RF2312 0 LINEAR GENERAL PURPOSE AMPLIFIER RoHS Compliant & Pb-Free Product Typical Applications • CATV Distribution Amplifiers • Laser Diode Driver • Cable Modems • Return Channel Amplifier • Broadband Gain Blocks • Base Stations Product Description The RF2312 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 75Ω gain block. The gain flatness of better than 0.5dB from 5MHz 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 2500MHz. The device is self-contained with 75Ω input and output impedances, and requires only two external DC biasing elements to operate as specified. -A0.160 0.152 0.200 0.192 9 GaAs HBT GaAs MESFET Si Bi-CMOS SiGe HBT Si CMOS InGaP/HBT GaN HEMT SiGe Bi-CMOS 0.010 0.004 0.050 0.248 0.232 8° MAX 0° MIN 0.059 0.057 0.0100 0.0076 0.0500 0.0164 NOTES: 1.

This pin is NOT internally DC-blocked. A DC-blocking capacitor, suitable for the frequency of operation, should be used in all applications. The device has internal feedback, and not using a DCblocking capacitor will disable the temperature compensation.The bias of the device can be controlled by this pin. Adding an optional 1kΩ resistor to ground on this pin reduces the bias level, which may be compensated for by a higher supply voltage to maintain the appropriate bias level. The net effect of this is an increased output power capability, as well as higher linearity for signals with high crest factors. DC-coupling of the input is not allowed, because this will override the internal feedback loop and cause temperature instability. Ground connection. For best performance, keep traces physically short and connect immediately to ground plane. Each ground pin should have a via to the ground plane. 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. 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 value for the resistor RC is 30Ω (0.5W) for VCC =9V and 21Ω for VCC =8V. The DC voltage on this pin is typically 6.0V with a current of 100mA. In lower power applications the value of RC can be increased to lower the current and VD on this pin.

The RC network of R2 and C3 should be kept physically as short as possible. R2 can be adjusted as required to improve the impedance matching. R6 and R7 reduce the typical gain by increasing the emitter resistance. L1 should be at least 200 Ω reactive at the lowest operating frequency. C1 and C2 should be less than 10 Ω at the lowest operating frequency. C4 and C5 improve gain flatness. 3-6 Rev C6 051025 RF2312 Application Schematic Push-Pull Standard Voltage P1 1 GND 2 3 CON3 120 Ω 120 Ω 120 Ω 120 Ω 0.1 uF V U1 F EDGE 616PT1030 1 8 2 7 3 6 4 5 RF2312 616PT1030 U2 V 1 8 2 7 3 6 4 F EDGE 5 RF2312 Rev C6 051025 3-7 RF2312 Application Schematic Push-Pull 24V P1 1 GND 2 3 CON3 120 Ω F EDGE 120 Ω U1 2400 Ω 616PT1030 120 Ω 10 nF 120 Ω 0.1 uF 10 uH 1 8 2 7 3 6 4 5 10 nF 616PT1030 F EDGE 0.1 uF RF2312 10 nF 47 nF 2400 Ω 63 nF 10 uH 120 Ω 120 Ω 120 Ω 120 Ω U2 10 nF 1 8 2 7 3 6 4 5 RF2312 3-8 Rev C6 051025 RF2312 Evaluation Board Schematic - 50Ω (Download Bill of Materials from www.rfmd.com.)
