When specifying a new amplifier there are a number of important considerations to be made. Here are some of the top tips from the experts at Exodus Advanced Communications to aid in your selection process:
Determine the Frequency range of operation needed, sometimes more than one amplifier is required.
Determine if you need a Pulse or CW type of Amplifier.
Example: HIRF EMC applications require High Power Pulse Amplifiers.
Determine the minimum power needed from the amplifier.
Example: As you go up in frequency antenna gain improves so a lower power amplifier may be acceptable.
Assess the system losses between the amplifier and the Antenna/DUT.
Example: If the test setup has 6dB of losses then the Amplifier power needs to be 6dBm higher.
Some modulations if required for the test application, would require a higher power amplifier.
Example: When performing an 80% AM modulation test the amplifier needs to have 5.1dBm of margin to accommodate the peak.
Antennas, Cables, DUT’s & Rooms have cumulative VSWR, it is best to allocate for some power margin.
Consider the application, is this a single test or will it be used repetitively.
Consider your desired RF connection types and locations optimal for your application.
Also, consider if automation will be used so the appropriate remote capability is included.
