Phase shift a sinus RF signal in the range between 150Mhz and 450Mhz?

Question In my application I need to phase-shift a sinus RF signal in the range between 150MHz and 450MHz, with an accuracy of 1degree. Can you recommend any device? Answer It sounds that you are looking for vector modulator, which allows amplitude/phase shifting. Please refer to below link for vector modulator and refer attached file for quadrature modulator: http://www.analog.com/en/products/rf-microwave/phase-shifters-vector-modulators/ vector-modulators.html However, the ADL5390 seems like the most suitable option for the frequency range specified.

ADL5390 Low-End Input Frequency Limit

Question: What limits the low end frequency limit of 20 MHz on ADL5390? Is it internal ac-coupling? Answer: Yes, there is AC coupling on the output buffers.
