Do you advise a book or other source of information to teach me desig 2 stage RF PA for frequence under 30Mhz?

Any as see pic.

I know little about it, but
- I can not determine the input and output impedance of the transistor
and then I can not suggest matching networks .
In the second step I can not design the RF choke to the transistor

if anyone was able and was willing to advise,
let's imagine
In first stage amplifier we will use **broken link removed**
in second stage for example SiHP15N50E
and Gate 2 stage transistor have to ground 25Ohm resistor as load for 1 stage.
Output power 2stage is for example 50dBm.

I will clarify the query

1. Input impedance of 1 stage transistor
Is input impedance in this stage resistance R100k Ohm + reluctance of Gate capacitor IRF510 Ciss 180pF ?

And how calculate output impedance of this stage?
