Web20 W HF Power Amplifier - A HF power amplifier with a push-pull of AFT09MS015N. The (small-signal) gain of the amplifier is around 26 dB in the lower HF band and goes down to about 24 dB on the higher end and still around 21 dB at 50 MHz. Its input matching is relatively good at the lower HF and degrades above 10 MHz. WebLow-power fluid automation technologies have evolved to include valves that draw as little as 0.55W. This technology provides savings with less power consumption and lower …

Build an AM Transmitter for Use with Antique Radios

WebA low value resistor (a few hundred ohms) is connected in series with the cathode, and carries a similar current to the anode. The voltage drop across this resistor (R34) holds the cathode a few volts above the ground level. The cathode resistor is sometimes bypassed with a parallel capacitor (C57), typically 25uF or 50uF.
