10 GHz

One thing that became apparent when using a single XDK PLL board in a dual-band 2.4/3.4 GHz transverter system, is that the PLL’s limitation on producing even MHz only, necessitates using different IFs.

For 2403, (1970 LO), a 433 MHz IF is required.… Read more...

I was caught by surprise out in the field the other day, when my new Kuhne MKU 10 G3 432 appeared to not work.

But it worked fine on the shack bench.

Unlike my Kuhne MKU 57 G3 432, it did not like being powered up, with the 10 MHz external reference already connected to it.… Read more...

There aren’t too many pictures on DEM’s website, but here is a quick look at what this kit contains.… Read more...

Here is a quick review at the RF Ham Design tri-band ringfeed for 9, 6 and 3cm, model # FPF R963, and accessory mounting bracket, CLX-1.

Although RF Ham Design produce quite a number of [url=http://www.rfhamdesign.com/products/parabolicdishkit/dishfeeds/index.html]parabolic dish ringfeeds[/url], and already having a gridpack for 2.4GHz, the tri-band feed for 3400MHz, 5760MHz and 10368MHz was of interest.… Read more...

The Kuhne MKU xx G3 432 transverter modules have inbuilt OCXOs LOs (Oven Compensated Crystal Oscillator Local Oscillators), and whilst very good, they can be locked to an external 10 MHz reference from a GPS Disciplined Oscillator (GPSDO), such as a Trimble ThunderBolt.… Read more...
