Specifications - Optoelectronics M1 User Manual

The M1 has the maximum amount of broad gain possible without driving the front end circuitry into hard
self oscillation. The purpose of this concept is to permit the maximum possible pick-up distance from radio
transmitters. There is no gain or sensitivity adjustment possible in the circuit. Specific sensitivities at par-
ticular frequencies are difficult to predict with precision in production units. The input sensitivity specifica-
tions below are intended to be a rough indication as to what may be expected. Defective components such
as blown amplifiers, broken or unsoldered chip resistors, capacitors and inductors will cause a drastic reduc-
tion in performance. These typical sensitivity specifications should not be relied upon for the purposes of
incoming inspection or evaluation. Contact the factory if the results obtained are significantly different than
those below. Performance on an antenna does not always relate exactly to input sensitivity as measured on
a signal generator. The purpose is to provide the best possible antenna performance regardless of sensitivi-
ty.
