inside view
rf dummy power last 50Ω / 100 Watt, usable over 3000 MHz

RF power last is based on rf resistor 50Ω with max. power of 150 Watt, inductance 5 nH, tolerance 1% and temp. koef. 50 ppm/K. The resistor is fitted into two heat sinks made by Fischer Elektronik GmbH.

The power last is sized 100 x 100 x 116 mm.

VSWR at 3000 MHz is 1.09
