I just selected this part for a project but noticed that it is not recommended for new designs, does anyone know what the recommended replacement part is?
I called AD UK to ask but was unable to get through to anyone.

Hi Jim,
Your total voltage gain of ~100 corresponds to 40 dB so, each amp in your cascade must provide 20 dB gain.
For pulses of 5 mV (I'm assuming peak) the second amp in your cascade will need to capable of Pout~=+4 dBm. The only part under RF & Microwave recommended for new designs that I see coming close to meeting this requirement is the AD8353. It's a 1 MHz - 2.7 GHz gain block, internally matched, with typical gain=+20 dB and typical OP1dB=+9.1 dBm. Here is a link to the product page:
