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