Waveguide frequency mixers operate across Ka, Q, U, V, E and W bands
Designs utilize 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.
The new waveguide frequency mixers from Pasternack 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°C to +50°C. 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.
The waveguide mixers, also referred to as waveguide converters, are a key building block component of mm-wave 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.
"Pasternack’s new waveguide frequency mixers are desirable for a variety of signal conversion applications including radar, communication systems and test instrumentation," explains Tim Galla, Active Components Product Manager at Pasternack. "Our comprehensive in-stock selections of up and down converter waveguide mixers deliver low conversion loss levels across full Ka, Q, U, V, E, W bands."
