Product details
Overview
BGY787,112 from NXP Semiconductors is a hybrid push-pull RF amplifier module designed for CATV distribution systems, delivering 21.5 dB typical power gain at 750 MHz, operating from a 24 V DC supply with 220–240 mA total current draw and optimized for 75 Ω impedance matching across 40–750 MHz.
For engineers reviewing the BGY787,112 datasheet, BGY787,112 pinout, BGY787,112 application, or BGY787,112 equivalent, this page provides verified gain flatness (±0.2 dB), noise figure (4–6.5 dB), composite distortion performance (CTB ≥ −54.5 dB), and SOT115J mechanical interface details critical for broadband cable infrastructure design.
Technical Context
The BGY787,112 implements a silicon nitride-passivated hybrid push-pull architecture to achieve high linearity and low distortion in wideband CATV amplification. Its input and output return losses exceed 14 dB across 40–750 MHz, supporting stable 75 Ω system matching without external tuning networks.
It operates with fixed 24 V DC bias and integrates ruggedized gold-metallized leads and aluminum flange mounting for thermal reliability in headend and node applications. The module withstands transient supply voltages up to 30 V while maintaining specified RF performance under continuous 24 V operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MACOM MABT-011000 | Higher gain (24 dB), narrower bandwidth (50–1000 MHz), no integrated flange mounting | Used in lab test equipment and compact active splitters; lacks SOT115J mechanical robustness for field deployment | Select when higher gain and wider upper-frequency coverage outweigh mechanical integration needs |
| Qorvo QPB0060 | Monolithic GaAs pHEMT design, lower current (180 mA), smaller 6-pin SOT-115D package | Targeted at space-constrained indoor nodes; not rated for 30 V transients or aluminum-flange thermal coupling | Choose for lower power consumption and PCB footprint reduction where thermal derating is managed externally |
Compared with MABT-011000 and QPB0060, the BGY787,112 offers superior mechanical ruggedness via its SOT115J flange, guaranteed 24 V/220–240 mA operation with 30 V surge tolerance, and proven 110-channel CATV linearity-making it the preferred choice for outdoor headend and node deployments demanding long-term reliability.

FAQ
What is the recommended operating voltage for the BGY787,112?
The BGY787,112 is designed for nominal 24 V DC operation, with total current consumption of 220–240 mA under typical conditions. It can withstand supply transients up to 30 V per its absolute maximum ratings, but sustained operation above 24 V is not recommended as it may accelerate aging and degrade long-term linearity performance of the BGY787,112.
Does the BGY787,112 require external biasing or matching components?
No, the BGY787,112 integrates internal biasing and is fully 75 Ω input/output matched across 40–750 MHz. External DC blocking capacitors are required only if the RF source or load introduces DC potential; no external inductors, transformers, or tuning stubs are needed for standard CATV applications using the BGY787,112.
What is the thermal management requirement for the BGY787,112?
The BGY787,112 uses an aluminum flange (SOT115J) designed for direct mounting to a heatsink or chassis. Its mounting base temperature must remain between −20 °C and +100 °C. For continuous operation at full 240 mA, a thermal resistance of ≤1.5 °C/W from flange to ambient is recommended to maintain case temperature ≤30 °C, ensuring stable gain and distortion performance of the BGY787,112.
How does the BGY787,112 perform in multi-channel CATV systems?
The BGY787,112 delivers −54.5 dB typical composite triple beat (CTB) and −57.5 dB composite second order (CSO) distortion with 110 channels flat at 44 dBmV output, meeting industry standards for large-scale cable networks. Its slope cable equivalent of ≤1 dB and flatness of ±0.2 dB ensure consistent channel loading without per-channel gain adjustment in systems using the BGY787,112.
Is the BGY787,112 suitable for DOCSIS 4.0 or full-duplex upstream applications?
The BGY787,112 is characterized for 40–750 MHz downstream operation and is not specified for DOCSIS 4.0's extended 1.2 GHz downstream band or full-duplex upstream frequencies above 204 MHz. While its 75 Ω interface and low noise figure support upstream use in legacy 5–42 MHz bands, its gain and distortion data beyond 770 MHz are not validated - making it unsuitable for DOCSIS 4.0 deployment unless paired with additional filtering and gain stages outside the BGY787,112's rated bandwidth.
