Hello i want to know the simple way to convert 13cm ..23cm.. 70cm to 10 ghz ? and how we call this process

thx

Hi Aldo

You just need to use a transverter - the same as you would use for narrow-band. For example (although expensive) http://shop.kuhne-electronic.de/kuhne/e ... -band_ws=3

thx im poor man will be great to post a link with shematic and pcb then i can build it alone thx a lot

Question : if need just use 10 ghz tx i must use mixer with 10 ghz oscillator if i need use tx and rx must use tranverter thats right ?

No one can help with good mixer shematic ? From 23cm or 70 cm to 10 ghz ?!!

I'm putting together a 437MHz to 10GHz transverter at the moment. For simplicity and to avoid soldering tiny components, I'm using a packaged double balanced mixer MC64PG-11. There are plenty on eBay - cheapest is £38. MiniKits have a range of the bare mixer devices, but few go to 10GHz and some are hard to solder.

I'm looking to get onto 10GHz. I've got a couple of HackRF SDRs and I can generate DVB-S on 23cm with them. So what I'd like to do is generate the signal at 5184MHz and mix that with unmodulated 5184MHz, for signals at DC and 10.368GHz. Any recommendations for a mixer that can take a 5GHz IF signal?

Most of us use commercial transverters from DB6NT to go from 144 or 437MHz up to 10 GHz - not cheap but work well.

However, there was an Interesting post on the Yahoo UK microwave group about this project: http://www.w1ghz.org/MBT/Simple_and_Che ... 10_GHz.pdf It looks an excellent simple design and I believe PCBs are available.

But the suggested LO solutions look as complicated to a beginner as the transverter does and I wonder if the ADF4351 plus a simple pipe cap tripler (or the higher frequency ADF part) could be used as the LO? It would make things simpler, there are designs around for a simple PIC controller and it can easily be GPS locked.

Food for thought.

People have looked at this with the Ettus B210 USRP see: https://sourceforge.net/p/sodaradio/wik ... RP%20B210/ and they used a Watkins Johnson M51C coaxial mixer.

A better solution for DATV is perhaps as Noel suggests. Generate an LO around 3 GHz from an ADF4351 and either triple it and filter to you can use a surplus standard packaged mixer up from 23cms, or use a harmonic mixer. If you are using the ADF3451, careful choice of frequency and registers will allow you to minimise the phase noise.

I have my YIG oscillator / MC64PG-11 mixer based 10GHz transverter working in lash-up form, but the close-in phase noise is not good and I want to use it for NB as well with the the FT817. I also want to go the ADF4351 tripler route. I've listened to the 3rd harmonic of the ADF4351 on 10368MHz through an Octagon LNB and I can't hear any unexpected noise when I tune across it on SSB.

The harmonic output of the ADF4351 is appreciable as it stands. I set it to 3456MHz and fed it directly into a 15dB horn and was received on 10368MHz by G3UVR 5km away. I'll need extra gain for the LO and after the mixer to drive the DG0VE amp. The only MMICs I've found that go to 10GHz are NLB-310. Minikits have them at about £4. Mouser have them, but more expensive. Perhaps BATC would consider stocking them.

For 10GHz gain stages you can use parts of old LNB boards, most will do but some are more useful than others...

These in particular are easy to modify for your own purposes:

See the datasheet on the page for modifications.

They also make good 5.6/8.4/10GHz LNA's.
