Key facts

  • Full H band support from 220 GHz to 330 GHz
  • Ultra-wide IF bandwidth up to 35 GHz
  • Low conversion loss thanks to the integrated IF amplifier
  • Superior signal quality
  • High-performance external H band amplifier

Frequency extension from 220 GHz to 330 GHz for signal analysis

R&S®FC330ST and R&S®FC330SR frequency converters are designed for upconversion and downconversion of intermediate frequency (IF) signals to and from the 220 GHz to 330 GHz RF frequency range. A high-performance mixer with low conversion loss ensures precise measurements, while the integrated IF amplifier enhances sensitivity and signal performance. R&S®FC330 frequency converters support a wide IF range up to 35 GHz for transmitting and receiving ultrawideband signals.
The optional R&S®FC330-Z50 external amplifier has a low noise figure and can boost transmitter output power or act as a low-noise amplifier to improve the receiver sensitivity. 

Features & benefits

Full H band support


 

R&S®FC330 frequency converters for upconversion and downconversion have seamless frequency coverage from 220 GHz to 330 GHz with a WR3.4 waveguide RF connector in line with the WR3 EIA standard. A set of five external bandpass filters, each with a 30 GHz passband, support flexible operations and minimize unwanted signals. These filters help selectively eliminate sideband and local oscillator signals for top performance across the entire frequency range.

Ultra-wide bandwidth up to 35 GHz

The IF frequency range of the R&S®FC330 from 1 GHz to 35 GHz enables the transmission of wideband  signals and provides the user a wide range of options for the best possible IF/LO combination. Each  frequency converter is characterized in the factory and comes with measurement and alignment data stored on a USB flash drive. The flexible customization allows precise system control to generate a specific RF frequency and is an ideal solution for various applications.

EVM measurement of a single-carrier signal

16QAM modulation with 4 GHz symbol rate at 286.5 GHz carrier frequency; devices: R&S®SFI100A, R&S®SMA100B, R&S®FC330ST/SR and R&S®FSW43.

High-performance external amplifier

The R&S®FC330-Z50 external amplifier operates within the 220 GHz to 330 GHz frequency range. The amplifier can be directly powered from the R&S®FC330 and typically has a gain of 15 dB, delivering signals with up to +8 dBm output power (measured at saturation). The low noise figure means the amplifier works in the transmit (TX) and receive (RX) directions.
