Amplifier Use

Power Supply Requirements
Power supply must be able to provide adequate current for the amplifier. Power supply
should be able to provide 1.5 times the typical current or 1.2 times the maximum current(whichever is greater).
In most cases, RF‐Lambda amplifiers will withstand severe mismatches without damage.
However, operation with poor loads is discouraged. If prolonged operation with poor or
unknown loads is expected, an external device such as an isolator or circulator should be
used to protect the amplifier.
Ensure that the power is off when connecting or disconnecting the input or output of theamp.
Prevent overdriving the amplifier. Do not exceed the recommended input power level.
Adequate heat‐sinking required for RF amplifier modules. Please inquire.
Amplifiers do not contain Thermal protection, Reverse DC polarity or Over voltage protection
with the exception of a few models. Please inquire.
Proper electrostatic discharge (ESD) precautions are recommended to avoid performancedegradation or loss of functionality.

Ultra Wide Band 8W Power Amplifier 2-20GHz

Ensure that the amplifier input and output ports are safely terminated into a proper 50 ohm
load before turning on the power. Never operate the amplifier without a load. A proper 50
ohm load is defined as a load with impedance less than 1.9:1 or return loss larger than 10dB
relative to 50 Ohm within the specified operating band width.

What is not covered with warranty?
Each of RF‐Lambda amplifiers will go through power and temperature stress testing.
Due to fragile of the die, IC or MMIC, those are not covered by warranty. Any damage tothose will NOT be free to repair.
