Description

Technical Field

[0001] This utility model relates to the field of ultra-wideband mixer technology, specifically a combined ultra-wideband mixer. Background Technology

[0002] A combined ultra-wideband mixer is a special type of frequency conversion device. Its core function is to mix the input radio frequency (RF) signal with the local oscillator (LO) signal using nonlinear elements (such as diodes and transistors) to generate an output signal containing sum frequency (RF+LO) and difference frequency (|RF-LO|) components. The target intermediate frequency (IF) signal is then extracted through filtering to achieve spectrum shifting. Compared to traditional mixers, its key feature is its ultra-wideband coverage capability (typically meeting the standard of a -10dB relative bandwidth greater than 0.20 or an absolute bandwidth exceeding 500MHz), making it suitable for the high-frequency, high-bandwidth requirements of modern communication systems.

[0003] Existing ultra-wideband mixers have limitations in terms of integration, versatility, and adaptability to different application scenarios. For example, some mixers may only be applicable to specific frequency ranges and cannot meet the needs of a wider range of frequency bands. When integrating with other test equipment or systems, some mixers may face problems such as interface incompatibility and high signal loss. Therefore, we need to propose a combined ultra-wideband mixer. Utility Model Content
