RF2043 4 GENERAL PURPOSE AMPLIFIER Typical Applications • Broadband, Low Noise Gain Blocks • Final PA for Low Power Applications • IF or RF Buffer Amplifiers • High Reliability Applications • Driver Stage for Power Amplifiers • Broadband Test Equipment Product Description The RF2043 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 50Ω 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 50Ω input and output impedances and requires only two external DC biasing elements to operate as specified. With a goal of enhanced reliability, the extremely small Micro-X ceramic package offers significantly lower thermal resistance than similar size plastic packages.

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. Keep traces physically short and connect immediately to ground plane for best performance. 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: ( V SUPPLY – V DEVICE ) R = -------------------------------------------------------I CC 4 GND RF OUT 4 RF IN GENERAL PURPOSE AMPLIFIERS Pin 1 Care should also be taken in the resistor selection to ensure that the current into the part never exceeds 120 mA over the planned operating temperature. This means that a resistor between the supply and this pin is always required, even if a supply near 5.5V is available, to provide DC feedback to prevent thermal runaway. 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. Same as pin 2.
