It is suitable for use in many communications receivers, performing quadrature demodulation directly to baseband frequencies. The input frequency range is 800 MH- to 2.7 GHz. The outputs can be connected directly to popular A-to-D converters such as the AD9201 and AD9283. The RF input signal goes th.
