See our web site for RoHS Compliance methodologies and qualifications CATV, Cable Modem & DBS Fixed Wireless & WLAN Microwave Radio & Test Equipment General Description ERA-51SM+ (RoHS compliant) is a wideband amplifier offering high dynamic range. It has repeatable per - formance from lot to lot. It is enclosed in an Micro-X package. ERA-51SM+ uses Darlington configuration and is fabricated using InGaP HBT technology. Expected MTTF is 450 years at 85C 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 Function Pin Number Description RF input pin. This pin requires the use of an external DC blocking capacitor chosen for the RF IN 1 frequency of operation. RF output and bias pin. DC voltage is present on this pin therefore a DC blocking capacitor RF-OUT and DC-IN 3 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 GND 2,4 reduce ground path inductance for best performance. Notes A.
