Description

R24G40GSB

Ultra Wide Band Low Noise Amplifier24- 40GHz

Amplifier Use
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 returnloss larger than 10dB relative to 50 Ohm within the specified operating band width.
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 thetypical 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 orcirculator should be used to protect the amplifier.

Ultra Wide Band Low Noise Amplifier 24 - 40GHz

Note: Maximum RF input power is defined to protect
the amplifier from damage.
Input power may be increased at the users own risk toachieve the full power of the amplifier. Please reference
gain and power curves and monitor the temperature.

Biasing Up Procedure
Connect input and output to 50 Ohm
Step 1 source and load with in band returnloss better than 10dB.
Step 2Connect Ground PinStep 3
Connect +5V bias voltage
Power OFF Procedure
Step 1
Turn off +5V bias voltage
Step 2
Remove RF connections
Step 3
Remove ground connection-45 ~ +85
(Case Temperature below 85°C)

Ensure that the power is off when connecting or disconnecting the input or output of the amp.
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 performance degradation or loss of functionality.
What is not covered with warranty?
Each RF - Lambda amplifier will go through power and temperature stress testing.
Since the die, ICs or MMICs are fragile, these are not covered by warranty. Any damage to these will NOT be free to repair.
