See our web site for RoHS Compliance methodologies and qualifications • Cellular • PCN instrumentation General Description MAR-1+ (RoHS compliant) is a wideband amplifier offering high dynamic range. It has repeatable perfor- mance from lot to lot. It is enclosed in a Micro-X package. MAR-1+ uses Darlington configuration and is fabricated using InGaP HBT technology. Expected MTTF is 15,000 years at 85°C case temperature. simplified schematic and pin description RF-OUT and DC-IN RF-OUT and DC-IN 3 RF IN 4 GND GND 2 1 RF IN GROUND FunctionPin NumberDescription RF input pin. This pin requires the use of an external DC blocking capacitor chosen RF IN 1 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 RF-OUT and DC-IN 3 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 GND 2,4 Design” to reduce ground path inductance for best performance. Notes A.
