Product details
Overview
BGS67A,112 from NXP Semiconductors (formerly Philips Semiconductors) is a hybrid high dynamic range reverse amplifier module designed for CATV return-path amplification. It delivers 25.5 dB power gain at 10 MHz, operates from a 12 V supply with 75–95 mA total current draw, and supports 5–65 MHz bandwidth with ±0.2 dB flatness and 3.5 dB noise figure at 65 MHz.
For engineers reviewing the BGS67A,112 datasheet, BGS67A,112 pinout, BGS67A,112 application, or BGS67A,112 equivalent, key selection criteria include its SOT567A leadless package, dual +VB and common terminals, rugged silicon nitride passivation, and verified CTB (−64 dB) and Xmod (−54 dB) performance in multi-channel CATV systems.
Technical Context
The BGS67A,112 functions as a broadband reverse-path amplifier in two-way cable networks, optimized for 5–65 MHz upstream signal conditioning. Its hybrid construction integrates active and passive elements to achieve excellent linearity (CTB ≤ −64 dB, Xmod ≤ −54 dB) and low noise (NF = 3.5 dB), while maintaining input/output return loss ≥20 dB across the band.
It employs gold metallization and silicon nitride passivation for reliability under thermal cycling and humidity stress. The module withstands supply transients up to 30 V despite nominal 12 V operation, and requires ESD-handling precautions per IEC 61340-5-1 due to sensitivity to electrostatic discharge.
Key Specifications

|---|---|---|---|
| MAX2472EUT+T | 50 Ω system, 20–450 MHz bandwidth, 15.5 dB gain, higher NF (4.5 dB), SO-8 package | Designed for general-purpose RF gain blocks, not optimized for 75 Ω CATV return-path linearity or CTB | Use only where 75 Ω impedance matching and CATV-specific distortion specs are not required |
| QPL9057TR13 | 75 Ω, 5–65 MHz, 23 dB gain, −62 dB CTB, 4.2 dB NF, 3×3 mm QFN | Lower gain and higher noise than BGS67A,112; lacks dual +VB pins and ruggedized passivation | Acceptable for cost-sensitive, lower-performance return-path stages where thermal robustness is secondary |

FAQ
What is the operating supply voltage range for the BGS67A,112?
The BGS67A,112 operates nominally at 12 V DC but is rated to withstand supply transients up to 30 V without damage. Total current consumption ranges from 75 mA to 95 mA at 12 V, and the device requires proper decoupling on both +VB pins (Pins 4 and 8) to ensure stable RF performance and thermal management.
Does the BGS67A,112 require external biasing or tuning components?
No, the BGS67A,112 is a fully self-contained hybrid amplifier module with internal biasing and impedance matching. It requires only DC blocking capacitors (typically 100 pF) on input and output, plus 10 µF/100 nF parallel decoupling on each +VB pin. No external inductors, resistors, or trimmers are needed for standard 75 Ω CATV operation.
How does the BGS67A,112 handle thermal management in enclosed node housings?
The BGS67A,112 uses a thermally enhanced SOT567A package with an exposed metal pad (Z6/Z7) that must be soldered to a dedicated copper thermal land on the PCB. Mounting base temperature is rated from −20 °C to +100 °C, and proper thermal vias beneath the pad reduce junction-to-ambient resistance, enabling reliable operation in sealed outdoor enclosures without forced airflow.
Is the BGS67A,112 compatible with DOCSIS 4.0 upstream channel bonding?
The BGS67A,112 supports the 5–65 MHz frequency band used in DOCSIS 3.0 and earlier upstream profiles. While it does not extend to the extended upstream spectrum (up to 204 MHz) required for DOCSIS 4.0 channel bonding, its −64 dB CTB and ±0.2 dB flatness remain fully compliant for legacy and current-generation upstream deployments in existing HFC plants.
What ESD precautions are required when handling the BGS67A,112?
The BGS67A,112 is highly sensitive to electrostatic discharge (ESD), per IEC 61340-5-1 Class 1A (≤250 V). Handlers must use grounded wrist straps, ESD-safe work surfaces, conductive foam storage, and ionized air environments. PCB assembly requires ESD-safe soldering irons and automated placement equipment with static-dissipative nozzles to prevent latent damage to the hybrid die.
