Published:2009/7/7 4:47:00 Author:May | From:SeekIC

Single transistor mounted on heavy heatsink provides about 9.4-dB gain. 8-W drive at 13.5 VDC produces full output power. Series tuning inductors are printed striplines with ground plane removed beneath them; report gives designs for photomasks. Transistor will withstand 20:1 VSWR at all phase angles,-T.
