QTY. (20) +RoHS Compliant The +Suffix identifies RoHS Compliance. See our web site for RoHS Compliance methodologies and qualifications General Description MAR-1SM+ (RoHS compliant) is a wideband amplifier offering high dynamic range. It has repeatable performance from lot to lot. It is enclosed in a Micro-X package. MAR-1SM+ uses Darlington configuration and is fabricated using InGaP HBT technology. Expected MTBF is 14,000 years at 85°C case temperature. simplified schematic and pin description RF-OUT and DC-IN RF IN GROUND RF-OUT and DC-IN 3 4 GND GND 2 1 RF IN Function RF IN RF-OUT and DC-IN GND Pin Number 1 3 2,4 Description RF input pin. This pin requires the use of an external DC blocking capacitor chosen for the frequency of operation. RF output and bias pin. DC voltage is present on this pin; therefore a DC blocking capacitor is necessary for proper operation. An RF choke is needed to feed DC bias without loss of RF signal due to the bias connection, as shown in “Recommended Application Circuit”. Connections to ground. Use via holes as shown in “Suggested Layout for PCB Design” to reduce gr...
