MAR-8ASM+

Surface Mount Monolithic Amplifier DC-1 GHz Product Features • Exact footprint substitute for MAR-8SM and MSA-0886a,b 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. • Internally Matched to 50 Ohms • Low noise • Improved stability • Protection against power supply transients Generic photo used for illustration purposes only MAR-8SM+ 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 performance 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 GND 4 GND 2 1 RF IN GROUND Function Pin Number Description 1 RF input pin. This pin requires the use of an external DC blocking capacitor chosen for the frequency of operation. RF-OUT and DC-IN 3 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”. GND 2,4 RF IN Connections to ground. Use via holes as shown in “Suggested Layout for PCB 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.
