ACA2431 1.218 GHz High Output GaN CATV Power Doubler Amplifier PRELIMINARY DATA SHEET - Rev 1.1 FEATURES • 50 to 1218 MHz Frequency Range • +59 dBmV output power • 28 dB Gain @ 1.218 GHz • Single +24 V Supply • Operating Current = 460 mA • GaN Amplifier Technology • Halogen Free/RoHS Compliant • External current control for lower power applications APPLICATIONS • Advanced high power, high frequency HFC transmission systems 16 Pin Wide Body SOIC with Heat Slug • Output power doubler for Deep Fiber Node in CATV distribution • CATV digital edge QAM output driver PRODUCT DESCRIPTION The ACA2431 is a highly linear, high output power integrated RF amplifier designed for CATV heads ends and HFC distribution systems. The IC consists of two parallel amplifiers that are optimized for exceptionally low distortion, high output power, and high crash point in a thermally enhanced surface mount package. A GaN output stage is incorporated to minimize the operating (bias) current, thus making this an excellent choice for environmentally friendly “green” initiatives. RF Input The ACA2431 provides high gain over the 50 to 1218 MHz CATV downstream band, and is cascaded between two transmission line baluns. 1A 2A 1B 2B ACA2431 Figure 1: Block Diagram 03/2015 RF Output ACA2431 1 GND GND 16 2 2A IN 1A OUT 15 3 GND Bias 1A 14 4 1A IN 2A OUT 13 5 1B IN 2B OUT 12 6 I SET Bias 1B 11 7 2B IN 1B OUT 10 8 GND GND 9 Figure 2: Pinout Table 1: Pin Description 2 PIN NAME DESCRIPTION PIN NAME DESCRIPTION 1 GND Ground 9 GND Ground 2 2AIN Amplifier 2A Input 10 1B OUT Amplifier 1B Output 3 GND Ground 11 Bias 1B Bias for 1B Amplifier 4 1AIN Amplifier 1A Input 12 2BOUT Amplifier 2B Output and Supply 5 1B IN Amplifier 1B Input 13 2AOUT Amplifier 2A Output and Supply 6 I SET Current Adjust 14 Bias 1A Bias for 1A Amplifier 7 2BIN Amplifier 2B Input 15 1A OUT Amplifier 1A Output 8 GND Ground 16 GND Ground PRELIMINARY DATA SHEET - Rev 1.1 03/2015 ACA2431 ELECTRICAL CHARACTERISTICS Table 2: Absolute Minimum and Maximum Ratings PARAMETER MIN MAX UNIT Supply (pins 12, 13) 0 +28 VDC Current Adjust (pin 6) - +4 VDC RF Power at Inputs (pins 4, 5) - +75 dBmV Case Operating Temperature Range (TC) -40 +110 C Storage Temperature -65 +150 °C Soldering Temperature - +260 °C Soldering Time - 5.0 Sec Stresses in excess of the absolute ratings may cause permanent damage. Functional operation is not implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely affect reliability. Notes: (1)Pins 2, 4, 5 and 7 should be AC-coupled. No external DC bias should be applied. (2)Pin 6 should be AC-grounded and/or pulled to ground through a resistor for current control. (3) Pins 10, 11, 14 and 15 should have no other external bias applied.
