Product details
Overview
CGY1032,112 from NXP Semiconductors is a GaAs-based hybrid push-pull RF amplifier module designed for CATV distribution systems, delivering 33.0 dB typical power gain at 1003 MHz, −62 dBc composite triple beat (CTB) distortion at 44 dBmV output, and 265–280 mA total current draw at 24 V DC supply. It operates across 40–1003 MHz with 75 Ω input/output impedance and integrated ring-wave surge protection.
For engineers reviewing the CGY1032,112 datasheet, CGY1032,112 pinout, CGY1032,112 application, or CGY1032,112 equivalent, this page provides verified specifications, SOT115J package details, CATV system integration guidance, and validated alternative options for broadband cable amplifier design and replacement.
Technical Context
The CGY1032,112 employs dual GaAs HFET dies in a push-pull configuration to achieve unconditional stability and low distortion across the full 40–1003 MHz CATV band. Its thermally optimized aluminum-flange SOT115J package enables direct heatsink mounting and maintains Tmb ≤ 100 °C under full load.
It delivers flat frequency response (≤0.85 dB flatness), high input/output return loss (≥16 dB up to 1003 MHz), and ESD robustness (2000 V HBM/IEC61000-4-2), supporting multi-channel NTSC/PAL/digital signal amplification without external biasing or matching networks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CGY1032,118 | Same die, identical electrical specs, but supplied in tape-and-reel packaging (SOT115J) instead of bulk | No functional difference; selected for automated SMT assembly vs. manual/hand-soldered deployment | Choose CGY1032,118 for pick-and-place manufacturing; CGY1032,112 for prototyping or low-volume repair |
| CGY1032,127 | Same die and SOT115J package, but with enhanced ESD rating (4000 V HBM) and extended Tmb range (−40 to +105 °C) | Targeted for outdoor plant equipment exposed to wider ambient extremes and higher ESD stress | Choose CGY1032,127 for outside-plant amplifiers; CGY1032,112 for indoor headend or node cabinet use |

FAQ
What is the maximum supply voltage for the CGY1032,112?
The CGY1032,112 has an absolute maximum supply voltage (VB) of 30 V DC, though it is characterized and intended for operation at 24 V DC. Exceeding 30 V risks permanent damage per IEC 60134 limiting values. The CGY1032,112 draws 265–280 mA at 24 V, resulting in ~6.4–6.7 W dissipation that must be managed via its aluminum flange mount.
Does the CGY1032,112 require external biasing or matching components?
No, the CGY1032,112 is internally biased and features 75 Ω input/output impedance matching across 40–1003 MHz. It requires only a 24 V DC supply on pin 5, proper grounding of pins 2, 3, 7, and 8 to the aluminum flange, and decoupling capacitors near the +VB pin. No external baluns, bias tees, or matching networks are needed for standard CATV operation.
What is the flatness specification of the CGY1032,112 over its operating bandwidth?
The CGY1032,112 exhibits ≤0.85 dB flatness (peak deviation to straight line) from 45 MHz to 1003 MHz at 24 V DC and 35 °C mounting base temperature. This tight flatness ensures uniform gain across NTSC, PAL, and digital channel bands without requiring external equalization, directly supporting 79 NTSC + 75 digital channels at −6 dB offset.
How does the CGY1032,112 handle electrostatic discharge (ESD)?
The CGY1032,112 is rated for 2000 V ESD per Human Body Model (HBM) and IEC61000-4-2 standards, achieved through integrated protection circuitry. This level meets Class 2 ESD classification and provides sufficient robustness for handling, PCB assembly, and field installation in controlled CATV environments-though additional board-level protection may be added for uncontrolled outdoor exposure.
Can the CGY1032,112 be used in two-way (upstream/downstream) CATV systems?
Yes, the CGY1032,112 is commonly deployed in the downstream path of two-way HFC systems due to its high linearity (−62 dBc CTB), low noise figure (3.4 dB typ. at 50 MHz), and unconditional stability. While not designed for upstream amplification (which typically requires lower noise and different gain profiles), its 40–1003 MHz bandwidth and 75 Ω interface make it ideal for downstream signal boosting in active splitters and node amplifiers where the CGY1032,112 operates as the primary gain stage.
