I. DTXPRO-800U INTRODUCTION
The DTXPRO-800U transmitter is an integrated transmission system. Included in a 19 inch, 24
RU rack is a modulator, power amplifier, mask filter, and standard accessories. The DTXPRO-
800U is tested to FCC specifications.
The modulator used in this assembly is the DXDPRO-10U. The DXDPRO-10U is a UHF 8vsb
broadband modulator with adaptive linear and non-linear correction controllable via an Ethernet
IP connection. Many additional features are included in this basic modulator such as transmitter
remote control and status monitoring, GPS receiver, ASI or SMPTE 310M, and fault notification
via email. This unit will operate with 110 VAC or any 48 VDC TELECOM back-up system should
the AC mains fail.
The MFA2PAU-50ND provides power amplification to achieve the desired power output level to
comply with FCC license requirements. LDMOS 50 volt device technology is used throughout the
HPA section for state-of-the-art performance. This unit is wired to operate off 220 V AC.
An FCC compliant stringent mask filter is supplied and is built into the rack. Additional
components are included to sample forward and reflected power as well as samples for the
adaptive linear and non-linear corrector. The system transmitter is protected using an Isolator
between the mask filter and the HPA. Any failures in the filters or antenna will be detected by the
onboard protection circuits. This transmitter includes a low pass filter for additional harmonic
suppression in the GPS bands.
Pineapple Technology, Inc. warrants the DTXPRO-800U for two (2) years from ship date. An
extended warranty is available for an additional five (5) years. Contact PTI sales for details.
