I need a power amplifier circuit for (Ground Penetrating Radar) project, i have a Pulse generator & Crystal osc. with freq.=60Mhz and Multiplier in my project.
I need power amplifier to increasing power before transmitting it through Antenna

What are your design goals/needs for this amplifier...
Gain, output power, bandwidth, efficiency, power source, input impedance, output impedance, etc?
 
Gain for TX is 10dB and gain for RX is 20dB

That's one constraint, there are many others you need to define before you can narrow down what kind of amplifier you need. Also, mentioning receive gain means that you will either have a second antenna for receive, or will need to look at TX/RX change time, path isolation, and your receiver specs. This could mean a high-power switch at the antenna (electromechanical, PIN diode, etc), or a circulator.

I think you need to better define your overall system design. Start with a block diagram, so you can start figuring out an architecture that will save you from blowing up hardware.
