DVT250
250 W VHF DIGITAL TRANSMITTER
General Descr�pt�on
The DVT d�g�tal transm�tters l�ne has been des�gned for those appl�cat�ons
where qual�ty, rel�ab�l�ty, and performances are essent�al character�st�cs
together w�th a cost effect�ve solut�ons all �n a really compact 3RU equ�pment.
These new DVT250 d�g�tal transm�tters prov�de pre-f�lter power levels >
250Wrms w�th electr�cal performances over the top for DVB-T/H, DVB-T2,
ATSC, ISDB-T, CMMB, and other emerg�ng d�g�tal standards.
The f�nal stages are equ�pped w�th 6th generat�on LDMOS dev�ces offer�ng
excellent ga�n, eff�c�ency and l�near�ty performance.
