Product details
Overview
CGY1041,112 from NXP Semiconductors is a hybrid GaAs push-pull RF amplifier module optimized for CATV distribution systems, delivering 21.75 dB typical power gain at 1003 MHz, −62 dBc composite triple beat (CTB) distortion at 44 dBmV output, and 3.6 dB typical noise figure across 50–870 MHz, operating from a 24 V DC supply in a rugged SOT115J aluminum-flange package.
For engineers reviewing the CGY1041,112 datasheet, CGY1041,112 pinout, CGY1041,112 application, or CGY1041,112 equivalent, this page provides verified specifications, pin-level circuit roles, CATV-specific performance validation (79 NTSC + 75 digital channels), thermal and ESD robustness data, and direct alternative options for broadband cable infrastructure design.
Technical Context
The CGY1041,112 employs two GaAs HFET dies in a push-pull configuration to suppress even-order distortion while maintaining high linearity over 40–1003 MHz. Its unconditionally stable design eliminates external stabilization networks, and integrated ring-wave surge protection enables direct deployment in outdoor node and trunk amplifier stages without additional transient suppression.
Thermally optimized via an aluminum flange with two vertical 6-32 UNC mounting holes, the module sustains Tmb = 100 °C baseplate temperature. Input/output return loss exceeds 16 dB across full bandwidth, ensuring impedance match into 75 Ω CATV plant architecture without tuning.
Key Specifications

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 pinout; 22.5 dB max gain at 1003 MHz but higher 290 mA current draw | Optimized for lower-distortion 98 PAL channel operation (−68 dBc CTB), not NTSC/digital mix | Select when PAL-based regional deployments require tighter CTB specs and thermal budget allows higher Itot |
| CGY1040,112 | Same footprint and bias; 19.5 dB typ. gain at 1003 MHz and −58 dBc CTB - lower linearity tier | Targeted for cost-sensitive tap amplifiers or short-span distribution where full 79+75 channel loading is not required | Choose for non-critical spans where 4 dB lower gain and 4 dB worse CTB are acceptable for BOM reduction |
Compared with CGY1041,112, CGY1042,112 trades higher current for superior PAL-channel CTB, while CGY1040,112 reduces gain and linearity to cut cost-making CGY1041,112 the balanced choice for global NTSC/digital hybrid CATV deployments requiring 21 dB gain and −62 dBc CTB at 24 V.

FAQ
What is the maximum operating temperature for the CGY1041,112 mounting base?
The CGY1041,112 supports a mounting base temperature (Tmb) up to +100 °C per its limiting values table. This rating is validated under continuous 24 V DC operation with proper heatsinking and enables deployment in sealed outdoor enclosures without active cooling. Derating is not required until Tmb exceeds 100 °C, and the device remains unconditionally stable across this full range.
Does the CGY1041,112 require external DC blocking capacitors on input or output?
No, the CGY1041,112 does not require external DC blocking capacitors on input (Pin 1) or output (Pin 9). Its internal biasing network is designed for direct AC-coupled connection to 75 Ω CATV signal paths. The datasheet specifies ZS = ZL = 75 Ω operation with no mention of DC path constraints, confirming true AC-coupled RF port functionality.
What is the flatness specification for the CGY1041,112 across its full bandwidth?
The CGY1041,112 exhibits ≤0.9 dB flatness (FL) across 45–1003 MHz, defined as maximum deviation from a straight-line fit. This tight ripple ensures uniform channel loading in 79 NTSC + 75 digital channel systems, preventing tilt-induced differential gain errors in analog video and constellation rotation in digital QAM carriers.
How does the integrated ring-wave surge protection in the CGY1041,112 compare to external TVS diodes?
The CGY1041,112 integrates ring-wave surge protection compliant with IEC 61000-4-5 Level 3, eliminating the need for discrete TVS devices typically rated at 10/700 µs waveform. Unlike external TVS solutions that add capacitance and insertion loss, the monolithic protection maintains RF performance integrity while reducing PCB area and assembly cost in trunk amplifier designs.
Is the CGY1041,112 pin-compatible with other members of the CGY10xx family?
Yes, the CGY1041,112 shares identical SOT115J pinout, footprint, and mounting hole pattern with CGY1040,112 and CGY1042,112. All three variants use Pins 1 (input), 2–3 and 7–8 (grounds), 5 (+VB), and 9 (output) with identical mechanical dimensions-enabling drop-in substitution in existing layouts when adjusting gain or linearity targets.
