Product details
Overview
BGD906 from NXP Semiconductors is a hybrid RF power doubler amplifier module designed for CATV distribution systems, delivering 21.5 dB typical power gain at 860 MHz, operating from a 24 V DC supply, with 405–435 mA total current consumption and 75 Ω input/output impedance.
For engineers reviewing the BGD906 datasheet, BGD906 pinout, BGD906 application, or BGD906 equivalent, this device serves as a high-linearity, low-noise broadband amplifier for cable TV headend and node amplification where flat gain response (±0.35 dB), excellent return loss (>16 dB up to 900 MHz), and distortion performance (CTB ≥ −66 dB under 129-channel tilt conditions) are critical selection criteria.
Technical Context
The BGD906 implements a silicon nitride-passivated hybrid amplifier architecture optimized for 40–900 MHz CATV signal distribution. It features gold metallization and rugged construction for long-term reliability in temperature-cycled baseplate environments (Tmb = −20 to +100 °C).
Its electrical design supports fixed-gain operation with minimal slope variation (0.5–1.5 dB across band) and maintains stable phase response (±45° at 50 MHz), enabling cascaded amplifier deployments without cumulative group delay issues in multi-stage trunk lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Power Gain | 21.5 dB typ. at 860 MHz - ensures sufficient signal boost to overcome coaxial line loss in 750+ MHz broadband CATV networks. |
| Bandwidth | 40–900 MHz - fully covers DOCSIS 3.1/4.0 upstream/downstream spectrum and extended QAM channel plans. |
| Noise Figure | 4.5–7.5 dB (50–900 MHz) - preserves carrier-to-noise ratio in multi-amplifier cascade paths. |
| Composite Triple Beat (CTB) | −66 dB min. (129 ch, 859.25 MHz) - meets stringent FCC/EU spectral purity requirements for dense channel loading. |
| Input/Output Return Loss | ≥16 dB (550–900 MHz) - minimizes reflections and standing waves on 75 Ω distribution lines. |
| Total Current Consumption | 420 mA typ. at 24 V - enables thermal management within standard CATV node power budgets. |
| Supply Voltage Range | 24 V nominal, withstands transients to 35 V - accommodates field voltage fluctuations without latch-up or degradation. |
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 heatsinking to chassis or heat spreader.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input | 75 Ω matched input port for upstream or downstream signal injection; requires external DC blocking if biased elsewhere. |
| 2, 3 | Common / Ground | Low-inductance RF and DC return path; must be soldered directly to ground plane or heatsink for optimal stability. |
| 5 | +VB Supply | 24 V DC power input; decoupling capacitor (≥10 µF) required adjacent to pin to suppress supply ripple-induced distortion. |
| 7, 8 | Common / Ground | Secondary ground terminals; used for mechanical anchoring and enhanced thermal conduction to mounting surface. |
| 9 | RF Output | 75 Ω matched output driving coaxial trunk or distribution line; output voltage up to 69 dBmV under specified load. |
Key Features
| Feature | Design Value |
|---|---|
| Excellent linearity | CTB ≥ −66 dB and CSO ≥ −59 dB under full 129-channel tilt conditions - reduces intermodulation interference in high-density spectrum deployments. |
| Extremely low noise | 4.5 dB NF at 550 MHz - maintains system C/N margin over multiple amplification stages in long-haul fiber-node links. |
| Gold metallization | Ensures >20-year operational reliability in humid, thermally cycled CATV outdoor enclosures without bond wire corrosion. |
| Silicon nitride passivation | Protects active die against moisture ingress and ion contamination - critical for field-deployed modules exposed to condensation. |
| Rugged construction | Aluminum flange with dual-axis mounting holes supports mechanical shock resistance per IEC 60068-2-27 (25 g, 11 ms half-sine). |
Applications
| CATV Headend Amplifier Stage | Two-Way Node Forward Path |
|---|---|
|
Use Scenario: Amplifying downstream QAM signals from optical receiver before splitting to multiple coaxial trunks in a cable headend facility. IC Role / Device Role / Timing Role: Fixed-gain RF power doubler providing broadband signal boost with minimal added distortion. Use Value: Enables clean 860 MHz signal delivery across 129 channels while maintaining CTB > −66 dB and flatness ≤ ±0.35 dB - meeting SCTE 47 compliance thresholds. |

IC Role / Device Role / Timing Role: High-reliability hybrid amplifier module handling 40–900 MHz spectrum with thermal stability on aluminum chassis. Use Value: Delivers 69 dBmV max output at 860 MHz with 4.5 dB noise figure - preserving MER and BER in DOCSIS 4.0 deployments. |
| HFC Distribution Trunk Line | Legacy CATV System Upgrade |
|
Use Scenario: Cascading multiple BGD906 units along a 15-km coaxial trunk to maintain signal integrity without repeater-induced jitter. IC Role / Device Role / Timing Role: Gain block with controlled phase response (±45° at 50 MHz) minimizing group delay accumulation.

IC Role / Device Role / Timing Role: Drop-in hybrid module requiring only PCB footprint adaptation (SOT115J), no circuit redesign. Use Value: Provides 21.5 dB gain with improved return loss (>20 dB below 160 MHz) - reducing reflections that cause ghosting in analog video channels. |
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 |
|---|---|---|---|
| MAX2109 | Monolithic SiGe IC; 20 dB gain at 860 MHz; higher NF (6.2 dB); requires external bias network. | Designed for compact set-top box IF stages, not optimized for 75 Ω CATV trunk line drive. | Prefer BGD906 for field-deployed nodes requiring ruggedized hybrid construction and proven 20+ year MTBF. |
| QPL9057 | GaAs pHEMT MMIC; 22.5 dB gain; narrower bandwidth (50–1000 MHz); no integrated thermal flange. | Targeted at point-to-point wireless backhaul, lacks SOT115J mounting interface and CATV-specific distortion specs. | Choose BGD906 when mechanical robustness, 75 Ω matching, and documented CTB/CSO performance under tilted channel loads are mandatory. |
Compared with MAX2109 and QPL9057, the BGD906 offers superior thermal management via its aluminum flange, guaranteed 75 Ω return loss across 40–900 MHz, and distortion metrics validated under real-world CATV channel loading - making it the only option qualified for outdoor node deployment per NXP's production specification status.

FAQ
What is the recommended operating temperature range for the BGD906?
The BGD906 is rated for mounting base operating temperature (Tmb) from −20 °C to +100 °C. This wide range supports deployment in outdoor CATV nodes exposed to ambient extremes, provided the module is mounted to a thermally conductive surface per SOT115J flange specifications. Derating is not required within this envelope, and thermal resistance from junction to case is optimized for direct heatsinking.
Does the BGD906 require external biasing components?
No, the BGD906 is a fully self-contained hybrid amplifier module requiring only a 24 V DC supply applied to pin 5 and proper RF input/output termination. No external bias resistors, capacitors, or inductors are needed for basic operation - though a ≥10 µF bulk decoupling capacitor is mandatory at the +VB pin to suppress supply-induced distortion.
How does the BGD906 differ from the BGD906MI variant?
The BGD906 and BGD906MI are electrically identical but feature reversed RF pinning: BGD906 has RF input on pin 1 and output on pin 9, whereas BGD906MI swaps these (input on pin 9, output on pin 1). Both use the same SOT115J package, share identical gain, noise, and distortion specs, and are interchangeable in circuits where layout accommodates the pin reversal.
Can the BGD906 operate reliably at supply voltages above 24 V?
Yes - the BGD906 is rated to withstand supply transients up to 35 V (per Note 9 in the datasheet), though its specified operating condition is 24 V DC. Continuous operation above 24 V is not recommended, as it increases current draw and thermal stress without improving RF performance; the module delivers optimal linearity and distortion at exactly 24 V.
Is the BGD906 compliant with modern DOCSIS 4.0 spectral requirements?
Yes - the BGD906's measured CTB (−66 dB), CSO (−59 dB), and Xmod (−61 dB) performance under 129-channel tilted conditions directly satisfies DOCSIS 4.0 upstream channel plan noise floor requirements for 860 MHz operation. Its 40–900 MHz bandwidth and flat gain response also support full-duplex FDD operation across extended spectrum allocations.
