Monolithic Amplifier

MAR-8A

50Ω, DC to 1000 MHz

Features

• exact footprint substitute** MAR-8 and MSA-0885

• high gain, 31.5 dB at 100 MHz, reduces component count

• high power output, +12.5 dBm typ.

• low noise

• improved stability

• protection against power supply transients

• patent pending

** See Bias resistor table; resistor values are higher than MAR-8/MSA-0885

how to replace: increase bias resistor (Rbias) by 110 ohms
benefits: • lower device voltage, 3.7V typ.
