SAGE Millimeter takes pride in the appearance of our products, but our design philosophy is rooted in our understanding of our customers and the technology. One year ago, SAGE decided to implement the anti-cocking variation of the MIL Spec flanges across our WR-22 and above product lines while also adding sandblasted finishing to our products. … Continue reading Benefits of Anti-Cocking and Sandblasting for RF Performance
Calibration is an essential step in any RF test and measurement procedure. By calibrating our measurement setup with known standards, we can reduce measurement uncertainty. For millimeterwave testing, SAGE Millimeter provides calibration kits that include precision machined shorts, open and loads accompanied by a set of in-series adapters with their respective connector type, see Fig … Continue reading RF Calibration Kit, Number of Mating Cycles and Proper Maintenance
The waveguide sections offered by SAGE Millimeter cover the frequency range of 8.2 to 325 GHz. These sections include waveguide straights, bends, twists, mode transitions and flange adapters. The waveguide sections are designed for full-band operations from X-band to WR-03. Other lower frequency waveguides may be available upon request. Standard waveguides offered by SAGE Millimeter … Continue reading Custom Waveguide Straights, Bends, Twists, and Flanges
SAGE Millimeter offers complete balanced mixer and upconverter solutions under the product series of SFB and SFU based on GaAs Schottky beam-lead diode and balanced circuit configuration to offer the superior RF performance. For instance, the W Band balanced mixer with model SFB-10-N1 shown in Figure 1, supports the full waveguide band operation for both … Continue reading Coaxial Low Pass Filters to Improve SFB and SFU LO to IF Port Isolation
SAGE Millimeter will become Eravant in March 2020, a change that renews our commitment to serve, first and foremost, the RF engineer. Rebranding as Eravant represents our promise to continue investing in our customers and our team members. And as our company transitions to the new brand, we trust that your experience with us will continue to set the standard for all supplier partnerships.
Historically, limited CW power was available in the millimeterwave frequency range, especially in the higher frequency bands, Ka-band and above. Therefore, power handling was not a major concern for most customers, except in the case of certain dedicated high-power applications or programs in which special attention was required. As semiconductor advancement and applications of such … Continue reading Power Handling of Waveguide Power Combiner, Directional Coupler, Crossguide Coupler and Waveguide to Coax Adapter
Waveguides are some of the most important transmission lines used in microwave applications, especially in millimeter-wave systems, due to its low loss and high-power handling characteristics. However, the waveguide has a defined operating bandwidth due to its inherent structural limitations. For example, the standard operating frequency of a WR-10 rectangular waveguide is 75 to 110 … Continue reading Many SAGE Millimeter Products have Wider than Standard Waveguide Operating Frequency Range
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
