 ===== RF Output Stage ===== ===== RF Output Stage =====
 +The RF output stage, shown in the figure below, is comprised of a wideband [[adi>ADL9006]] driver amp, an [[adi>ADMV8818]] tunable bandpass filter, and finally an [[adi>HMC994APM5E]] PA. The [[adi>ADMV8818]] tunable filter  operates across a 2-18GHz frequency range for additional filtering of output spurious, and can be bypassed for operation up to 24GHz.
