Introduction
Noise parameter measurements are typically performed using a Vector Network Analyzer (VNA) to measure the s-parameters of an amplifier, and a Noise Figure Analyzer (NFA) to measure the noise figure or noise power of an amplifier. While traditional NFAs are commonly available up to 26.5 GHz, Many amplifier designers wish to test their amplifiers past this frequency limit. The MT7553 series of Noise Receiver Modules enable engineers to take ultra-wideband noise parameter measurements by extending the frequency limit of the NFA to 50, 75, 90 or 100 GHz.
MT7553B 10 MHz to 50 GHz Noise Receiver Modules
MT7553B 50 GHz Noise Receiver Module
The MT7553B is much more than a simple downconverter. It is the backbone of a 50 GHz noise parameter measurement system. A downconverter accepts an input signal (RF) at F1 and mixes it with local oscillator signal F2, resulting in and intermediate frequency (IF) of F1-F2, a frequency able to be directly measured by a noise figure analyzer. The Noise Receiver Module consists of a downconverter with integrated mixer and local oscillator, as well as integrated bias networks to power the device under test, integrated RF switches to switch between VNA and NPA paths, and integrated low-noise amplifier (LNA) to improve receiver noise figure. In essence, the MT7553 replaces the entire output block, or receiver module, of a noise parameter measurement system, and is designed for easy on-wafer integration.
MT7553B01 and MT7553B03 50 GHz PNA-X Noise Receiver Modules
2.4mm Connectors - Solid State - Combined VNA/NFA Port
The MT7553B01 and MT7553B03 have been tailored for Keysight Technologies' new "one-box" solution, the PNA-X. Because the Noise Parameter and S-Parameter ports on the PNA-X are one and the same, the MT7553B01 has been designed for use with the N5245A-series PNA-X with option H29 (internal 26 GHz noise receiver) while the MT7553B03 has been designed for use with the N5245Aseries PNA-X with option 029 (internal 50 GHz noise receiver). See Maury Microwave article reprint 5A-042 for the speed and accuracy benefits of using the PNA-X over traditional methods.
MT7553M Millimeter Wave Noise Receiver Modules
Millimeter Wave 50-75 GHz (WR15), 60-90 GHz (WR12) & 75-100 GHz (WR10) - Solid State
The MT7553M is designed for full millimeter wave noise parameter measurements within the TE10 waveguide band of operation. The MT7553M downconverts noise power densities from the frequency of interest to the NFA bandwidth using a double-side band swept LO technique. The MT7553M is available in configurations covering the 50-75 GHz (WR15), 60-90 GHz (WR12) and 75-100 GHz (WR10) frequency ranges.
