HI
It is for communication applications, I am looking for a very low distortion, high linearity, super gain and phase flatness across the DC to 1Ghz bandwidth, and minimum gain and phase mismatch between the two channels (I and Q) (Maximum phase mis-match of 0.5 degrees from DC to 1Ghz and gain mismatch of 0.1 dB or lower across the entire broadband).
On the programmable gain (any range is O.K.) Ideal range will be from 0 to 6dB but even if it is high than that, we can put fixed resistor attenuators after the amplifier to reduce the gain.
I found the LMH6882 part, but it has a higher phase mismatch (1.5 degrees even at 100Mhz test frequency) between the two channels.
Could someone recommend a suitable part. I didn't find anything in the RF/IF section.
