Thanks, I appreciate the information. The FM Broadcast station, that I do engineering, just purchased a new to the market Harris 10 KW transmitter, that just arrived today. Installation the next few weeks. I took special notice of the hot pluggable PA transistor amplifier modules using this transistor. It gets 70% efficiency. With stands very high VSWR ....... 73 Bruce-K1FZ
Tom, I did not find any linear specs also, but did find a blurb saying it was quite linear up to a KW. Think will try a 900 Watt amp first, time permitting. Thank you for your research information. Jacques, FB working with Freescale the manufacturer.. Looking like the device over drives at about 1 KW producing high harmonics, the third being trouble some. Thank you for your information. Although they do not (or did not) publish IMD data, the single device I tried was acceptable at 800-900 watts PEP for SSB. They are a bit better than 4 x MRF150 in power, but still very similar. I'd say with correct heatsinking and airflow, you could make a good 800-watt plus linear amplifier from one. (From Tom W8JI) with conventional output matching networks the third harmonic distortion is extremely high around -7 to -8 dB ( second harmonic is OK because of the push pull configuration of the PA) Jacques F6BKI now retired but spend my working life with TRW , MOTOROLA and FREESCALE RF semiconductors John N4NU Thank you for your email. That old linear must have been fun. _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
