Amp boards

Post by M0DTS » Sun Nov 13, 2011 10:27 am

Hi All,

Just seen these on ebay:
120810260202

They need ~100mW drive for 2Watts output 23/13cm.

You would need another mmic beforehand to get more drive level from the digilite but could be useful to someone.

Also noticed that board a few days back Rob, the actual auction states it is for the board & MMIC device, seems you have to add the extra parts yourself, no mention of the specs of these parts, was thinking of ordering one but was put off by this.

Hi Tony,

if you email Chuck he'll send you some details. Not many extra components needed but they are all 0603 devices (10 caps and 2 inductors ) so " challenging " to solder, lol. Remember L5 on the DigiLite board?
