Re: ERA-02 as a multiplier

Still using the 723 regulator?
That thing is so complicated to connect up compared with an LM317. And, I believe, a lot noisier.
Isn't it so old that the reference inside it is an actual Zener? If so, no wonder it's noisy.
I formally learnt about them in 1976 - remember it well.

The Gali-2 is good to 8GHz....... I ‘rats nested’ one from 1278 – 2556MHz, think I set bias at about 2.2-2.5V with a 723 regulator. Yet to build on a proper PCB.

Does anyone have experience of using the ERA-02 as a tripler from around 3.5 GHz to around 10.5 GHz? I know they work in triplers up to 3 GHz, but I was wondering whether they have a respectable performance higher up, or whether one needs
to use an MMIC that actually has some gain at 10 GHz.
