Linear power amplifierfor 2-meter transverter delivers 10 W PEP using two Siliconix VMP1 Mospower FETs. L1 and L2 are 8 turns, and L3 and L4 are 5 turns, all close-wound with No. 20 enamelon 3-mm form. Tran-sistor requires heatsink, insulated from chassis with 0.062-in beryllium oxide insulators. Effi-ciency is about 40%. -L. Leighton, Two-Meter Transverter Using Power FETs, Ham Radio, Sept. 1976, p 10-15.
