10 GHz Power Amplifier Alternatives

>>>under construction<<<
How much power do you really need to make 10 GHz contacts? 

This depends on many factors:

• The gain of your antenna and your aiming accuracy (both azimuth and elevation)
• Transmission line losses (cable, connectors and relays)
• The mode that you're using (e.g., CW, SSB, Digital, FM, etc.)
• Your receive filtering ability
• Your frequency accuracy and stability
• Atmospheric conditions
• Local terrain
• Distant obstructions
• Other stations capabilities 
• The effectiveness of your liaison method 
• Operator proficiency
• QRM (yes, this can be a factor even on 10 GHz)
• Luck!

However, many contacts can be made with an entry level station using only the transverter output and/or up to a 1 Watt amplifier as the effective radiated power can be up to 1 KW ERP (with a 30dB gain DSS dish antenna).
