes a porous polymer fiber web having a plurality of pores through accumulation of ultrafine fibers of a heat-resistant polymer material, and the active material layer includes PVdF as a binder.Type: GrantFiled: September 19, 2017Date of Patent: May 25, 2021Assignee: AMOGREENTECH CO., LTD.Inventors: Seung Yun Rho, In Yong Seo, Ju Hyung Kim, Su Yeon Lee, Seung Gon Park, Dong Woo Kim
