Product details
Overview
CGD1042HI,112 from NXP Semiconductors is a GaAs-based hybrid amplifier module in SOT115J package, designed as a high-output-power RF doubler for CATV distribution systems. It delivers 22.7 dB typical power gain at 1003 MHz, operates at 24 V DC supply, draws 450 mA typical total current, and supports 40–1003 MHz bandwidth with 75 Ω input/output impedance - enabling broadband signal amplification in headend and node applications.
For engineers reviewing the CGD1042HI,112 datasheet, CGD1042HI,112 pinout, CGD1042HI,112 application, or CGD1042HI,112 equivalent, key selection criteria include its 22.7 dB gain flatness (±0.5 dB), −75 dBc composite triple beat (CTB) at 1003 MHz, 5.5 dB noise figure at 1 GHz, integrated ring wave surge protection, and unconditionally stable operation across full CATV band.
Technical Context
The CGD1042HI,112 employs heterojunction FET (HFET) GaAs dies in a thermally optimized hybrid construction, delivering high linearity and low distortion over temperature via built-in gain compensation. Its unconditionally stable design eliminates external stabilization networks, while integrated ESD protection (2000 V HBM) and ring wave surge immunity support rugged deployment in outdoor plant environments.
Operating at 24 V DC with 450 mA typical current draw, the device maintains 75 Ω input/output matching across 40–1003 MHz, achieving >16 dB return loss up to 1003 MHz and <1 dB flatness - critical for multi-channel digital and analog video signal integrity in 79 NTSC + 75 digital channel configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CGD1040HI,112 | Lower 19.5 dB gain at 1003 MHz; identical SOT115J package and pinout | Targeted for lower-gain distribution stages where CTB margin allows reduced output power | Select when system-level gain budget permits 2.2 dB lower output and lower thermal dissipation is prioritized |
| CGD1044HI,112 | Higher 24.5 dB gain at 1003 MHz; same footprint but requires tighter thermal management | Used in headend final-stage amplifiers requiring maximum output drive capability | Choose when >23 dB gain is mandatory and PCB layout accommodates higher power dissipation |
Compared with CGD1042HI,112, the CGD1040HI,112 offers lower gain and thermal load for mid-span use, while the CGD1044HI,112 provides higher output at the cost of increased current draw and thermal sensitivity - all three share identical pinout and 75 Ω interface for drop-in evaluation.

FAQ
What is the operating supply voltage range for the CGD1042HI,112?
The CGD1042HI,112 operates at a nominal 24 V DC supply, with an absolute maximum rating of 30 V DC per IEC 60134 limiting values. It draws 440–460 mA typical total current at 24 V, and its gain compensation circuitry maintains stable RF performance across this regulated supply range without external regulation beyond standard filtering.
Does the CGD1042HI,112 require external biasing components?
No, the CGD1042HI,112 integrates all necessary biasing circuitry for its GaAs HFET dies. It only requires a single 24 V DC supply on pin 5 (+VB), proper RF input/output matching (75 Ω), and DC grounding on pins 2, 3, 7, and 8. No external gate or drain bias resistors, capacitors, or feedback networks are needed due to its unconditionally stable architecture.
What is the thermal management requirement for the CGD1042HI,112?
The CGD1042HI,112 uses an aluminum flange in SOT115J package designed for direct mechanical and thermal attachment to a heatsink. Its maximum mounting base temperature is +100 °C, and it dissipates ~10.8 W (24 V × 450 mA). To maintain reliability, thermal interface material and heatsink design must limit Tmb to ≤95 °C under worst-case ambient conditions.
Is the CGD1042HI,112 RoHS compliant?
Yes, the CGD1042HI,112 complies with Directive 2002/95/EC (RoHS), as confirmed in its official product data sheet. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE) above threshold limits, and is suitable for environmentally regulated CATV equipment manufacturing.
Can the CGD1042HI,112 be used in two-way CATV upstream paths?
Yes, the CGD1042HI,112 supports 40–1003 MHz operation, covering the 5–42 MHz upstream band. Its 4.6 dB noise figure at 50 MHz and >20 dB input return loss below 160 MHz make it suitable for upstream boosting, provided system-level gain distribution avoids oscillation and output level remains within DOCSIS-compliant limits for upstream channel power.
