Get one of these ...... Excellent value  ........... make's a tough job easier ..........

and get the 0.5 reducer ........... about £20 .... 

The ring light psu , is the best rf wideband source ever ............... so , swopped the dc socket wiring to a positive centre pole ,

and use a "normal" quiet dc supply ............... 


Incidently , for these very small packages , is there perhaps , a small infra red "iron" type device for soldering them in place ....

Where's your spirit of adventure !
A 1mm long package with three pads is no big deal ;-)

And nearly twice the gain.

Looks like a useful device, though the 1x0.5mm package might be interesting to handle :-)
Seems to be a 3-lead 0402, so not quite as challenging as some of the other tiny
packages - I'd be prepared to give it a go anyway.

Found this one at Farnell    http://www.farnell.com/datasheets/77793.pdf

Fixed 5V bias, over 13dB at 10GHz  and a not outrageous noise figure by the look of it.

More expensive than the  ERAs used to be though, but at that gain probably replaces two cascaded..
