DD0KP if you have entered the lookup table can you provide it to me ? Else I plan to do so and I can give it to you if you want.

Hi
You can look at www.w1ghz.org A Personal Beacon for 10 GHz. Link1 Link2
If you have an spare LNB you can give it 22 Khz (!!!) and listen to the 10.6 GHz Lo.

DD0KP Hi, there are some errors as specified in the datasheet at large dB diffs at high frequencies. Do you plan to correct them ?

Hi, it seems that is smd feedthrough capacitors

Hi,
PA0P what exactly are these two components? I have found some of these at power lines and I do not know what they are.

i2NDT the Murata LFB2H2G45SG7C093 needs decoupling capacitors at both input and output as it has low resistance, to ensure that no short circuit will occur.

Bias tee, working from 100 MHz to 3GHz at least. L= 82 nH , 2*C = 10 nF
These are the init values. It is based on a personally based PCB so I create 2 of them for the moment. One low freq version with 10 uH & 10 nF which is usable from 1 MHz to 1 GHz without loss and loose 5 dB at 3 GHz. The second with 100pF and 82 nH usable from 100 MHz to 3 Ghz.

The MURATA BPF is build. i2NDT if you need more info tell me.

Hi,
This is a lab step attenuator based on a eBay PCB PE4302 with 31.5 dB max attenuation with 0.5 dB step up to 4 GHz. Thanks to SV1EED for writing the source code to a ATMEGA8.
