After I decided to make a waveguide coupler to see what results I may achieve, I have disassembled one and looked at its construction. Then I made my own coupler.

As I said, after I made my own waveguide termination, I wanted to make a directional coupler in waveguide. Here is my progress.

I want to do a few experiments with waveguides, this time I try to make a termination. Later I will try to make a directional coupler, so with the aid of the termination I can calibrate the directional coupler and do some measurements at higher frequencies.

I got a new 4262A LCR meter from eBay. It was sold ‘as is’ because it had a defect…

I was working quite a while on my GPSDO project. This post is still work in progress and I will provide some updates from time to time 😉

When I wanted to build a diplexer, I read that this can be done by using a highpass anda lowpass filter. But what if someone wants to make a multiplexer, or if one wants to use bandpass filters?

My next project is to build a GPS disciplined oscillator. I have bought a NEO6M GPS module (GY-GPS6MV2) which uses an active antenna. However, there are several drawbacks which I want to fix first.

My HP 8753C network analyser has options 010 and 006 installed, with 006 being the 6 GHz operation and 010 being time domain analysis. However, there is also option 002, which is called harmonic analysis.
UPDATE: I made a firmware dump & updated to the latest version!

I got a ‘new’ spectrum analyzer, which is a HP 8568B (100 Hz – 1.5 GHz). Unfortunately, it has some problems with the CRT, as well as some noisy traces.
