DESCRIPTION
The MC-7842 and MC-7843 are GaAs hybrid integrated cir-
cuits designed to be used as the output stage in CATV cable
distribution amplifier applications up to 870 MH
z.
The only dif-
ference 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 dou-
bler 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 sur-
vive an overdrive. Like the previous products, these devices
survive such hazards as surge and ESD as well as their sili-
con competitors, but deliver superior performance with low
DC current required. All devices are assembled and tested
using fully automated equipment to maximize consistency in
part to part performance, and reliability is assured by NEC's
stringent quality and process control procedures. Both parts
come in industry compatible hybrid packages.
