<Text 680 190 12 #ff0000 0 "Broad-band UHF transformerless frequency doubler using a bipolar transistor as a voltage/phase divider\nfollowed by a pair of bipolar Class "B" amplifiers combined to produce second harmonic of the input. Careful\nbalance is required to suppress the fundamental and third harmonic below -20 dBC. The 0.1 uF capacitor\nbypasses R.F. plus the A.M. noise contribution of the 1 Meg resistor. With high Ft transistors, this circuit\nshould be effective from low VHF to high UHF frequencies.">
