Introduction

The ADCA3990 is a power doubler hybrid module packaged in the industry-standard SOT115J. The device achieves extremely high RF output, up to 76.8 dBmV composite power or 67 dBmV virtual level, by using advanced circuit design techniques, such as gallium arsenide (GaAs) pseudomorphic high electron mobility transistor (pHEMT) die and gallium nitride (GaN) HEMT die. The dc current and supply voltage can be adjusted externally for optimum distortion performance vs. power consumption over a range of output levels.

Features

• High RF output: 76.8 dBmV total composite power or 67 dBmV virtual level
• High gain of 24.5 dB at 1218 MHz
• Very low distortion CTB and CSO: ≤ -82 dBc typical × MOD = -74 dBc typical CIN = 62 dB typical
• Low noise figure: 3 dB at 45 MHz, 4 dB at 1218 MHz
• Unconditionally stable
• Transient and surge protection
• VCC range from 24 V to 34 V
• Configurable current from 400 mA to 550 mA maximum
• Industry-standard, 8-pin SOT115J module package

Applications

• 45 MHz to 1218 MHz community access television (CATV) infrastructure amplifier systems
• Remote PHY (physical layer) and fiber deep nodes
• DOCSIS 3.1 compliant
