| Question: What are the certification requirements for a multi-channel power amplifier (MCPA)? |
Answer: A multi-channel power amplifier (MCPA) may operate under Parts 22, 24, 74, and 101 of the FCC Rules. The output level from a MCPA is dependent on the level of the input drive signal. The output power value listed on a Grant of Certification is the maximum output power capability of the MCPA, whether per channel or composite. An applicant may request that a comment relating this information be placed on the Grant of Certification. For units already granted, this can be done by filing a Class II permissive change request, pursuant to 47 CFR 2.1043. No measurement data are required for this filing, unless re-tuning / adjustment to the amplifier is required to achieve the lower output power level. Measurement data for operation at the new / additional lower output power level is required in the Class II permissive change filing.
