Publication number: 20230411564Abstract: A light-emitting diode (LED) and a manufacturing method thereof are disclosed. The LED includes: a substrate, a light-tight reflective layer, an inner epitaxial layer, an outer epitaxial layer, a non-conducting layer, an ohmic metallic body, a first electrode, and a second electrode. The inner epitaxial layer and the outer epitaxial layer are separated from each other by a separation space. In a view made from a top side of the LED, the separation space forms a closed path and surrounds the light exit hole. The separation space provides an effect of blocking an electrical current and a light emission area in the inner epitaxial layer. By redirecting light emitting from a lateral side of the inner epitaxial layer toward a top side of the LED, the LED shows a low side light ratio.Type: ApplicationFiled: January 19, 2023Publication date: December 21, 2023Inventors: YUAN-HUI FU, YI-HUNG CHEN, TAI-HSIANG HU

Patent number: 11553857Abstract: A radio frequency (RF) front end device has a signal traveling from a first antenna to a second antenna in an uplink path and a signal traveling from a third antenna to a fourth antenna in a downlink path. The device is under the control of automatic on/off controller (AOOC) which upon receiving a signal indication from a receive signal detector and amplifier (RSDA) turns on the operations of power amplifier (PA) and simultaneously turns off a low noise amplifier (LNA). This LNA is turned off when the power amplifier is turned on to prevent uplink path and downlink path forming a feedback loop which would result in oscillation, noise and interference.Type: GrantFiled: January 30, 2021Date of Patent: January 17, 2023Assignee: Micro Mobio CorporationInventors: Zlatko Aurelio Filipovic, Weiping Wang, Adam James Wang, Guan-Wu Wang, Yi-Hung Chen
