RF2306 4 Typical Applications * Broadband, Low Noise Gain Blocks * IF or RF Buffer Amplifiers * Driver Stage for Power Amplifiers * Final PA for Low Power Applications * Portable Battery Powered Equipment * Broadband Test Equipment GENERAL PURPOSE AMPLIFIER Product Description The RF2306 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 2000MHz. The device is self-contained with 50 input and output impedances and requires only two external DC biasing elements to operate as specified. .156 .152 .017 1 .195 .191 .050 .240 .232 .056 .052 .004 MIN 4 GENERAL PURPOSE AMPLIFIERS 5 .022 .018 .008 Optimum Technology Matching(R) Applied Si BJT Si Bi-CMOS u Package Style: SOP-8 GaAs HBT SiGe HBT GaAs MESFET Si CMOS Features * DC to 2000MHz Operation * Internally matched Input and Output * 20dB Small Signal Gain * 3.5dB Noise Figure * 10mW Linear Output Power * Single Positive Power Supply RF IN 1 GND 2 GND 3 GND 4 8 RF OUT 7 GND 6 GND 5 GND Ordering Information RF2306 RF2306 PCBA General Purpose Amplifier Fully Assembled Evaluation Board Functional Block Diagram RF Micro Devices, Inc. 7625 Thorndike Road Greensboro, NC 27409, USA Tel (336) 664 1233 Fax (336) 664 0454 http://www.rfmd.com Rev B2 000228 4-63 RF2306 Absolute Maximum Ratings Parameter Supply Current Input RF Power Operating Ambient Temperature Storage Temperature Rating 65 +10 -40 to +85 -40 to +150 Unit mA dBm C C Caution!

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. Same as pin 2. Same as pin 2. Same as pin 2. Same as pin 2. Same as pin 2. 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. At room temperature, this pin will bias itself to 3.7V as long as the current is held between 20mA and 65mA. Thus the resistor value is determined by the following equation: Interface Schematic 2 3 4 5 6 7 8 GND GND GND GND GND GND RF OUT 4 GENERAL PURPOSE AMPLIFIERS RF OUT ( V SUPPLY - 3.7 ) R = --------------------------------------I CC Care should also be taken in the resistor selection to ensure that the current into the part never exceeds 65 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 3.7V is available. 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.
