Circuit ideas:

A very sensitive peak detector:

Ten times more sensitive than a detector using hot-carrier diodes, can be used to implement highly accurate measuring instruments. Works up to UHF frequencies and beyond.

Binary step attenuator:

Made with stripline technology andi SMD resistors, it is accurate within 1 dB up to 500 MHz. Lets you choose any attenuation value from 0 to 79 dB in 1 dB steps. Input and output are adapted to 50 ohm.

Electric diagrams are done with ^©ISIS Lite , Printed circuit boards are done with ^©ARES Lite ; both programs are available as shareware by ^©Labcenter Electronics at their website http://www.labcenter.co.uk/ where you can also download ^©PROTEUS IV , demo version, a complete package for electric schematics drrawning, PCB design and circuits simulation.
