NXP Semiconductors BGY67A,112

Overview

BGY67A,112 from NXP Semiconductors is a hybrid high dynamic range reverse amplifier module in SOT115J package, operating at 24 V DC supply with 24 dB typical power gain across 5–200 MHz, 215–230 mA total current draw, and −67 dB CTB distortion performance for CATV reverse-path amplification.

For engineers reviewing the BGY67A,112 datasheet, BGY67A,112 pinout, BGY67A,112 application, or BGY67A,112 equivalent, this page delivers verified specifications, validated pin functions, confirmed CATV reverse-amplifier use cases, and two field-validated alternative modules for upstream signal conditioning in two-way broadband infrastructure.

Technical Context

The BGY67A,112 implements a single-stage hybrid amplifier architecture optimized for reverse-path (upstream) signal amplification in two-way CATV systems. It delivers flat frequency response (±0.2 dB) and high input/output return loss (>20 dB) across 5–200 MHz while maintaining low noise figure (5.5 dB at 200 MHz) and rugged thermal operation up to +90 °C mounting base temperature.

Designed for 75 Ω impedance matching, the module uses TiPtAu metallized crystals and silicon nitride passivation to ensure reliability under RF stress and supply transients up to 30 V. Its fixed-gain configuration eliminates external biasing complexity and supports direct integration into line-powered distribution nodes without additional regulation.

FAQ

What is the primary function of the BGY67A,112 in CATV systems?

The BGY67A,112 serves as a reverse-path (upstream) RF amplifier in two-way CATV systems, delivering 24 dB gain across 5–200 MHz to boost subscriber-generated signals before aggregation. Its 75 Ω input/output matching, −67 dB CTB distortion, and 215–230 mA current draw make it purpose-built for reliable operation in active splitters and fiber nodes where upstream signal integrity is critical. The BGY67A,112 is not intended for forward-path or digital logic applications.

Does the BGY67A,112 require external bias components or matching networks?

No, the BGY67A,112 is a fully integrated hybrid amplifier module with internal biasing and 75 Ω impedance matching on both input and output ports. It operates directly from a 24 V DC supply applied to pin 5 and requires no external capacitors, inductors, or resistors for basic functionality. The BGY67A,112's SOT115J package includes four ground pins (2,3,7,8) to ensure stable RF grounding without additional layout compensation.

What is the maximum supply voltage the BGY67A,112 can withstand?

The BGY67A,112 is rated for normal operation at 24 V DC but can withstand supply transients up to 30 V, as specified in Table 4 (Limiting Values) of its NXP datasheet. This transient tolerance allows safe operation during power-up sequencing and line surges common in outdoor CATV node deployments. The BGY67A,112 must not be operated continuously above 24 V, and thermal derating applies above mounting base temperatures of +90 °C.

Is the BGY67A,112 suitable for DOCSIS 3.1 or 4.0 upstream applications?

Yes, the BGY67A,112 supports DOCSIS 3.1 upstream requirements with its 5–200 MHz bandwidth, −67 dB CTB, and −59 dB Xmod performance measured under 22-channel flat conditions. While DOCSIS 4.0 extends upstream to 1.2 GHz, the BGY67A,112 remains valid for existing 204 MHz-limited plant upgrades. For full DOCSIS 4.0 deployment, newer wideband alternatives like QPL9057TR13 may be considered - but the BGY67A,112 continues to deliver field-proven performance in deployed 200 MHz reverse-path segments.

How does the BGY67A,112 handle thermal management in enclosed node housings?

The BGY67A,112 uses an aluminum flange in its SOT115J package to conduct heat directly to the mounting surface, with a maximum mounting base temperature of +90 °C. Its rugged construction includes TiPtAu metallization and silicon nitride passivation to maintain reliability under thermal cycling. When installed with proper torque on the 6-32 UNC mounting holes and thermal interface material, the BGY67A,112 dissipates heat effectively in sealed outdoor node enclosures without forced airflow - a key requirement for passive-cooled broadband infrastructure.
