A new concept in low cost, high performance RF filters, Trinity features exceptional thermal stability, superior electrical performance, and long term reliability. The Trinity combiner/mask filter features aluminum construction and a cavity design that ensures flexibility and unparalleled temperature stability. In tests, the Trinity aluminum filter outperforms more expensive designs, such as Invar filters. Invar filters need to be silver-plated, creating the risk of corrosion, and they cannot expand sufficiently to cope with high temperatures. Trinity's aluminum construction is corrosion-free and offers cool operation up to 75kW without the need for fans or tightly controlled room environments. Patent-pending thermal compensation technology reduces frequency drift to unprecedented levels. "The Trinity filter is the low cost, high power filter solution for DTV (Digital TeleVision) Transmitting TV using digital signals. The major DTV standards are ATSC (North America), DVB (Europe) and ISDB (Japan). All three use MPEG-2 video compression and Dolby Digital audio compression. DVB and ISDB also include MPEG audio compression. broadcasting," said Spencer J. Smith, Andrew Corporation's Vice President, Broadcast Products.

The FCC was created under the U.S. set a technical challenge by giving many broadcast stations adjacent channels for DTV broadcasts. The beauty of a Trinity filter is that its design is suitable for both upper or MORE lower (N+1 or N-1) adjacent channel signal combining. It also makes high power transmitters mask-compliant while minimizing DTV and NTSC (National TV Standards Committee) The committee that developed the television standards for the U.S, which are also used in Canada, Japan, South Korea and several Central and South American countries.
