High Frequency Amplifiers
A variety of high frequency circuits with features ranging
from low cost simplicity to multifunction versatility marks
Motorola’s line of integrated amplifiers. Devices described
here are intended for industrial and communications
applications. For devices especially dedicated to consumer
products, i.e., TV and entertainment radio. (See the
Consumer Electronics Circuits section.)
Amplifiers. These parts are recommended for applications
up through 70 MHz. The best high frequency performance
may be obtained by using the physically smaller SOIC
version (shorter leads) – MC1350D. There are currently no
other RF ICs like these, because other manufacturers have
dropped their copies. Applications include variable gain
video and instrumentation amplifiers, IF (Intermediate
Frequency) amplifiers for radio and TV receivers, and
transmitter power output control. Many uses will be found in
medical instrumentation, remote monitoring, video/graphics
processing, and a variety of communications equipment.
The family of parts using the same basic die (identical circuit
with slightly different test parameters) is listed in the
following table.
