The waveguide, along with the coaxial line, is one of the most important transmission media in any modern RF, microwave and millimeter-wave component, and sub-assembly and system. Due to its metal tubing configuration, the waveguide tends to be heavy and bulky, especially in low microwave frequencies. However, it is always a preferred transmission means …
Many customers will question SAGE Millimeter’s waveguide to coax adapter return loss performance. They will mention that their measured return loss is lower than what is on the provided datasheets or in the specifications provided in their quotes. SAGE Millimeter has noticed that these same customers often test return loss by using the “back to … Continue reading Why is There a 6 dB Correction on Measured Waveguide to Coax Adapter Return Loss Using a Back to Back Connection?
Noise figure is an important parameter in many RF applications. Per its definition, Noise Figure (NF) is a measurement of the degradation of the signal-to-noise ratio (SNR) which is caused by components in a signal path. It is a number by which the performance of an amplifier or a radio receiver can be specified. The lower the values, the … Continue reading How to Use the Spectrum Analyzer and a Noise Source to Measure Noise Figure
SAGE Millimeter offers Doppler Radar Target Simulators for Radar manufacturers and developers to test and evaluate their Radar systems’ performance in an economic way by replacing expensive and time-consuming field tests. The standard models are offered to cover common radar frequency bands of 24.125 GHz, 35 GHz, 77 GHz, 79 GHz and 94 GHz with … Continue reading Doppler Radar Target Simulators
The industry widely used Keysight Noise Figure Analyzer (NFA) N8975A can provide accurate measurement of both gain and noise figure up to 26.5 GHz. SAGE Millimeter’s STG series Noise Figure and Gain Analyzer Extenders can extend the measurement up to 170 GHz while preserving the functionality and features that Keysight standard models offer. The model … Continue reading Extend the Keysight N8975A Noise Figure Meter to Millimeterwave
