LPA-2 50/100W Linear Power Amplifier
Brand: PulsarThe LPA-2 is the next generation high-power amplifier for Power Line Carrier Communications and adds features and efficiency superior to all previous designs using the latest technology.
It offers flexibility plus user-friendliness on its input and output such that it can be used with any power line carrier system. Two 50 W units can be combined for a 100 W output and to provide redundancy.
Although primarily used in applications where the attenuation from end-to-end is higher than the normal 10W amplifier can handle, the LPA-2 can be used in normal applications to boost system dependability by significantly improving the possibility of the PLC signal not being lost during a high noise event.
Modern design makes the LPA-2 able to protect itself against shorts or open circuits on its coax cable output as well as against being overdriven on its input. Once the issue is removed it will automatically recover without damage to the unit.

Output Impedance
- 50 Ω
Maximum RF Power Input
- 10 W (+40 dBm or 22.4 V, 50 Ω Reference)
Recommended RF Power Input
- 5 W (+37 dBm or 15.8 V, 50 Ω Reference)
Minimum RF Power Input (To Get 50 W Output)
- 2 W (+33 dBm or 10 V, 50 Ω Reference)
Maximum Power Output
- 50 W Continuous Single Frequency into 50 Ω Load (+47 dBm or 50 V, 50 Ω Reference)✦
- 50W is replaced by 100W (+50 dBm) when two units are combined to give 100W output with a built-in combiner board inside one of the two units. Inputs of the 2 units are paralleled in this case with one set for 50 Ω and the other for 5K Ω input impedance
