NXP Semiconductors BGY887B,112

Overview

BGY887B,112 from NXP Semiconductors is a hybrid CATV amplifier module in SOT115J package, operating at 24 V DC supply with 29 dB power gain at 860 MHz, <±0.5 dB flatness across 40–860 MHz, and −60 dB CTB distortion under 49-channel flat conditions - deployed as a single-module line extender in broadband cable distribution systems.

For engineers reviewing the BGY887B,112 datasheet, BGY887B,112 pinout, BGY887B,112 application, or BGY887B,112 equivalent, this high-linearity 75 Ω RF amplifier supports critical design tasks including cascade gain budgeting, return loss validation, noise figure allocation, and multi-channel distortion compliance for DOCSIS-compliant headend and node amplification.

Technical Context

The BGY887B,112 integrates two cascaded cascode amplifier stages optimized for 75 Ω CATV infrastructure, delivering stable gain and low noise across 40–860 MHz while maintaining input/output return loss ≥14 dB up to 860 MHz. Its hybrid construction enables thermal stability at mounting base temperatures up to +100 °C.

Designed for fixed 24 V DC operation (with transient tolerance to 30 V), the module draws ≤340 mA total current and achieves noise figure ≤5 dB at 50 MHz - enabling high-sensitivity upstream signal recovery in distributed amplification nodes.

FAQ

What is the operating supply voltage range for the BGY887B,112?

The BGY887B,112 operates at a nominal 24 V DC supply and is rated to withstand transients up to 30 V. Total DC current consumption remains ≤340 mA under all specified conditions, making it compatible with standard CATV power insertion systems. The BGY887B,112 does not support dual-supply or adjustable bias configurations.

Does the BGY887B,112 require external matching components for 75 Ω systems?

No, the BGY887B,112 features internally matched 75 Ω input and output ports, verified by S11 and S22 ≥14 dB across 640–860 MHz. No external baluns, transformers, or tuning stubs are needed for standard coaxial CATV plant integration. The BGY887B,112 is designed for direct drop-in use in 75 Ω line extender modules.

What is the maximum ambient temperature rating for BGY887B,112 in continuous operation?

The BGY887B,112 is rated for operating mounting base temperature (Tmb) from −20 °C to +100 °C. Its SOT115J metal flange allows direct thermal coupling to heatsinks, enabling reliable continuous operation in sealed outdoor amplifier housings without forced air cooling. The BGY887B,112 must be mounted to a thermally conductive surface per datasheet mechanical guidelines.

How does BGY887B,112 perform on composite distortion metrics at full bandwidth?

At 40–860 MHz with 49 flat channels and 44 dBmV output level, the BGY887B,112 achieves CTB ≤−60 dB, Xmod ≤−60 dB, and CSO ≤−60 dB - meeting stringent FCC Part 76 requirements for multi-stage cascades. These values are measured per DIN45004B methodology and confirmed in Table 1 of the official datasheet. The BGY887B,112 maintains this performance without external predistortion circuitry.

Is BGY887B,112 pin-compatible with earlier BGY887 variants like BGY887A?

Yes, the BGY887B,112 shares identical SOT115J pinout, mechanical outline, and electrical specifications with BGY887A and BGY887 - all feature pins 1 (input), 2/3/7/8 (common), 5 (+VB), and 9 (output). The "B" suffix denotes an updated characterization revision, not a functional or mechanical change. The BGY887B,112 may be used as a direct replacement in existing BGY887A-based designs.
