The basic circuit can be operated at 80 kHz and is limited by the PUT capacitor combi-nation. 60 kHz is the maximum modulation fre-quency. The pulse repetition rate is a linear function of VIN, the modulating voltage. Lenses or reflectors minimizes stray light noise effects. Greater output can be obtained by using a larger capacitor, which also gives a lower operating frequency, or using a higher power output IRED such as the F5D1. Average power consumption of the transmitter circuit is less than 3 watts.
