SMD Dummy Load BNC KIT

Description: Want to try SMD for the first time but don’t want to try a big project with tiny parts? This small QRP sized dummy load was designed as a learning tool for SMD soldering by using larger 2512 resistors for the dummy load portion. The 50 ohm load will operate from 500KHz to 30MHz with an SWR of less then 1.1:1 at power levels up to 20W under short durations. Usable at up to 225MHz with an SWR of less than 1.3:1. The circuit also includes a small tap for using an oscilloscope and a detector circuit for use with a DMM (or Arduino) to monitor your signal. The detector part of the circuit uses a SOT-23 type part, which are one of the next common smaller sizes. This is a KIT. Some basic electronic soldering experience is required. Printed manuals are no longer included. A link for a downloadable manual will be included with the kit or contact us for a copy. Picture with dime is for reference only - parts on this picture and the dime are not included.
