3KW + 3 x BLF188XR LDMOS BOARD LINEAR AMPLIFIER
A very high power solid state linear amplifier board. This board is designed for three LDMOS-FET's BLF188XR operating in a push-pull circuit. These boards are the result of a long R&D into. LDMOS FET high power linear amplifiers. And using 3 devices was not a simple design task. Each node in the PP circuit uses 1 and a 1/2 devices so. Without real strain on devices. I have revised my design to improve matching and IMD figures. The board features a high power transmission line transformer wound on stacked ferrite toroids. For lower IMD, lower saturation. The dual sided 3 oz. And is 17 cm x 24 cm in size. All critical RF capacitors are ATC and silver tabs rf caps from Murata for best rf performance. Efficient feedback circuitry ensures stable broadband operation.
Very large tube or core Also as seen in ON9CVD study on Magnetics. Tested the 3kw board with 3x BLF188XRS on a full copper heat sink with.Clamping the devices and not just using 4-40 screws at the tabs Results are. Very good and when ran at 2000w out F2 and F3 were way down and very known. 10-11 MHz distortion of LDMOS (known physical property probably to the way the device is made). Over all a very stable and powerful board.
Look at input VSWR curve I have added. All below 1:1.5. A good power supply that can be used with my amps or boards can be found here. Or a nother type that can be used with abit lower amperage here.Please verify your address during checkout. We are not responsible for any wrong or undeliverable addresses.
