10W HF Linear Power Amplifier. Comfortably produces 10W from 12V supply. Compact design with huge heatsink included, which will not overheat even on continuous 100% duty-cycle operation. 26dB gain with +/- 1dB gain flatness from 2 to 30MHz.
This 10W HF Linear Power Amplifier kit has no Surface Mount Components (SMD) to solder. There are a number of small transformers to be wound, and assembly requires care and patience.
The push-pull driver stage uses two BS170 transistors in the amplifier design used in the SoftRock transmitter stage. The final uses two IRF510 transistors in push-pull. Yes, this humble low-cost MOSFET really is capable of excellent performance all the way up to 10m band and beyond! Short lead-lengths and PCB layout are extremely important, they are the key to success.
Hard-copy assembly instructions are not included in the kit. You need to download the assembly and operating instructions manual from http://qrp-labs.com/linear
NOTE: Any Linear should always be followed by suitable Low Pass Filtering
