Assuming the MMC amps can work without the issues that are being pointed out, the idea of using an assembled amplifier board, for us retrofitters (like the assembled filter boards folks are creating)

I just noticed that from the first picture it's not so clear about what connector I was talking about, so I'll upload a new picture.

Hi everyone, again! Today I got a really big present from PostNord Danmark. They arrived at my house with a small box shipped from INDIA. Of course, it was my new uBitx. Yay !?The shippment was

Allison, why would the MMICs oscillate and not a 2N2219A? Might screening of the mmic help? that provides 20 dB of gain nearly flat out to 4 GHz with a 1 dB compression point at +18 dBm. It is 50 ohm

Expliquer en anglais, s'il vous plait. Allison

Warren, Both Jerry and I tried? that.? I use MAV11 a lower gain higher output part and getting to oscillate in ubitx environment was trivial.? Getting non-oscillation was very very difficult.?

Allison, Yes, it's like herding cats ......? many different ideas, many cats. 73 Kees K5BCQ? ajparent1/KB1GMX ( /g/BITX20/profile/383014 ) 8:00am???#59377??(

I have ordered many small parts off ebay from China. One has to be very careful as there seem to be many substandard parts. You may get a good batch from one source and a bad batch from another. I

Ok Warren, sv1avn is a good supplier as rf-microwave is, of course if you test the mmic from the Chinese supplier are ad good too I might well consider it. Thanks for testing them and keep us

If yours has 16 pins along the bottom you got a raduino configured for the ?BITX.? The BITX40 raduino has 8 pins on top and 5 on the bottom.? Except for the pins the hardware is the same and you

The 23 dB gain, 2.4 GHz MMC amp module I tested is here:?https://www.sv1afn.com/wideband-mini-amplifier.html? ? ?It costs $17 delivered from Greece. WA8TOD

Sorry Iz, I mis-typed. It is the ERA-3SM+ that is available for less than 1USD on eBay. It is from a Chinese supplier so it will require due diligence in testing.?

Warren, from Rf-microwave, which is a reliable supplier, they cost more than 6Usd each. Can you provide us the name of the ebay seller that offer Era5 at 1Usd really made by Mini Circuits?

There is a much better way. Very radical but probably less costly and better performance? The Mini-Circuits ERA-5+ MMIC is a single, pin head sized gain block that provides 20 dB of gain nearly flat

hi the wire up instructions talk about the top side and the bottom side but which is top and which is bottom it says to connect the 5 pin to the bottom side - is that the 16 pin connections and if it

Ralph yes right here about 6 wweeks ago. We repeat everything here at at least 5 times.? Sometimes more. Allison

Yes! and over 200 posting about it. And no forcing 3904s to marginal gain.? Throw the damn things out.? If you want to use them do it right rather than struggling.? First 5 stages at low gain, its
