ADL5387 & ADL5380 RF-IF isolation measurements

Question I am working up a couple of receiver designs based on the above quadrature demodulator devices. Neither data sheet provides any data on the RF-IF isolation which is a critical parameter for device selection in my case. Can you please provide plots of RF-IF isolation for both devices especially over the 2 - 120 MHz frequency range? At the minimum, can you provide the worst-case typical (if that makes sense!) figures over this frequency range? The measurement should go something like this: 1. Input to LO port = somewhere between 400 MHz and 1 GHz at 0 dBm. 2. Input to RF port = 2 to 120 MHz at ~-20 dBm. 3. Measure the direct leakage power of this input stimulus at both the I and Q outputs and report the difference between input and output power in dB over the RF input frequency range. Answer Please find attached the RF-IF isolation measurement results of both ADL5387 and ADL5380.
