See our web site for RoHS Compliance methodologies and qualifications Cellular/ PCS/ 3G Base Station CATV, Cable Modem & DBS Fixed Wireless & WLAN Microwave Radio & Test Equipment Suitable for low phase noise applications General Description ERA-21SM+ (RoHS compliant) is a wideband amplifier offering high dynamic range. It has repeatable performance from lot to lot. It is enclosed in an Micro-X package. ERA-21SM+ uses Darlington con- figuration and is fabricated using InGaP HBT technology. Expected MTTF is 3,700 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 RF IN 1 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 Ap- plication Circuit. Connections to ground. Use via holes as shown in Suggested Layout for PCB Design GND 2,4 to reduce ground path inductance for best performance. Notes A.
