Characteristic Description
FCA3003, FCA3103 DC to 0.1 MHz modulation: up to 94% depth
0.1 MHz to 6 MHz modulation: Signal level with lowest output
must meet sensitivity r equirements. Signal level at highest
level must not exceed maximum v oltage requirements. Within
these constraints >85% AM is acceptable.
FCA3020, FCA3120 Signal level with lowest output must meet sensitivity
requirements. Signal level at highest level must not exceed
maximum voltage requirements. Within these constraints
>90% AM is acceptable.
AM tolerance
MCA3027 MCA3040 Signal level with lowest output must meet sensitivity
requirements. Signal level at highest level must not exceed
maximum voltage requirements.
