Frequency Multipliers Capable to 110GHz

Rohde & Schwarz is extending its frequency range for microwave signal generators to 110GHz with the release of three new frequency multipliers. The latest models in the R&S SMZ family are the first on the market to offer users the choice of either mechanically or electronically controlled built-in attenuator options. Rohde & Schwarz designed the multipliers as the perfect complement to the R&S SMF100A microwave signal generator. In addition to controlling the R&S SMZ frequency multipliers, the R&S SMF100A also automatically monitors and corrects frequency and level values. Users from the automotive sector, research institutions and the aerospace and defense industry no longer have to perform time-consuming and error-prone correction measurements using a level detector or power sensor.

From the development of parking assistance systems to the use of radar interferometry to scan the earth's surface – all applications with frequencies up to 110GHz – even high-end signal generators quickly hit their limits. This is why users have to supplement their generator with a frequency multiplier. Up until now, if the level also needed to be adjustable (essential for LO applications, for example), an external attenuator was required and the entire setup had to be calibrated.

Requiring no external attenuator, the new R&S SMZ family from Rohde & Schwarz substantially simplifies this complex test setup. Users have the option of selecting either a mechanically or electronically controlled built-in attenuator for their R&S SMZ model. The electronically controlled attenuator offers a dynamic range of 15dB, the mechanically controlled attenuator a dynamic range of 25dB.

The R&S SMZ family is the ideal complement for the R&S SMF100A microwave signal generator from Rohde & Schwarz. This combined solution simplifies test setup and test execution: the multipliers can be controlled by the generator via the USB interface so that the devices operate as a unit. They can also be remote-controlled over the R&S SMF100A's GPIB, LAN or USB interface. All settings, such as output level and output frequency are made on the R&S SMF100A. The generator receives all the data it needs from the connected R&S SMZ, in particular the precalibrated frequency response, via USB. This allows the R&S SMF100A to make automatic corrections, ensuring that the frequency and level values at the R&S SMZ output are the same as those set on the R&S SMF100A. Conventional test setups normally involved time-consuming and error-prone level measurements using a level detector or power sensor. The Rohde & Schwarz solution eliminates the need for these measurements.

The frequency multiplier family includes three models, the R&S SMZ75 (50GHz to 75GHz), the R&S SMZ90 (60GHz to 90GHz) and the R&S SMZ110 (75GHz to 110GHz).
