Title: Jinhan Fan: Innovator in Radio Frequency Technology
Introduction
Jinhan Fan is a prominent inventor based in Shanghai, China. He has made significant contributions to the field of radio frequency technology, holding a total of 4 patents. His work focuses on enhancing the performance and efficiency of radio frequency antenna switches.
Latest Patents
One of Jinhan Fan's latest patents is a radio frequency antenna switch that includes an antenna port, a radio frequency signal port, and at least one branch coupled to either the antenna port or the radio frequency signal port. Each branch consists of multiple transistors arranged in a stacked manner. The design features a progressive decrease in channel width to length ratios of a preset number of transistors as they move away from the antenna port. This innovative approach increases the capacitances of the transistors near the antenna port while reducing the distributed voltages that these transistors must bear when in an off state.
Another notable patent by Jinhan Fan also pertains to a radio frequency antenna switch. This invention includes an antenna port, a radio frequency signal port, and at least one branch connected to either port. Each branch comprises multiple transistors with a multi-finger structure. The design incorporates at least one first finger used as a source and at least one second finger used as a drain. The connection of these fingers is facilitated by multiple vias, with the number of vias progressively decreasing in a direction away from the antenna port.
