| RF2317 0 RoHS Compliant & Pb-Free Product Typical Applications * CATV Distribution Amplifiers * Cable Modems * Broadband Gain Blocks Product Description The RF2317 is a general purpose, low-cost high-linearity 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 75 gain block. The gain flatness of better than 0.5dB from 50MHz to 1000MHz, and the high linearity, make this part ideal for cable TV applications. Other applications include IF and RF amplification in wireless voice and data communication products operating in frequency bands up to 3GHz. The device is selfcontained with 75 input and output impedances and requires only two external DC biasing elements to operate as specified. -A0.157 0.150 0.008 0.004 0.020 0.014 LINEAR CATV AMPLIFIER * Laser Diode Driver * Return Channel Amplifier * Base Stations 0.020 REF 0.393 0.386 0.034 REF 0.068 0.064 0.244 0.229 8 MAX 0 MIN 0.068 0.053 0.034 0.016 0.009 0.007 Optimum Technology Matching(R) Applied Si BJT Si Bi-CMOS InGaP/HBT GaAs HBT SiGe HBT GaN HEMT GaAs MESFET Si CMOS SiGe Bi-CMOS Package Style: CJ2BAT0 Features * DC to 3.0GHz Operation * Internally Matched Input and Output NC 1 GND 2 GND 3 RF IN 4 NC 5 GND 6 GND 7 NC 8 16 NC 15 GND 14 GND 13 RF OUT 12 NC 11 GND 10 GND 9 NC * 15dB Small Signal Gain * 4.9dB Noise Figure * +47dBm Output IP3 * Single 9V to 12V Power Supply Ordering Information RF2317 RF2317 PCBA RF2317 PCBA Linear CATV Amplifier Fully Assembled Evaluation Board - 50 Fully Assembled Evaluation Board - 75 Tel (336) 664 1233 Fax (336) 664 0454 http://www.rfmd.com Functional Block Diagram RF Micro Devices, Inc. 7628 Thorndike Road Greensboro, NC 27409, USA Rev A19 050822 3-17 RF2317 Absolute Maximum Ratings Parameter Device Current Input RF Power Output Load VSWR Ambient Operating Temperature Storage Temperature Rating 250 +18 20:1 -40 to +85 -40 to +150 Unit mA dBm C C Caution!

Ground connection. Keep traces physically short and connect immediately to ground plane for best performance. Each ground pin should have a via to the ground plane. Same as pin 2. 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. This pin is internally not connected. Same as pin 2. Same as pin 2. This pin is internally not connected. This pin is internally not connected. Same as pin 2. Same as pin 2. This pin is internally not connected. RF output and bias pin. Because DC is present on this pin, a DC blocking capacitor, suitable for the frequency of operation, should be used in most applications. For biasing, an RF choke in series with a resistor is needed. The DC voltage on this pin is typically 8.3V with a current of 150mA (for 75 board). See device voltage versus device current plot. In lower power applications the value of RC can be increased to lower the current and VD on this pin.
