Frequency extension from 220 GHz to 330 GHz for signal generation

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

Features & benefits

Full H-Band support

The 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 with a 30 GHz passband each, support flexible operation 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 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.

Superior signal quality

The superior signal quality, even at sub-THz frequencies, can be achieved by combining high-performance IF generation and analysis with the unique performance of R&S®FC330 frequency converters.

**EVM measurement of a single-carrier signal** - 16QAM modulation and 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 frequency range from 220 GHz to 330 GHz. It can be directly powered from the R&S®FC330 and provides a typical gain of 15 dB, delivering signals with up to +8 dBm output power (measured at saturation). Due to its low noise figure, the amplifier is suitable for the transmit (TX) and receive (RX) directions.
