Product details
Overview
BGD802/02,112 from NXP Semiconductors is a hybrid RF power doubler amplifier module designed for CATV distribution amplifiers and trunk-line repeaters. It delivers 18.5 dB small-signal gain at 860 MHz, operates from a 24 V DC supply, consumes ≤410 mA total current, and maintains ±0.5 dB flatness across 40–860 MHz in 75 Ω systems.
For engineers reviewing the BGD802/02,112 datasheet, BGD802/02,112 pinout, BGD802/02,112 application, or BGD802/02,112 equivalent, this page provides verified pin functions, CATV-specific distortion metrics (CTB ≥ −66 dB, CSO ≥ −67.5 dB), thermal limits (Tmb = −20 to +100 °C), SOT115J package dimensions, and two validated alternatives for broadband cable infrastructure designs.
Technical Context
The BGD802/02,112 implements a monolithic hybrid architecture with silicon nitride passivation and gold metallization for reliability in high-voltage CATV environments. Its input and output return losses exceed 14 dB across 40–860 MHz, enabling stable 75 Ω system integration without external matching networks.
It supports dual-tone and multi-carrier operation per DIN45004B test methods, delivering measured CTB of −66 dB (49-channel), −56.5 dB (129-channel), and −60.5 dB (110-channel) configurations - all at 44–47 dBmV output levels. The module withstands 30 V supply transients while operating nominally at 24 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Power Gain | 18.5 dB at 860 MHz - ensures sufficient headroom for cascaded amplification in trunk-line applications |
| Frequency Range | 40–860 MHz - fully covers North American and European CATV spectrum including DOCSIS 3.1 upstream/downstream bands |
| Output Voltage | 63.5 dBmV typical - meets carrier-level requirements for 75 Ω coaxial distribution without additional buffering |
| Composite Triple Beat (CTB) | −66 dB (49 channels, 47 dBmV) - satisfies stringent linearity specs for analog/digital hybrid channel loading |

Pinout & Package
SOT115J package: rectangular single-ended metal flange with 7 gold-plated in-line leads, 2 vertical 6-32 UNC mounting holes, and aluminum base for direct thermal coupling to heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input | 75 Ω matched input port; connects directly to preceding stage without external DC blocking or matching |
| 2, 3 | Common Ground | DC and RF ground reference points; must be low-inductance connection to system ground plane |
| 5 | +VB Supply | 24 V DC input (max 30 V transient tolerant); requires local 10 µF/100 nF decoupling at pin |
| 7, 8 | Common Ground | Secondary ground terminals; used for mechanical stability and RF return path redundancy |
| 9 | RF Output | 75 Ω matched output port; drives downstream coaxial line or next amplifier stage directly |
Key Features
| Feature | Design Value |
|---|---|

| Excellent return loss | Input/output return losses >14 dB across full 40–860 MHz band reduce need for external isolators or circulators |
| Low noise figure | 4.5 dB NF at 50 MHz enables use as first-stage amplifier in low-noise headend receiver chains |
Applications
| CATV Trunk Amplifier | Headend Distribution Module |
|---|---|
|
Use Scenario: Amplifying signals over 1–3 km coaxial trunk lines between hub and node, handling 49–129 analog/digital channels. IC Role / Device Role / Timing Role: RF power doubler amplifier providing gain and linearity in the forward path of active trunk segments. Use Value: Delivers −66 dB CTB at 47 dBmV output, meeting SCTE 47-2019 linearity requirements for legacy and hybrid fiber-coax networks. |
Use Scenario: Signal distribution from headend modulators to multiple optical transmitters or RF combiners. IC Role / Device Role / Timing Role: Broadband gain block ensuring flat response and minimal intermodulation before optical conversion. Use Value: ±0.2 dB typical flatness (40–860 MHz) eliminates need for slope compensation networks in multi-output distribution racks. |
| Node Power Doubler | Two-Way Splitter Amplifier |
|
Use Scenario: Boosting downstream signal level at fiber-deep nodes prior to 16-way passive splitting. IC Role / Device Role / Timing Role: Final-stage RF amplifier compensating for split loss while maintaining distortion performance. Use Value: 63.5 dBmV output voltage enables ≥10 dB margin above minimum required level after 16-way split (−12 dB loss). |
Use Scenario: Bi-directional amplification in two-way HFC architectures where same physical path carries upstream/downstream traffic. IC Role / Device Role / Timing Role: Forward-path doubler amplifier operating in dedicated downstream band (54–860 MHz). Use Value: Input/output return losses >14 dB minimize echo and reflection-induced upstream interference in shared coax paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power doubler amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2472ETE+ | SiGe MMIC; 5 V supply; 17 dB gain at 860 MHz; 2.5 dB NF; SOT23-6 package | Lower power, lower voltage; suited for indoor set-top box IF stages, not outdoor trunk amplification | Select when board space is constrained and thermal budget is limited to <1 W; not rated for 24 V or CATV linearity specs |
| QPL9057 | GaAs pHEMT; 5 V supply; 20 dB gain at 860 MHz; −62 dB CTB (49 ch); 3 mm × 3 mm QFN | Higher gain but lower distortion floor; optimized for DOCSIS 4.0 upstream boosters, not downstream trunk | Choose for compact, high-efficiency upstream amplification where CTB > −62 dB is acceptable; lacks SOT115J thermal mass for continuous 24 V operation |
Compared with BGD802/02,112, MAX2472ETE+ offers smaller footprint and lower supply voltage but cannot meet CATV trunk-line linearity or thermal requirements, while QPL9057 provides higher gain in a miniature package yet trades off CTB performance and thermal robustness needed for outdoor 24 V deployments.

FAQ
What is the maximum supply voltage rating for the BGD802/02,112?
The BGD802/02,112 has an absolute maximum supply voltage (VB) of 25 V per limiting values, but the datasheet confirms it can withstand transient surges up to 30 V. For reliable continuous operation, NXP specifies 24 V DC as the nominal supply - using voltages above 25 V risks permanent damage, and operation at 30 V is only permissible for short-duration transients.
Does the BGD802/02,112 require external biasing or matching components?
No, the BGD802/02,112 is a fully self-contained hybrid module with internal biasing and 75 Ω input/output impedance matching. It requires only a 24 V DC supply with local decoupling (10 µF + 100 nF), proper grounding via pins 2, 3, 7, and 8, and direct 75 Ω RF connections to input (pin 1) and output (pin 9). No external baluns, transformers, or tuning stubs are needed.
What is the thermal mounting requirement for the BGD802/02,112?
The BGD802/02,112 uses a thermally conductive aluminum flange in the SOT115J package and must be mounted directly to a heatsink using the two vertical 6-32 UNC mounting holes. The datasheet specifies an operating mounting base temperature (Tmb) range of −20 to +100 °C - effective thermal interface (e.g., thermal grease or pad) and heatsink sizing must ensure the flange stays within this limit at 410 mA load.
How does the BGD802/02,112 perform in multi-carrier distortion tests?
The BGD802/02,112 achieves −66 dB composite triple beat (CTB) with 49 flat channels at 47 dBmV output, −56.5 dB CTB with 129 channels at 44 dBmV, and −60.5 dB CTB with 110 channels at 44 dBmV - all measured per DIN45004B. These results confirm its suitability for dense channel loading in modern digital CATV systems without requiring post-compensation circuitry.
Is the BGD802/02,112 qualified for outdoor or harsh-environment deployment?
Yes, the BGD802/02,112 is explicitly designed for outdoor CATV infrastructure. Its silicon nitride passivation, gold metallization, rugged aluminum flange, and specified operating mounting base temperature range (−20 to +100 °C) meet industry requirements for pole-mounted amplifiers, pedestal nodes, and aerial distribution cabinets exposed to humidity, thermal cycling, and vibration.
