The Channel to Channel Isolation varies over frequency, gain, and filter corner.
Attached are measurements done on a typical part for 3 different filter corners (144, 720 MHz and Bypass Mode ) and 3 different gain settings (0, 30, 54 dB) while keeping the output at 0 dBm.
Measurements that were taken were Channel 1 Input to Channel 2 Output, Channel 2 Input to Channel 1 Output, and Channel 1 Output to Channel 2 Output. Signal path pins that were not driven were terminated in 50 Ohms.
