8 or 10 Ghz source

[eurofox]

Hi,

I need a low cost RF source in the area of 8 or 10 Ghz for testing purpose.

Thank in advance for input

How low cost?

Zcomm have VCOs up to 12 GHz

Hititte also make VCOs at that frequency that have /2 and /4 outputs making it easier to make a PLL to control the frequency.


If you'd rather have an old signal generator then the HP8672 is a useful beast, though a little large and heavy

I don't want to put a monster on my bench just for some test and pay 2K$ for it.

Zcom is perfect for me, I cannot find a distributor in Europe and just send them a email.

In the good old days I always had a microwave intruder detection sensor in the RF lab. They output a 10.xxx GHz signal from the transmitter horn and you have a good match into air. These make an excellent 'real world' over the air 10GHz source. Such can be useful when testing receiver and antenna combinations. The units I used to use were made by RACAL and were lumps of cast aluminium for the transmit and receive horns. Modern equivalents are a lot cheaper and use PCB patch antennas so are very compact. Always useful to have around

OR just a neat little PCB source

Just search for 'Doppler Radar'

The older models, that use the transmit and receive horns, are much larger than the modern version but you were able to modify them to work on other frequencies by changes to the microwave resonant cavity volume.

Thanks!

Very useful information, I order 2 PCB's, is all I need just a +/- 10 Ghz source, my RF generator go to 3.2 Ghz and just need for one test.
