ERA-3+ is a surface-mount monolithic microwave integrated circuit amplifier designed for DC to 3 GHz applications with 50-ohm impedance matching. It is packaged in a Micro-X case style VV105 and operates from a single +3.0 to +3.4 V supply at 35 mA bias current. The device is unconditionally stable, transient protected, and fabricated using InGaP HBT technology with a Darlington configuration. It provides a typical gain of 16.4 dB at 3 GHz, an output P1dB of 10.5 dBm, and an output IP3 of +24 dBm at 1 GHz. Thermal resistance is 186 °C/W, and expected MTTF is 9100 years at 85°C case temperature. Operating temperature range is -45°C to +85°C. The part is RoHS compliant, moisture sensitive level 1, and rated Class 1A for HBM ESD.
ERA-3+ (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. ERA-3+ uses Darlington configuration and is fabricated using InGaP HBT technology. Expected MTTF is 9100 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 GROUND RF-IN Function Pin Number Description RF-IN 1 RF input pin. This pin requires the use of an external DC blocking capacitor chosen 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 RF-OUT and DC-IN 3 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 reduce ground path GND 2,4 inductance for best performance. REV. Q ECO-024740 ERA-3+ MCL NY 250304 www.minicircuits.com
