LINEAR POWER AMPLIFIER dual LDMOS HIGH POWER
EXTREMLY RUGGED STATE OF THE ART!! With VERY HIGH POWER LOW PASS BAND FILTERS. This dual BLF188XRS amplifier , was created to enable the use of the latest LDMOS-FET's device. The 2 x BLF188 are operated at half the rated output power (1400)each device runs at 750w out. This enables far better heat, dynamic range and headroom for the amplifier.
The dual BLF188XR amp has input protection of overdrive with special rf diodes. Also selectable input 5W max or 50W max with on panel indicator.A heavy duty RF relay or a vacuum relay (optional)is provided. A lighted band selector with led indicators. Thermal protection with thermal cut out fuse in case of over temp. High power forced air cooling.
This amp is using the latest state of the art XR device from NXP (former PHILIPS). Devices are 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.
Look here for more info. It will withstand 65:1 VSWR!!!!!! (full short at full power).
DEVICE IS MOUNTED ON A COPPER HEAT SPREADER AND A GOOD and heavy HEAT SINK. Heavy duty LOW PASS FILTER BOARD 3oz. A professional led bargraph output indicator. MINIMAL LOAD TRANSISTOR ptt CIRCUIT. ANALOG METER for voltages indicator.
