| RF3374 0 Pb-Free Product Typical Applications * Basestation Applications * Broadband, Low-Noise Gain Blocks * IF or RF Buffer Amplifiers Product Description The RF3374 is a general purpose, low-cost RF amplifier IC. The device is manufactured on an advanced Gallium Arsenide Heterojunction Bipolar Transistor (HBT) process, and has been designed for use as an easily-cascadable 50 gain block. Applications include IF and RF amplification in wireless voice and data communication products operating in frequency bands up to 6000MHz. The device is self-contained with 50 input and output impedances and requires only two external DC-biasing elements to operate as specified. 1.04 0.80 0.50 0.30 1.60 1.40 GENERAL PURPOSE AMPLIFIER * Driver Stage for Power Amplifiers * Final PA for Low-Power Applications * High Reliability Applications 3.10 2.90 0.48 0.36 2 PL 4.60 4.40 2.60 2.40 Shaded lead is pin 1.

Note 1: All specification and characterization data has been gathered on standard FR-4 evaluation boards. These evaluation boards are not optimized for frequencies above 2.5GHz. Performance above 2.5GHz may improve if a high performance PCB is used. Note 2: The RF3374 must be operated at or below 80mA in order to achieve the thermal performance listed above. While the RF3374 may be operated at higher bias currents, 65mA is the recommended bias to ensure the highest possible reliability and electrical performance. Note 3: Because of process variations from part to part, the current resulting from a fixed bias voltage will vary. As a result, caution should be used in designing fixed voltage bias circuits to ensure the worst case bias current does not exceed 80mA over all intended operating conditions. 3050 years Power Supply 4-584 Rev A7 050310 RF3374 Pin 1 Function RF IN Description RF input pin. This pin is NOT internally DC blocked. A DC blocking capacitor, suitable for the frequency of operation, should be used in most applications. DC coupling of the input is not allowed, because this will override the internal feedback loop and cause temperature instability. Ground connection. RF output and bias pin. Biasing is accomplished with an external series resistor and choke inductor to VCC. The resistor is selected to set the DC current into this pin to a desired level. The resistor value is determined by the following equation: Interface Schematic 2 3 GND RF OUT RF OUT ( V SUPPLY - V DEVICE ) R = -----------------------------------------------------I CC Because DC is present on this pin, a DC blocking capacitor, suitable for the frequency of operation, should be used in most applications. The supply side of the bias network should also be well bypassed. Care should also be taken in the resistor selection to ensure that the current into the part never exceeds 80mA over the planned operating temperature. Ground connection.
