300 W PEP with BLF177(1.6 ... 28 MHz)

 300 W PEP with 2 MOS transistors BLF177(1.6 ... 28 MHz)

The BLF177 is an RF Power MOS transistor for the HF and VHF range in a 4 leads flange SOT121 encapsulation. For the frequency range 1.6 - 28 MHz a wideband push-pull power amplifier has been developed with 2 BLF177 having an output power of 300 W PEP at an intermodulation distortion level below -30 dB.

The transistors operate in class-AB at VDS = 50 V and a quiescent current of 0.5 A each.

CONSTRUCTION OF THE AMPLIFIER

r = 4.5. The position of the components is on one side and the other side serves as a groundplane. Connections to the groundplane have been made with rivets and with straps under the source leads and at the edges of the PC-board on the in- and output side.eFor the printed circuit board double Cu-clad epoxy fibre glass has been used with a thickness of 1/16” and

The printed circuit board has been attached to a solid copper plate which functions as a heatsink.

Around the position of both transistors a tube has been soldered in the copper plate to controle the temperature by means of a watercooling system. For a good thermal contact between heatsink and transistors heatsink compound has been used.
