1-2 UHF Transmitter Instruction Manual UT-3 896 - 960 MHz
UHF Amplifier Instruction Manual UT-3 806 - 960 MHz : The amplifier module provides the
final stages of RF power amplification and harmonic filtering for the transmitter. This manual is
intended primarily as a reference since the amplifier module is adjusted at the factory.
Low Current Synthesizer Instruction Manual OS(R/T)-3 132 - 960 MHz: This manual pertains to
the enhanced synthesizer module.
UHF Rx/Tx Channel Designation Table UT-3 896 - 960 MHz: This document relates operating
frequency to the transmitter channel number (see section 2.2).
1.3 UT-3 896 - 960 MHz Transmitter Family Models
The UT-3 896 - 960 MHz line of transmitters has a single RF power output rating of 3.0 Watt, with
wide or narrow band FM (12.5 kHz or 25 kHz channels) and employs synthesizer based frequency
generation. The six basic (i.e. no options added) band specific models of the transmitter are as
follows:
• UT-3/900-SNB3 - synthesized, 896 - 902 MHz band, 12.5 kHz channels, 0.5 - 3.0 Watt
• UT-3/935-SNB3 - synthesized, 928 - 935 MHz band, 12.5 kHz channels, 0.5 - 3.0 Watt
• UT-3/950-SNB3 - synthesized, 935 - 960 MHz band, 12.5 kHz channels, 0.5 - 3.0 Watt
• UT-3/900-SWB3 - synthesized, 896 - 902 MHz band, 25 kHz channels, 0.5 - 3.0 Watt
• UT-3/935-SWB3 - synthesized, 928 - 935 MHz band, 25 kHz channels, 0.5 - 3.0 Watt
• UT-3/950-SWB3 - synthesized, 935 - 960 MHz band, 25 kHz channels, 0.5 - 3.0 Watt
The transmitter models are very similar and the transmitters' band of operation is determined by
select components in the synthesizer and amplifier.
