Hello all i am currently working on an rf serial communications software. I am using a serial transceiver from sure electronics. Is there anyway that i can amplify the sending power of this unit.

Thanks for any help
 

The US Hittite company has a large selection of amplifier ICs.
 

Using amplifiers is possible but it adds to interference. Why don't you try to use an antenna?
The low-power systems like yours have only short whip or dielectric antennas on transmitter and receiver. If you try a small Yagi like that used for UHF TV, you could direct the RF power where your receiver stands, and limit interference, too.
If your devices have RF connectors, use a coaxial cable to connect the antenna(s). Otherwise, use UHF baluns delivered with the antennas. For your UHF range, the baluns are also easy to make; check ARRL Radio Amateurs Handbook or ARRL Antenna Handbook for details.
 
hey thanks for the help the UHF antenna got me about an extra 100m of range

thanks again!
