BLF188XRS 1 KW LDMOS-FET LINEAR AMPLIFIER
EXTREMLY RUGGED STATE OF THE ART !!!
This ,BLF188XRS PnP amplifier ,was created to enable the use of the latest LDMOS-FET's device
This amp is using the latest state of the art XR device from NXP (former PHILIPS)
The board used is double sided plated G-10 board 3oz. copper (high current board)
Device is using the CLAMP way of attaching the device to heat spreader and is superior to the 2 screws method
since the entire contact area of the LDMOS is pressed against the heat radiator and not just the edges!! you can see it in the pictures.
