R&S®VHF/UHF Multichannel Transmitters

VHF R&S SU452U(.), UHF R&S SD432U(.), VHF/UHF R&S ST452U(.)

Features

In the following, transmitter-specific features and benefits are listed only:

FeaturesBenefits for customer
Continuous operation
  • Convection cooling
  • Generously dimensioned heat sink- Graceful power degradation in case of adverse operating conditions
  • Automatic switching off at critical temperature
  • Increased 100 W FM UHF output with additional Power Supply IZ450
High communication link reliability
Excellent spectral purity
  • Low-noise synthesizer
  • Careful wideband design of power amplifier etc. (minimizing non-linearity product emission)
  • Harmonics filter
  • UHF Circulator Set GD430U as optional submodule for installation onto the Power Amplifier modules VD430U or VT450U. When integrated in front of harmonics filter, best efficiency is obtained. It is a broadband type, thus FH capable
  • TX/RX Filters F(.)403TR options provided for insertion into the TX and RX path and physical integration into special slots of the transmitter. They are FH capable
Interference-free operation,
even under co-site and ECCM (FH) conditions
Alternative types for each of the following modules
  • Synthesizer and
  • TX/RX diode switch (needed for SECOS even in TX mode
Future-proof and cost-effective realization
and upgrading potential, eg for later ECCM or 8.33 kHz channel spacing
Great variety of
  • basic units
  • type models
  • options
High system flexibility,
including interface adaptability to control, monitoring and antenna requirements
Designed as 19" 3HU plug-in unit
  • Front and rear loaded plug-in modules
  • Space for instant or future insertion of options
  • Swivel type design of power amplifier submodules for ideal accessibility for tests under full operation; heat sink and flexible cabling between amplifier and submodules remain connected
Economic and future-proof design, excellent serviceability
