RF2304 GENERAL PURPOSE LOW-NOISE AMPLIFIER RoHS Compliant & Pb-Free Product Package Style: SOIC-8 Features Single 2.7V to 6.0V Supply 6dBm Output Power 8dB Small Signal Gain at 900MHz 1.8dB Noise Figure at 900MHz Low DC Current Consumption of 5mA 300MHz to 2500MHz Operation GND 1 8 NC GND 2 7 VDD RF IN 3 6 RF OUT GND 4 5 GND Applications Receive or Transmit LowNoise Amplifiers FDD and TDD Communication Systems Commercial and Consumer Systems Portable Battery Powered Equipment Wireless LAN ISM Band Applications Functional Block Diagram Product Description The RF2304 is a low-noise small-signal amplifier. The device is manufactured on a low-cost Gallium Arsenide MESFET process, and has been designed for use as a gain block in high-end communication systems operating from less than 300MHz to above 2.5GHz. With +6dBm output power, it may also be used as a driver in transmitter applications, or in highly linear receivers. The device is packaged in an 8-lead plastic package and is self-contained, requiring just an inductor and blocking capacitors to operate. The +6dBm output power, combined with the 1.8dB noise figure at 900MHz allows excellent dynamic range for a variety of receive and transmit applications.

For best performance, keep traces physically short and connect immediately to ground plane. Same as pin 1. DC coupled RF input. A broadband impedance match is produced by internal shunt resistive feedback. The DC level is approximately 200mV. If a DC path exists in the connected circuitry, an external DC-blocking capacitor is required to properly maintain the DC operating point. Same as pin 1. Same as pin 1. RF output. A broadband impedance match is produced by internal shunt resistive feedback. The DC connection to the power supply is provided through an external chip inductor having greater than 150 reactance at the operating frequency. An external DC-blocking capacitor is required if the following circuitry is not DC-blocked. VDD RF OUT RF IN Bias control connection. This pin is normally connected to the power supply, but can be used to switch the amplifier on and off by switching between power supply voltage and ground. This pin sinks approximately 600A when connected to VDD, and sources less than 10A when grounded. No connection.
