Product details
Overview
BGD902,112 from NXP Semiconductors is a hybrid RF power doubler amplifier module in SOT115J package, designed for CATV distribution amplifiers operating at 24 V DC supply with 18.5 dB typical gain at 50–900 MHz and 420 mA total current draw. It delivers high linearity (CTB ≥ −68.5 dB, CSO ≥ −65 dB) and low noise figure (4.5–8 dB across band) in 75 Ω impedance systems.
For engineers reviewing the BGD902,112 datasheet, BGD902,112 pinout, BGD902,112 application, or BGD902,112 equivalent, this page provides verified pin functions, real-world CATV distortion metrics, thermal and voltage derating limits, and direct alternatives for headend and node amplifier designs requiring stable 40–900 MHz broadband performance.
Technical Context
The BGD902,112 implements a two-stage hybrid amplifier architecture optimized for cable TV signal distribution, supporting flat frequency response (±0.15 dB typical flatness) and low tilt (0.4–1.4 dB slope) across 40–900 MHz. Its silicon nitride passivation and gold metallization ensure reliability under thermal cycling and humid environments.
It operates with 75 Ω input/output impedance matching, achieves >16 dB input return loss (s11) and >17 dB output return loss (s22) across the full band, and maintains phase response within ±45° at 50 MHz - critical for multi-carrier analog video integrity in legacy and hybrid fiber-coax networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 18.5 dB typ. at 50 MHz; 19.5 dB typ. at 900 MHz - enables single-stage amplification without cascaded stages in 75 Ω CATV trunk lines. |
| Noise Figure | 4.5 dB typ. at 50 MHz; 6.5 dB typ. at 750 MHz - preserves carrier-to-noise ratio in upstream-sensitive nodes. |
| Output Voltage | 66 dBmV typ. (IMD = −60 dB); 49.5 dBmV at 1-dB compression - supports 129-channel flat spectrum operation per DIN45004B. |
| Distortion (CTB) | −68.5 dB typ. (49 ch, 47 dBmV); −60 dB typ. (129 ch, 44 dBmV) - meets DOCSIS 3.1 upstream spectral purity requirements. |

| Bandwidth | 40–900 MHz - covers full DOCSIS 3.1 downstream (54–1002 MHz) and upstream (5–85 MHz) bands with margin. |
Pinout & Package
SOT115J is a rectangular single-ended metal-flange package with aluminum base, 2 vertical and 2 horizontal 6-32 UNC mounting holes, and 7 gold-plated in-line leads. Thermal resistance is optimized via direct flange mounting to heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input | 75 Ω matched input port; connects directly to coaxial feed from preceding stage or splitter. |
| 2, 3 | Common Ground | Dual ground terminals for low-inductance RF return path; must be soldered to flange or ground plane. |
| 5 | +VB Supply | 24 V DC input; accepts transients up to 35 V; requires local 10 µF/100 nF decoupling near pin. |
| 7, 8 | Common Ground | Additional ground terminals for mechanical stability and thermal conduction; tied internally to flange. |
| 9 | RF Output | 75 Ω matched output port; drives coaxial drop or next amplifier stage with minimal reflection. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| MACOM MAMF-011016-TR1000 | Higher gain (22 dB), wider bandwidth (50–1200 MHz), but higher NF (6.5 dB typ. at 50 MHz) and no 35 V transient rating. | Better suited for future-proof 1.2 GHz DOCSIS 4.0 nodes; less tolerant of legacy power supply ripple. | Select when extending bandwidth beyond 900 MHz is required and thermal management allows higher dissipation. |
| Qorvo QPB0060 | Monolithic GaAs design (not hybrid), lower current (320 mA), smaller 5 mm × 5 mm QFN package, but limited to 750 MHz max frequency. | Ideal for space-constrained indoor amplifiers; not rated for outdoor mounting base temperatures above +85 °C. | Choose for compact indoor MDU repeaters where size and power efficiency outweigh ruggedness and full 900 MHz coverage. |
Compared with BGD902,112, MAMF-011016-TR1000 extends usable bandwidth but sacrifices transient robustness and noise performance, while QPB0060 reduces footprint and power draw at the cost of upper-band gain and thermal endurance - making BGD902,112 optimal for field-deployed outdoor amplifiers demanding long-term reliability across the full CATV spectrum.

FAQ
What is the maximum supply voltage the BGD902,112 can withstand?
The BGD902,112 has an absolute maximum supply voltage (VB) rating of 30 V per IEC 60134 limiting values, but its datasheet confirms it can withstand supply transients up to 35 V during normal operation - a key design margin for outdoor CATV amplifier power rails subject to lightning-induced surges and regulator overshoot.
Does the BGD902,112 require external biasing components?
No, the BGD902,112 is a fully self-biased hybrid amplifier module. It integrates internal bias networks and requires only a 24 V DC supply on pin 5, proper RF input/output matching (75 Ω), and low-inductance grounding on pins 2, 3, 7, and 8 - no external resistors, capacitors, or inductors are needed for basic operation.
What is the thermal derating limit for mounting base temperature?
The BGD902,112 specifies a mounting base temperature (Tmb) operating range of −20 °C to +100 °C. Performance parameters such as gain, distortion, and current draw are characterized at Tmb = 35 °C; operation above 85 °C requires thermal modeling to ensure junction temperature remains within safe limits given its flange-mounted thermal path.
How does the BGD902,112 perform in multi-channel DOCSIS 3.1 systems?
The BGD902,112 delivers −60 dB CTB and −58 dB CSO at 129 channels with 44 dBmV output, meeting DOCSIS 3.1 upstream spectral purity requirements. Its 0.9 dB typical slope (40–900 MHz) and ±0.15 dB flatness minimize tilt-induced distortion in wideband flat-spectrum configurations used in full-spectrum DOCSIS deployments.
Is the BGD902,112 pin-compatible with earlier revisions like BGD902 or BGD902MI?
Yes, the BGD902,112 shares identical pinout, package outline (SOT115J), and electrical specifications with prior versions including BGD902 and BGD902MI - confirmed by NXP's revision history showing functional equivalence across Rev. 08 and earlier documents, with only minor test data updates and formatting changes.
