Product Description
The RF2044A 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.

NOTES:
Note 1: The RF2044A must be operated at or below 65mA in order to achieve the thermal performance stated above. Operating at 65mA will ensure the best possible combination of reliability and electrical performance.
Note 2: 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 65mA over all intended operating condi-
tions.
