UA5M20MC Datasheet CENTELLAX 5 - 20GHz MMIC Amplifier with Integrated Bias Application The UA5M20MC MMIC Amplifier with Integrated Bias is designed for digital radio, spread spectrum, electronic warfare, and broadband communication Device Highlights systems. It can be used as a LO or mixer isolation Excellent performance 5-18GHz: amplifier, a transmit amplifier in a radio system, or as a general isolation and gain block amplifier. High, flat gain (15 0.5dB) Good return loss (15dB) Description 17.5dBm P , 20dBm P The UA5M20MC is a two-stage PHEMT high gain -1dB sat amplifier designed to be insensitive to process or Mixed-signal 3.3V operation: temperature changes. Its high isolation make it ideal Similar small-signal performance for applications requiring both gain and isolation. Good power (16.5dBm P ) The device can be operated at 5V 135mA, or 3.3V sat 108mA for integration with mixed-signal circuitry. Quick and easy to use: Features Self-biasing (5V or 3.3V supply) Integrated blocking capacitors The UA5M20MC is typically self-biased for low-cost Class-A operation, requiring only a single 5V supply Very high isolation (-36dB) both drain and both gate pads are available for 100% DC, RF, and visually tested higher-efficiency operation. The device is AC cou- Size: 920x920um (36.2x36.2mil) pled with integrated blocking capacitors.
