Shift frequency 2.4 GHz or 5 GHz to 17 GHz: RF Multiplier

[magnavox]

Hello to all!

On many countries, another unlicenced range is the 17GHz.

I an idea: to use standard RF modules 2.4GHz/5GHz to work at 17GHz.
A few manufactures procudes 17GHz wireless device.
I think that they have simply inserted a RF Multiplier betwen device and antenna.

Somebody can help my?

Tnx!

18 GHz equipment tends to be carrier grade, costs many thousands of dollars, and tends to be much higher quality than WiFi. 17 GHz is probably similar.
There is a lot more to it than the frequency.

Not 18 Ghz. The devices that I talk (working a 17 GHz) are sure a Mikrotik based…

Tnx to all!

hi,

such a device is a transverter. it mixes your existing frequency with a higher one and filters/amplifies the product required at 17GHz.

We have made these beasts for 24 GHz etc.. making one for 17GHz wouldnt be difficult but would be interested to know how widespread this 17GHz allocation is?

In the range 17,1-17,3 GHz can operate HIPERLAN devices CE and compliant whit CEPT ERC/REC 70-03.

Can you help me?

hi,

hiperlan is as far as i know a dead duck… 5.8 was for hiperlan but it didn’t happen it seems.

Would be interested to know if 17ghz was usable if allocated to a defunkt tech.

Alternative to HIPERLAN, for backbone?

My idea is to use a RF range whit less interferences (and RADAR events).

Have you actually ever seen a Mikrotik based 17 GHz device?
My educated guess is that it would be too costly.

Have you thought about looking at 24 GHz, 38 GHz or 60 GHz equipment?
The licensing cost is low in many countries.

Mikrotik and miniPCI radio modules not supports 17 GHz, this is true.

This manufacter (17 GHz equipement) produces many devices based on MT board,
in 802.11a/b/g standard (2.4 GHz and 5 GHz).
The same manufacter produce many RF modules (i.e.: Frequency multiplier).
I think that theri solution is: standard MT device + simply RF module…

Licensing? I prefer unlicenced range…

Tnx!

wow!

1. This module, work fine or is only prototype step?
2. How much’s this module?
3. This module, convert from/to GHz?

I m not a RF expert, can you explait:

• PA
• LNA
  
  
  tnx

hi,

almost begs the question , how much would people pay for such an item

If only we weren’t so busy installing infrastructure+customers we would look into making small cost effective transverters. The design software we paid $20,000 some eyars back is getting a bit dusty as is the Infra red reflow machine

here is something we designed/made some years back, way before the days of XR and R52H type cards.

this is the pcb of a 5.4-5.8GHz PA/LNA, capable of 30dBm peak, ~26dBm avg.
And this is the first built prototype which to this day lives in a tranzeo box AP on our network.

Low noise , ~1.3dB NF, narrow band LNA with 15dB gain and 15dB gain P.A.
And before the mods scream “Advert”, we never sold any of these

the parts were hand placed by me and reflowed afterwards, acquired skill

Interesting!

Which SPDT,RF detector and PA chip are you using?

[ottife]

I made a transverter to make WiFi working on VHF spectrum (240MHz) with TX power 3000mW.
But the performance seems no good,the coverage can reach 5Km but the bandwidth limit less than 500Kbps.
I cannot make anymore improvement after hard effort,then have to gave up.
