ADMV4630BCPZN

ADMV4630BCPZN is a Ku band upconverter optimized for various satellite communication (SATCOM) user terminals that operate in the 14.0GHz to 14.5GHz frequency range. The ADMV4630 local oscillator (LO) signal is generated internally via the on-chip Integer N (INT) synthesizer. The internal synthesizer enables LO frequency coverage from 8.7GHz to 10.7GHz. The input intermediate frequency (IF) signals from 3GHz to 5GHz are upconverted to an RF of 14.0GHz to 14.5 GHz. The chip includes filtering to attenuate both the LO feedthrough and the unwanted lower sideband. The chip also includes a digital step attenuator at the IF input to provide up to 31dB of gain control range with 1dB steps to adjust for preceding cable losses. The transmitter output is automatically muted if the synthesizer becomes unlocked. The application includes SATCOM user terminals.
