Abstract: A small lightweight portable television transmitter having few components and operable with NTSC, PAL and SECAM systems. A one transistor video amplifier receives a gain controlled video signal and adjusts the d.c. level. Common mode noise rejection and sync pulse stretching is provided by a two transistor single ended output differential amplifier. The r.f. modulator combines and emitter follower and a one transistor mixer, with the r.f. applied to the collector and the modulating signals, including video and an audio modulated subcarrier, applied to the base. The transmitter has less than about 210 electrical components, weighs less than 1 kg when constructed with discrete components and substantially less when integrated into a hybrid circuit, yet provides 3 watts minimum peak power.
