Converters Simplify Amplifier Measurements In E/W Bands

Featuring electronically-adjustable output power, the ZVA-Z90E and ZVA-Z110E millimeter-wave converters allow users to analyze the power-dependent behavior of amplifiers and mixers quickly and accurately. They offer frequency ranges of 60 GHz to 90 GHz and 75 GHz to 110 GHz, respectively. The ZVA-Z90E for the E band and the ZVA-Z110E for the W band specify a dynamic range of typically greater than 110 dB and their output levels are adjustable electronically in connection with a power calibrator. Additionally, both instruments allow true differential four-port measurements up to 110 GHz, allegedly unique in this frequency range.
