Product details
Overview
CGY1043,112 from NXP Semiconductors is a hybrid GaAs push-pull amplifier module in SOT115J package, operating at 24 V DC supply, delivering 23.75 dB typical power gain at 1003 MHz with 265–280 mA total current draw and 40–1003 MHz bandwidth for CATV line amplification. It integrates ring-wave surge protection and achieves −62 dBc composite triple beat (CTB) at 44 dBmV output under 79 NTSC + 75 digital channel loading.
For engineers reviewing the CGY1043,112 datasheet, CGY1043,112 pinout, CGY1043,112 application, or CGY1043,112 equivalent, key selection criteria include its 75 Ω input/output impedance match, unconditionally stable HFET-based architecture, thermal robustness up to 100 °C mounting base temperature, and compliance with RoHS Directive 2002/95/EC.
Technical Context
This amplifier employs dual GaAs HFET dies in a push-pull configuration to suppress even-order distortion and enable flat frequency response across 40–1003 MHz. Its unconditionally stable design eliminates external stabilization networks, while integrated ESD protection (2000 V HBM) and ring-wave surge immunity support deployment in harsh cable infrastructure environments.
The SOT115J package features an aluminum flange with 2 vertical and 2 horizontal 6-32 UNC mounting holes, enabling direct thermal coupling to heatsinks. Input and output return loss exceeds 16 dB across full bandwidth, ensuring minimal signal reflection in 75 Ω CATV distribution systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Power gain | 23.75 dB typ. at 1003 MHz - enables single-stage amplification of full 40–1003 MHz CATV spectrum without cascading stages |
| Bandwidth | 40 MHz to 1003 MHz - supports simultaneous NTSC, PAL, and digital channel transmission (55.25–1003 MHz) |
| Composite triple beat (CTB) | −62 dBc at 44 dBmV output - meets stringent distortion requirements for dense multi-channel analog/digital CATV systems |
| Total current | 265–280 mA at 24 V - defines thermal load and power supply sizing for headend or node amplifier designs |
| Input/output impedance | 75 Ω matched - ensures seamless integration into standard coaxial CATV plant without impedance-matching components |
| Mounting base temp. range | −20 °C to +100 °C - supports operation in outdoor cabinets and temperature-uncontrolled amplifier housings |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CGY1042,112 | Same SOT115J package and GaAs push-pull architecture but rated for 40–870 MHz bandwidth; 23.3 dB typ. gain at 870 MHz | Limited to sub-870 MHz systems; unsuitable for 1003 MHz digital channel extension | Select CGY1042,112 only when system bandwidth is capped below 870 MHz and cost optimization is prioritized |
| CGY1045,112 | Extended 40–1218 MHz bandwidth; 23.5 dB typ. gain at 1218 MHz; higher 290 mA max current draw | Supports DOCSIS 4.0 extended spectrum (up to 1218 MHz); requires larger heatsink due to higher power dissipation | Choose CGY1045,112 for future-proof deployments requiring >1003 MHz headroom, accepting higher thermal and supply demands |
Compared with CGY1042,112 and CGY1045,112, the CGY1043,112 uniquely balances 1003 MHz upper-frequency coverage, −62 dBc CTB performance, and 265–280 mA efficiency-making it optimal for current-generation digital CATV systems operating up to 1003 MHz without over-engineering.

FAQ
What is the maximum supply voltage rating for CGY1043,112?
The absolute maximum supply voltage for CGY1043,112 is 30 V DC, as specified in Table 4 (Limiting values) of the NXP datasheet. Operation above 24 V DC reduces reliability and may trigger thermal shutdown; sustained use at 30 V is not recommended. The CGY1043,112 is characterized and guaranteed for stable performance at its nominal 24 V DC supply condition.
Does CGY1043,112 require external biasing components?
No, CGY1043,112 is a fully self-biased hybrid module with internal DC bias networks for its GaAs HFET dies. Only external 24 V DC supply decoupling (10 µF + 100 nF) and 75 Ω RF terminations are required. The CGY1043,112 eliminates need for external gate/base resistors, emitter degeneration, or temperature-compensation circuits.
Can CGY1043,112 be used in 50 Ω systems?
CGY1043,112 is strictly designed and characterized for 75 Ω CATV systems. Its input and output return loss, gain flatness, and distortion performance are validated only at ZS = ZL = 75 Ω. Using CGY1043,112 in 50 Ω systems degrades RLin/RLout, increases CTB/CSO, and voids specification compliance-no 50 Ω application data exists for this part.
What is the thermal resistance from junction to case for CGY1043,112?
The datasheet does not specify junction-to-case thermal resistance (RθJC) for CGY1043,112. Instead, NXP provides mounting base temperature limits (Tmb = −20 °C to +100 °C) and flange-mounting instructions. Thermal design must ensure the aluminum flange remains within this range; RθJC is not a rated parameter for this hybrid module.
Is CGY1043,112 qualified for automotive applications?
No, CGY1043,112 is explicitly designated as a non-automotive qualified product. Per Section 9.3 of the NXP datasheet, it is neither tested nor warranted for automotive use, including AEC-Q100 qualification. The CGY1043,112 is intended solely for CATV infrastructure and must not be deployed in safety-critical or automotive environments.
