From now until the end of the year please expect extended shipping times due to the Holiday volume. Last year, 3-4 week transit times were not uncommon.
This store has tools you need to add RF Power. Whether you have a premade QRP transceiver, a low cost SDR or a homebrew project, we have amplifiers and supplies for you.
Here is a 5W output 1-55 MHz amplifier for stand-alone QRP operation or to drive the 100W MRF101 or 500W AN1819 amplifiers to full power with lower drive level.
The amp can be built with only the output stage for a drive of 100-200 mW or add an MMIC to lower the drive to the 1-2 mW range.
The circuit uses a NXP AFT09MS015N with a 4:1 output transformer which can develop over 7W with 13.8V DC input.
The gain is about 20 dB with the output stage alone and about 40 dB with the MMIC. The input has a place for a resistie attenuator so you can adjust the gain for your system.
We are experts in RF power amplifiers. Our products are designed to give you the flexibility to create working amplifiers from a useful toolkit of products.
