Product details
Overview
BGR269 from NXP Semiconductors is a high-performance reverse amplifier designed for CATV distribution systems, delivering 35 dB power gain across 5–200 MHz with 75 Ω input/output impedance, 24 V DC supply operation, and rugged SOT115J metal-flange packaging. It serves as the reverse-path amplifier in two-way cable networks handling upstream return signals.
For engineers reviewing the BGR269 datasheet, BGR269 pinout, BGR269 application, or BGR269 equivalent, this page provides verified specifications including gain flatness (±0.6 dB), input/output return loss (>20 dB), composite triple beat (−74 dB at 37 MHz), noise figure (5.3 dB @ 70 MHz), and transient-rated supply (up to 35 V).
Technical Context
The BGR269 operates as a broadband RF amplifier optimized for reverse-path signal amplification in hybrid fiber-coax (HFC) networks. Its design targets 75 Ω impedance matching, minimal group delay variation, and high linearity to preserve multi-channel upstream signal integrity under real-world CATV loading conditions.
It employs silicon nitride passivation and gold metallization for reliability in thermally demanding environments, with mounting base temperature rated from −20 °C to +100 °C. The module's reverse isolation exceeds −42 dB across 5–200 MHz, minimizing forward-path interference in bidirectional systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Power Gain | 35 dB typical (34.5–36 dB range), enabling single-stage amplification of weak upstream CATV return signals without cascaded stages |
| Frequency Range | 5 MHz to 200 MHz, covering full DOCSIS-compliant reverse-path spectrum including upstream bands up to 204 MHz |
| Input/Output Impedance | 75 Ω matched, ensuring minimal reflection and VSWR < 1.23 in standard CATV plant infrastructure |
| Noise Figure | 5.3 dB @ 70 MHz, preserving upstream signal-to-noise ratio for low-level return channel reception |
| Composite Triple Beat (CTB) | −74 dB @ 37 MHz (6-channel flat), meeting stringent distortion requirements for multi-channel upstream transmission |
| Total Current | 160 mA typical @ 24 V, defining thermal load and power supply sizing for headend or node deployment |
| Supply Transient Rating | Withstands up to 35 V supply transients, supporting robust operation during power rail disturbances in field equipment |
Pinout & Package
Package: SOT115J - 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. Designed for heatsink-mounting and RF-shielded enclosure integration in CATV nodes and amplifiers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input | 75 Ω coaxial input port for upstream return signal; requires DC-blocking capacitor in series |
| 2, 3, 7, 8 | Common / Ground | Four dedicated RF ground terminals providing low-inductance return paths for shielding and thermal dissipation |
| 5 | +VB Supply | 24 V DC power input with transient tolerance to 35 V; decoupling required near pin |
| 9 | RF Output | 75 Ω coaxial output driving downstream amplifier stage or trunk line; DC-isolated via internal bias tee |
Key Features
| Feature | Design Value |
|---|---|
| Excellent Linearity | CTB ≤ −74 dB and CSO ≤ −74 dB at 50 dBmV output enable 6+ channel upstream operation without distortion-limited capacity loss |
| Silicon Nitride Passivation | Protects active die against moisture and contaminants in humid outdoor CATV enclosures over 20+ year service life |
| Rugged Construction | Aluminum flange and mechanical mounting holes support vibration resistance and thermal cycling stability in pole-mounted nodes |
| Gold Metallization | Ensures bond wire reliability and corrosion resistance in high-humidity, salt-spray-prone deployment environments |
| High Reverse Isolation | s12 ≤ −42 dB prevents forward-path leakage from disrupting upstream signal integrity in bidirectional HFC architectures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar reverse-path RF amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2472ETE+ | 50 Ω I/O, 20–450 MHz bandwidth, 20 dB gain, integrated bias tee, no flange package | Designed for 50 Ω test equipment and wireless infrastructure, not CATV 75 Ω plant compatibility | Requires external impedance matching and heatsinking; suitable only for lab evaluation or non-CATV RF systems |
| LMH6552MA/NOPB | 50 Ω I/O, DC–2.8 GHz, 12 dB gain, voltage-feedback architecture, SOIC-8 package | General-purpose high-speed op-amp; lacks CATV-specific linearity specs (CTB/CSO) and 75 Ω optimization | Needs external gain-setting and matching networks; not drop-in for BGR269's reverse-path role in HFC networks |
Compared with MAX2472ETE+ and LMH6552MA/NOPB, the BGR269 delivers native 75 Ω CATV compliance, guaranteed CTB/CSO performance, and metal-flange thermal management-making it uniquely suited for production two-way cable infrastructure where signal fidelity and reliability are non-negotiable.

FAQ
What is the primary function of the BGR269 in a CATV system?
The BGR269 functions as a reverse-path RF amplifier in two-way CATV systems, boosting upstream signals from 5 MHz to 200 MHz with 35 dB gain and high linearity. Its 75 Ω I/O matching, >20 dB return loss, and −74 dB CTB performance make BGR269 essential for maintaining signal integrity in DOCSIS-compliant upstream channels.
Does the BGR269 require external biasing or DC blocking components?
No external biasing is needed-the BGR269 integrates internal bias tees for both input and output. However, an external DC-blocking capacitor is required on Pin 1 (input) to prevent damage from incoming DC offset. Pin 9 (output) is internally DC-blocked, allowing direct connection to 75 Ω coaxial lines.
What thermal management considerations apply to the BGR269?
The BGR269 uses a metal-flange SOT115J package designed for direct mounting to a heatsink. Its mounting base temperature must remain between −20 °C and +100 °C. With 160 mA total current at 24 V, thermal design must dissipate ~3.8 W; proper mechanical mounting and thermal interface material are mandatory for sustained operation.
Can the BGR269 operate with supply voltages other than 24 V?
The BGR269 is specified for normal operation at 24 V DC but can withstand transient supply voltages up to 35 V. Operation below 24 V reduces gain and linearity; operation above 24 V without transients risks exceeding limiting values. Stable 24 V regulation with local decoupling is required for compliant BGR269 performance.
Is the BGR269 suitable for automotive or safety-critical applications?
No-the BGR269 is not automotive-qualified and is explicitly intended for CATV infrastructure use only. NXP states it is neither tested nor warranted for life-critical, safety-critical, or automotive applications. Using BGR269 outside its specified CATV context voids warranty and introduces unvalidated reliability risk.
