Waveguide mixers boast conversion loss performance in compact packages

Pasternack adds new millimeter wave (mm-wave) waveguide frequency mixers available in six down-conversion and six up-conversion models that cover full Ka, Q, U, V, E, and W bands. Designs utilise 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 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. 

The new waveguide frequency mixers from Pasternack operate over RF and LO frequency bands ranging from 26.5 to 110GHz with an IF frequency covering DC to 18GHz. Depending on the model, conversion loss ranges from 6 to 9dB typical with 20dB typical RF to LO isolation. Maximum RF input power is +5dBm and performance is specified over an operating temperature of 0 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.

“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, 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.”
