2KW+ 2 x BLF188XR LINEAR power AMPLIFIER
A very high power solid state linear amplifier board. This board is designed for two LDMOS-FET's operating in a push-pull circuit. A Variety of RF LDMOS-FET'S can be mounted on the board. 2x BLF 188,188XR 2400w out. (in my tests the 178 and 188 gave the best IMD results). These boards are the result of a long R&D into. LDMOS FET high power linear amplifiers. I have revised my design to improve matching and IMD figures. The board features a high power transmission line transformers wound on stacked ferrite toroids. For lower IMD, lower saturation. And higher power output the board employs special quality coax yielding highly efficient impedance transformation. The dual sided PCB is plated. And is 13 cm x 26 cm in size. All critical RF capacitors are ATC for best rf performance. Efficient feedback circuitry ensures stable broadband operation. I will supply all details upon request. Bias is regulated on-board and thermally fused for extra protection. Thermal tracking of bias is also provided on board. This is a populated board but without the active LDMOS devices. The board is supplied ready for your devices to be dropped in. These are very high power boards. The board has enough "headroom" to cover up most minor operating mistakes.
A good power supply that can be used with my amps or boards can be found. Please verify your address during checkout. We are not responsible for any wrong or undeliverable addresses. Items will be checked carefully before sent out.
