ProStick + , external amp + filter combination?

After some research I found out what chips I actually have:
First stage is Qovo’s TQP3M9008. At 1000GHz it has a NF of 1.1dB and OIP3 of 37.6 dBm.

The TQP3M9008 is a cascadable, high linearity gain block amplifier in a low-cost surface-mount package. At 1.9 GHz, the amplifier typically provides 20.6 dB gain, +36 dBm OIP3, and 1.3 dB Noise Figure while only drawing 85 mA current.
The amplifier is internally matched using a high performance E-pHEMT process and only requires an external RF choke and blocking/bypass capacitors for operation from a single +5 V supply.
The TQP3M9008 covers the 0.05 – 4 GHz frequency band and is targeted for wireless infrastructure or other applications requiring high linearity and/or low noise figure.
