- In this video I show examples of how to use microwave modules to boost your experiments - it's like a microwave Lego ! - vk5fe@wia.org.au

With this unit you need just a -5 dBm generator/synthesizer as local oscillator to drive a level 15 mixer, like the ZMDB-44H-K from Minicircuits (0.01 to 40 GHz)

In this video a RF absorber was used to improve the conversion loss response of the homemade mixer and a graph is shown comparing the mixer versions

- My new 30 GHz down converter compared to the Minicircuits ZMDB-44H-K - How to expand the range of your spectrum analyzer using an external mixer as front-end - Measuring the performance of the ZMDB-44H-K

In this video I tested high quality RF RG405 SMA Amphenol connectors and compared to low cost Chinese connectors and the result was a bit surprising - do you agree? I have added afterwards the S11 performance of just the 50 Ohm load as a reference. Please see ruclips.net/video/wXMR2utkAkg/видео.html

In this video I show the latest version of my RF generator, based on the LMX2594 synthesizer from Texas Instruments

I included all measurements in the vdeo - if you get bored, just go to the summary (7:03 min)

A compact set of six 5 VDC power supply outlets, USB compatible.

A simple accessory you can assemble to accurately measure audio frequencies with a conventional low-cost spectrum analyzer

New version of the MiniCounter - 18 GHz. Sorry for some lack of enthusiasm, just recovering from Covid VK5FE@WIA.ORG.AU

Evaluating the down converter using a proper microwave generator

The second part of the video, showing the behaviour of the unit

Expanding your spectrum analyzer range. A K band down converter, extending the maximum frequency of the Keysight N9917A (18 GHz) spectrum analyzer to 28 GHz.

This new unit boosts the output level of the 16 GHz Local Oscillator shown in video #27 so it can be used to drive a level 15 mixer.
