Universal QRP PA 30 dB Gain, 10mW in, 10W out
|As you probably know, the DL-QRP-AG Ten Watt Push Pull PA is s not available any longer due to the obselete Bipolar Transsistors 2SC1971. Within the last 7 years several hundreds of them have been built all over the world.
The new PA needs 10mW drive to produce a clean and linear amplified signal of 10 Watts RF. The VMOS we use could give us more the 15 Watt, but we desided to stay with the traditional 10 Watt boarder vor SSB QRP which also gives a more clean output by avoiding any overdriving.
The PA is a Push Pull design. We use the moder Mistubishi
It is mounted on two metall standoffs, the 3 Transistors will be screwed to the backplane of the enclosure.
A complete kit inculding a manual is available at QRP Shop or QRP Shop International. Preorders will be accepted starting July 10., shipment of kits will be started second week of August.
