The MC-7842 and MC-7843 are GaAs hybrid integrated circuits designed to be used as the output stage in CATV cable distribution amplifier applications up to 870 MHz. The only difference between the MC-7842 and the MC-7843 is gain of about 22 dB and 24 dB respectively. With this product, NEC has made significant advancements to their initial power doubler product offering, including lower distortion, higher crash point, less variation in gain over temperature, a reduction in out of band gain at the high end, and improved ability to survive an overdrive. Like the previous products, these devices survive such hazards as surge and ESD as well as their sili-
