VU2EVQ HF ലീനിയർ ആംപ്ലിഫൈർ ബോർഡ് ഒന്ന് പരിചയപ്പെടാം

VU2EVQ Linear HF Linear Amplifier is useful in combination with uBITX QRP radio. Will give about 100W output on 40m and lower bands. About 40W output expected on 20m. Not recommended for higher bands as the high input capacitance of the final MOSFETs IRFP150 makes them ineffective at higher bands. VU2GTX has successfully combined two boards to get output of about 200W on 40m, with good on air signals. All components are locally available. Needs change of Low Pass Filter for different bands. Can work on 80m with different LPF.
