Often it is the power amplifier which needs to be replaced as many models of linear or early switching amplifiers have parts which are becoming obsolete. The key benefits of renewing the amplifier are increased time between failures, reduced time to repair and greater operating efficiency. Eliminating the water-cooling used on earlier linear amplifiers greatly simplifies system maintenance. Also, the floor space required is reduced, compared to earlier amplifiers.
1g-dynamics has recent experience of supplying and installing new power amplifiers of up to 200kVA output rating to a major satellite manufacturer. A designated engineer, who will see the contract through from initial quotation to final acceptance test and sign-off, manages projects such as this. This gives the customer the highest level of confidence that the work will be carried out efficiently and the final system will achieve the expected system performance.
