Surface Mount Monolithic Ampliefi r DC-1 GHz Product Features a,b Exact footprint substitute for MAR-8SM and MSA-0886 Benefits: lower device voltage, 3.7 typ. lower power dissipation in the MMIC may eliminate need for choke (RFC) High gain, 31.5 dB at 0.1GHz, reduces component count High power output, +12.5 dBm typ. Generic photo used for illustration purposes only Internally Matched to 50 Ohms Low noise MAR-8SM+ Improved stability Protection against power supply transients CASE STYLE: WW107 +RoHS Compliant Typical Applications The +Suffix identifies RoHS Compliance. See our web site for RoHS Compliance methodologies and qualifications Cellular PCN instrumentation General Description MAR-8ASM+ (RoHS compliant) is a wideband amplifier offering high dynamic range. It has repeatable per - formance from lot to lot. It is enclosed in a Micro-X package. MAR-8ASM+ uses Darlington configuration and is fabricated using InGaP HBT technology. 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 Function Pin Number Description 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. Suitability for model replacement within a particular system must be determined by and is solely the responsibility of the customer based on, among other things, electrical performance criteria, stimulus conditions, application, compatibility with other components and environmental conditions and stresses. b.
