NEC's MC-7847-KC is a GaAs Multi-Chip Modules designed
for use as output stages in CATV applications up to 870 MHz.
This is a high gain device offering 25 dB minimum gain at
870 MHz. Because this unit is a GaAs device it has low distortion, low noise figure, and low return loss across the entire
frequency band.
The MC-7847-KC is similar to NEC's standard push-pull
devices, but the higher current allows for better distortion
performance, especially X-mod.
Like the previous generation of products, these devices survive such hazards as surge and ESD as well as their silicon
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. These parts come in
industry compatible hybrid packages.

NOTES ON CORRECT USE
RECOMMENDED SOLDERING CONDITIONS
1. The space between PC board and root of the lead should be kept
more than 1 mm to prevent undesired stress on the lead and also
should be kept less than 4 mm to prevent undesired parasitic inductance.
This product should be soldered in the following recommended
conditions. Other soldering methods and conditions than the recommended conditions are to be consulted with our sales representatives.
Recommended space is 2.0 to 3.0 mm typical.
2.Recommended torque strength of the screw is 59 to 78 Ncm.
3.Form the ground pattern as wide as possible to minimize ground impedance. (to prevent undesired oscillation)
All the ground pins must be connected together with wide ground pattern to decrease impedance difference.
