Ryan, The output of the circuit is about 0.025 milliwatts. Not even enough to go across the room! The pa is posted on the wiki at www.hfsignals.org. But a simpler linear is in the works. - f Sent from BlackBerry® on Airtel -----Original Message----- From: Ryan Kingsbury <ryan.kingsbury@xxxxxxxxx> Sender: minima-bounce@xxxxxxxxxxxxx Date: Tue, 4 Feb 2014 10:35:52 To: <minima@xxxxxxxxxxxxx> Reply-To: minima@xxxxxxxxxxxxx Subject: [minima] Minima power output Hi folks, I should probably be melting solder rather than scratching my head about how the design is supposed to work but...I have some unanswered questions about the design. On the Minima website, it states that the design features 1 watt output power in the summary towards the top. Surely this is a typo? Unless the mixed formed by T1 provides a significant amount of gain, I can't imagine that the IF amp (Q6,7,8) is pushes more than a watt through the crystal filter, mixer and LPFs. Further down, in the design history sections, it says the output power is 1 mW (0 dBm). This seems much more believable to me. If combined with a PA, such as the JBoT, then I can see how the combination could deliver 1 W. Could someone else confirm? Thanks in advance for the advice. I promise to start melting solder soon! 73, Ryan (AG4ZP)
