  • Measuring Frequency Conversion Devices
    to the 372/300 series. The mixer, a typical frequency conversion device, will be used as the DUT. However, everything covered is also valid for other frequency conversion devices such as up or down converters, multipliers, and dividers. The measurements that will be discussed are the following
  • Mixer VNA Measurements Application Note
    Frequency translated devices are key components of any communication system, whether they are up-converters, down-converters or basic mixers. Since their input and output frequencies are different, they require special features and setups for Vector Network Analyzer (VNA) measurements
  • Schottky Mixer Feature High Dynamic Range
    of the mixer. The signal for the RF port of the mixer is typically derived from a low noise amplifier (LNA) which ultimately comes from an antenna. The resulting intermediate frequency (IF) produced from mixing the two signals is then processed or possibly down converted again.
  • Impedance Matching Techniques for Mixers and Detectors - App Note (.pdf)
    to know the admittance of the diode in the frequency band of interest. As an example, the Agilent Technologies 5082-2709 mixer diode will be matched from 8 GHz to 12 GHz. A common local oscillator power level is one milliwatt, but it is not useful to measure the diode admittance at this level
  • Schottky Diodes
    Schottky diodes have been. used for several decades. as the key elements in frequency. mixer and RF power. detector circuits. In 1938 Walter. Schottky, the son of German. mathematician Friedrich. Schottky, explained the manner. in which a junction comprised. of specific combinations of metals
  • | Electronics Industry News for EEs & Engineering Managers
    . here today announced three new mixer chips, based on a silicon germanium (SiGe) process technology. The SMDI STM-1116, STM-2116 and SRM-3116 active transmit mixers are geared for the 800-MHz to 2.5-GHz frequency bands. The devices include on-chip radio-frequency (RF), intermediate-frequency
  • Technical Note - The Basis of Spectrum Analyzers
    What is a Spectrum Analyzer? A measuring instrument that displays an electrical signal according to its frequency. When the signal and local oscillator are added at the mixer input, the suitable input level is the distortion level specification that doesn't influence the measurement. The level
  • ECCOSORB MCS/SS6M Quells Oscillations in Spectrum Analyzer
    caused by very poor rejection of the local oscillator carrier after the mixer stage. This in turn caused components to cross-talk (by wave guide phenomenon) within the aluminum housing. Since the input frequency range of LO1 is 2.1 to 3.6 GHz and LO2 is fixed at 2 GHz, ECCOSORB (R) MCS/SS6M
