ERA-3+ DC-3GHz SMD MMIC RF Amplifier Mini-Circuits

The ERA-3+ is a wideband MMIC / monolithic RF amplifier from Mini-Circuits, designed for applications requiring a compact, stable gain stage with good radio frequency performance.

With an operating range of DC to 3GHz, typical gain of 16.4dB, 2.9dB noise figure, 10.5dBm P1dB compression point and 24dBm OIP3, this component is suitable for reception circuits, signal distribution, CATV, communication systems, test equipment, RF instrumentation and amateur radio projects.

The ERA-3+ uses GaAs InGaP / InGaP HBT technology and offers repeatable performance from lot to lot, making it a practical solution for RF gain stages on compact boards. The Micro-X package and SMD/SMT mounting allow integration into high-frequency printed circuit boards.

This component requires correct biasing, including DC blocking capacitors and an RF choke / suitable bias circuit, according to the manufacturer’s datasheet.
