ACA2420 24V, 1000 MHz, 21.5dB Gain High Output Power Doubler Line Amplifier ADVANCED PRODUCT INFORMATION - Rev 0.1 FEATURES • 21.5 dB Gain • 75 V input and output match • Characterized at +58dBmV output power • Superior gain flatness (+ 0.2dB) • Very Low Distortion • Stable with High VSWR Load Conditions • Monolithic GaAs Design for Consistent Performance Part-to-Part • Surface Mount Package Compatible with Automatic Assembly • RoHS Compliant Package APPLICATIONS S7 Package 16 Pin Wide Body SOIC with Heat Slug • CATV Line Amplifiers, Deep Fiber Nodes PRODUCT DESCRIPTION The ACA2420 is a highly linear, monolithic GaAs RF amplifier that has been developed to replace, in new designs, standard CATV hybrid amplifiers. Offered in a convenient surface mount package, the MMIC consists of two pairs of parallel amplifiers that are optimized for exceptionally low RF Input distortion. A hybrid equivalent that provides flat gain response and excellent input and output return loss over the 40 to 1000 MHz CATV downstream band is formed when one ACA2420 is cascaded between two appropriate transmission line baluns. 1A 2A 1B 2B ACA2420 Figure 1: Hybrid Application Diagram 07/2008 RF Output ACA2420 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: Pin Out Table 1: Pin Description 2 PIN NAME 1 GND 2 DESCRIPTION PIN NAME Ground 9 GND Ground 2AIN Amplifier2AInput 10 1BOUT Amplifier1BOutput 3 GND Ground 11 Bias1B 4 1AIN Amplifier1AInput 12 2BOUT Amplifier2BOutputand Supply 5 1BIN Amplifier1BInput 13 2AOUT Amplifier2AOutputand Supply 6 ISET CurrentAdjust 14 Bias1A 7 2BIN Amplifier2BInput 15 1AOUT Amplifier1AOutput 8 GND Ground 16 GND Ground ADVANCED PRODUCT INFORMATION - Rev 0.1 07/2008 DESCRIPTION Biasfor1BAmplifier Biasfor1AAmplifier ACA2420 ELECTRICAL CHARACTERISTICS Table 2: Absolute Mimimum and Maximum Ratings PARAMETER MIN MAX UNIT Supply(pins12,13) 0 +28 VDC CurrentAdjust(pin6) 0 +4 VDC RFPoweratInputs(pins4,5) - +75 dBmV -65 +150 °C SolderingTemperature - +260 °C SolderingTime - 5.0 Sec StorageTemperature 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 11 and 14 are bias feeds for input amplifiers 1A and 1B. No external DC bias should be applied. 4. Pins 10 and 15 receive DC bias directly from pins 11 and 14.
