Product details
Overview
CGY1047,112 from NXP Semiconductors is a GaAs-based hybrid push-pull RF amplifier module in SOT115J package, designed for CATV line amplification with 27 dB typical gain at 1003 MHz, 40–1003 MHz bandwidth, 24 V DC supply, and 75 Ω input/output impedance. It delivers −64 dBc CTB and 65 dBc CCN at 44 dBmV output under full-channel load.
For engineers reviewing the CGY1047,112 datasheet, CGY1047,112 pinout, CGY1047,112 application, or CGY1047,112 equivalent, key selection criteria include flatness (≤0.8 dB), input/output return loss (>16 dB up to 1003 MHz), thermal robustness (Tmb ≤ +100 °C), ESD rating (2000 V HBM), and integrated ring wave surge protection for outdoor node reliability.
Technical Context
This hybrid amplifier employs two GaAs HFET dies in a push-pull configuration to suppress even-order distortion while maintaining high linearity and unconditional stability across 40–1003 MHz. Its thermally optimized aluminum flange package enables direct heatsink mounting and stable operation at mounting base temperatures up to +100 °C.
The module integrates common-mode RF grounding via pins 2, 3, 7, and 8, supports 24 V DC bias on pin 5, and features gold-plated in-line leads for low-contact resistance and corrosion resistance in humid CATV environments. Input (pin 1) and output (pin 9) are matched to 75 Ω without external tuning components.

Pinout & Package
SOT115J is a rectangular single-ended hybrid module with aluminum flange, 2 vertical and 2 horizontal 6-32 UNC mounting holes, and 7 gold-plated in-line leads. Thermal path is optimized via flange-to-heatsink interface; RF I/O are internally matched to 75 Ω.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input | 75 Ω matched input port; connects directly to upstream coaxial feed without external matching network. |
| 2, 3 | Common Ground | DC and RF ground reference points; must be connected to low-inductance chassis ground for stability. |
| 5 | +VB Supply | 24 V DC bias input; requires local 10 µF/100 nF decoupling near pin for ripple suppression. |
| 7, 8 | Common Ground | Additional ground terminals for mechanical rigidity and RF return path redundancy. |
| 9 | RF Output | 75 Ω matched output port; drives downstream coaxial trunk or drop cable with minimal VSWR. |
Key Features

Applications
| CATV Trunk Amplifier | HFC Node Amplifier |
|---|---|
Use Scenario: Amplifying downstream RF signals over 1–3 km coaxial trunk segments between hub and optical node. IC Role / Device Role / Timing Role: Primary RF gain stage delivering flat broadband amplification with minimal distortion accumulation. Use Value: 27.75 dB gain and ≤0.8 dB flatness ensure consistent channel loading across 40–1003 MHz, reducing need for per-channel tilt correction. |
Use Scenario: Final-stage amplification inside fiber-deep optical nodes before signal distribution to homes. IC Role / Device Role / Timing Role: Line driver providing high-output, low-noise amplification for multi-carrier DOCSIS 3.1/4.0 signals. Use Value: −64 dBc CTB and 65 dBc CCN meet DOCSIS spectral purity requirements at 44 dBmV output under full-channel load. |

IC Role / Device Role / Timing Role: Gain block compensating for passive splitter loss while preserving CNR and distortion margins. Use Value: 4.0 dB noise figure up to 870 MHz maintains upstream SNR integrity in shared return-path architectures. |
Use Scenario: Bidirectional amplification in active splitters supporting both downstream broadcast and upstream TDMA/OFDMA return paths. IC Role / Device Role / Timing Role: Full-duplex RF amplifier with symmetric 75 Ω I/O and high isolation between bands. Use Value: ≥16 dB input/output return loss across 45–1003 MHz minimizes echo and intermodulation in split-band configurations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar RF amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CGY1048,112 | Same SOT115J package and GaAs push-pull architecture but rated for 28 dB gain (typ.) and higher current draw (280 mA). | Targeted for longer trunk runs requiring +1 dB gain margin; less suitable for space-constrained nodes due to higher thermal load. | Select CGY1048,112 only when system link budget demands >27.75 dB gain and thermal design accommodates +30 mA extra current. |
| MAX2130ETJ+ | SiGe MMIC amplifier in 32-pin TQFN; 26 dB gain, 2.2 GHz bandwidth, but no integrated surge protection or flange cooling. | Designed for indoor equipment; lacks ruggedized packaging and CATV-specific linearity optimization. | Use MAX2130ETJ+ only in controlled-environment headend or lab settings-not for outdoor node deployment. |
Compared with CGY1047,112, CGY1048,112 offers higher gain at increased power and thermal cost, while MAX2130ETJ+ trades CATV-optimized linearity and ruggedness for wider bandwidth and surface-mount flexibility-neither is pin-compatible, and both require PCB redesign and thermal reassessment.

FAQ
What is the maximum supply voltage for CGY1047,112?
The absolute maximum supply voltage for CGY1047,112 is 30 V DC, as specified in the limiting values table. Operation above this threshold risks permanent damage. The device is characterized and optimized for 24 V DC nominal supply, where it delivers 27.75 dB typical gain and −64 dBc CTB performance. Exceeding 30 V violates IEC 60134 absolute maximum ratings and voids reliability guarantees.
Does CGY1047,112 require external matching components?
No, CGY1047,112 does not require external matching components. Its input (pin 1) and output (pin 9) are internally matched to 75 Ω across 40–1003 MHz, enabling direct connection to standard CATV coaxial infrastructure. The datasheet confirms ZS = ZL = 75 Ω in all gain, distortion, and return loss measurements-no external LC networks or stubs are needed for basic operation.
What is the thermal mounting requirement for CGY1047,112?
CGY1047,112 must be mounted with its aluminum flange to a heatsink using the two vertical 6-32 UNC mounting holes. Maximum mounting base temperature (Tmb) is +100 °C; operation beyond this degrades gain flatness and accelerates aging. Thermal interface material with ≤0.5 °C·in²/W resistance is recommended to maintain junction temperature within safe limits under 250 mA total current draw.
Is CGY1047,112 compliant with RoHS and ESD standards?
Yes, CGY1047,112 is compliant with Directive 2002/95/EC (RoHS) and certified for 2000 V electrostatic discharge per Human Body Model (HBM) per JEDEC JESD22-A114E. It also meets IEC61000-4-2 level 4 (2000 V contact discharge) for system-level ESD immunity. These specifications are verified in the "Features and benefits" and "Limiting values" sections of the official NXP datasheet Rev. 2.
Can CGY1047,112 be used in bidirectional (two-way) CATV systems?
Yes, CGY1047,112 is suitable for bidirectional CATV systems as a downstream amplifier stage. Its ≥16 dB input and output return loss across 45–1003 MHz minimizes echo and intermodulation in split-band architectures. However, it is not designed for upstream amplification-its noise figure (4.0 dB) and gain profile are optimized for downstream, so separate low-noise upstream amplifiers remain necessary in full two-way nodes.
