Reducing System Cost and Complexity

TWTAs can simultaneously transmit multiple carriers, taking the place of multiple KPAs. Multi-carrier operation with a single HPA can dramatically reduce installation and replacement costs. For example, a DTH provider with four channels to transmit can multiplex these with a 1+1 TWTA solution, requiring only two HPAs, compared with four online amplifiers and at least one spare for a klystron approach.

Flexibility for the Future

Expanding a DTH network using TWTAs is easy compared to a KPA approach. Carriers can be added without installing additional amplifiers as long as the system operates within the power and linearity requirements of the TWTA. This method is more flexible than the traditional approach of adding a new KPA for each added carrier and, it provides flexibility in the link for changes in power and linearity requirements per channel as the transmission standards change.

Maximizing this TWTA advantage, we offer the highest output power TWTAs in the industry, with up to 1250W at Ku-Band, 1250W at DBS-Band, and 650W at Ka-Band. Our TWTAs are available with options for extended bandwidth, Ethernet interface, predistortion linearizers, and integrated L-band BUCs.

The business case for our outdoor TWTAs in DTH uplinks is compelling. DTH providers benefit from a reliable solution offering reduced costs, lower electricity consumption and a reduction in facilities and ancillary equipment costs. Our long history of technology leadership in high power outdoor TWTAs for satellite communications and our outstanding record for reliability will help build your business and we will be there to support you in the future.
