I. DTXPRO-2.3KU INTRODUCTION
The DTXPRO-2.3KU transmitter is an integrated transmission system. Included in a 19 inch, 40
RU rack is a modulator, power amplifier, and combiner. The mask filter, low pass filter and
directional couplers are mounted external to the 40 UR rack. The DTXPRO-2.3KU 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 110V AC or any 48 VDC TELECOM back-up system should
the AC mains fail. Back-up DC supply is not included in this package.
The MFA2PAU-50ND amplifier assemblies 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
220V AC.
An FCC compliant stringent mask filter is supplied and installed external to 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-2.3KU for two (2) years from ship date. An
extended warranty is available for an additional five (5) years. Contact PTI sales for details.
