Pasternack Mixers Operate Across 26.5 to 110 GHz
Waveguide frequency mixers offer low conversion loss performance in rugged packages
Pasternack, a US provider of RF, microwave and millimeter wave (mmwave) products, has added new mmwave waveguide frequency mixers to its range.
These are available in six down-conversion and six up-conversion models that cover full Ka, Q, U, V, E, and W bands. Designs use high performance GaAs Schottky Barrier beam lead diodes in balanced configurations that require a +13 dBm LO drive and display low levels of conversion loss.
Pasternack's new waveguide mixers, also referred to as waveguide converters, are a key building block component of mmwave receivers used to down-convert very high frequency signals to usable RF frequencies for cost effective signal processing.
They are also very useful for test and measurement applications to convert signals to frequency levels that can be measured with available equipment. Similarly, these mixers can be used to efficiently up-convert RF signals to millimeter wave frequencies for point-to-point radio and millimeter wave radar applications.
The new waveguide frequency mixers operate over RF and LO frequency bands ranging from 26.5 to 110 GHz with an IF frequency covering DC to 18 GHz. Depending on the model, conversion loss ranges from 6 to 9 dB typical with 20 dB typical RF to LO isolation. Maximum RF input power is +5 dBm and performance is specified over an operating temperature of 0 to +50degC.
Rugged gold plated package designs are thermally stable for high reliability and feature compact dimensions with integrated waveguide sizes ranging from WR-28 to WR-10.
