F1280中文资料Dual VGA 0.001MHz to 1200MHz数据手册Renesas规格书

描述 Description

The F1280 is a highly integrated 0.001MHz to 1200MHz dual VVA+VGA with integrated RMS detectors. The two independently controlled VVA+VGAs each provide 24dB of gain range with four different selectable gain ranges. The VGA gain ranges and switchable VGA2 inputs are controlled through an SPI interface with a 10MHz maximum clock operating frequency.
