ADMV8420-EVALZ，用于 ADMV8420 11 至 20 GHz 可调带通滤波器的评估套件

使用 Analog Devices 的 ADMV8420 的参考设计

设计简介

ADMV8420-EVALZ，ADMV8420 的评估套件是一款单片微波集成电路 (MMIC)、可调谐带通滤波器，具有用户可选择的通带频率。 3 dB 滤波器带宽约为 20%，20 dB 滤波器带宽约为 40%。此外，通过施加 0 至 15 V 之间的中心频率控制电压，中心频率 (fCENTER) 在 11 至 20 GHz 之间变化。该可调谐滤波器是开关滤波器组和腔体调谐滤波器的较小替代方案。 ADMV8420 采用单片设计，具有最小的颤噪效应，并在高级通信应用中提供动态可调的解决方案

说明

ADMV8420-EVALZ, Evaluation Kit for the ADMV8420 is a monolithic microwave integrated circuit (MMIC), tunable band-pass filter that features a user-selectable pass band frequency. The 3 dB filter bandwidth is approximately 20%, and the 20 dB filter bandwidth is approximately 40%. Additionally, the center frequency (fCENTER) varies between 11 to 20 GHz by applying a center frequency control voltage between 0 to 15 V. This tunable filter is a smaller alternative to switched filter banks and cavity tuned filters. The ADMV8420 has minimal microphonics due to the monolithic design and provides a dynamically adjustable solution in advanced communications applications
