Abstract: High-Frequency Reference Design (HFRD)-26.0 is a Small Form Factor (SFF) host board designed for evaluating GEPON and GPON SFF modules. The host board can be used to test a variety of different modules, but includes additional features for testing, monitoring, and programming HFRD-25.2 (Low-cost GEPON SFF ONT with µC). Features include: SFF MSA Compatible GUI Interface with USB Connection SMA Connectors for High-Speed Data Schematics and Bill of Materials Provided Gerber Files Available
BFU520W Evaluation Board for Automotive Remote Keyless Entry LNA Applications at 315, 434 and 868 MHz
Low noise amplifier BFU520, BFU530 and BFU550 customer evaluation kit for SOT143 packaged transistors
0-30V 0-3A DC regulated power supply circuit
This reference design is for a highly efficient, active-clamped forward, dual 3.3V/8.8V-output powered device (PD). The design features the MAX5969A and MAX5900 as its controllers. The design also uses the MAX5974C, which controls current-mode PWM converters and provides zero-voltage switching (ZVS) and frequency foldback to enhance supply efficiency. Using these devices, this RD is IEEE® 802.3at compliant and is a high-performance, compact, and cost-efficient solution for PoE and nonstandard high-power PDs. The design can also support the auxiliary input voltage to provide maximum 55W output power.
