NXP Semiconductors BGY888,112

Overview

BGY888,112 from NXP Semiconductors is a hybrid high dynamic range push-pull RF amplifier module designed for CATV line extension, operating from 40 to 860 MHz with 34 dB typical power gain at 860 MHz, 24 V DC supply, and 75 Ω input/output impedance. It delivers 60 dBmV output voltage under dim = −60 dB conditions and achieves −63.5 dB composite triple beat (CTB) distortion with 49 flat channels.

For engineers reviewing the BGY888,112 datasheet, BGY888,112 pinout, BGY888,112 application, or BGY888,112 equivalent, this page provides verified specifications, SOT115J package details, return loss performance across 40–860 MHz, noise figure ≤5 dB up to 750 MHz, and validated alternatives for CATV broadband amplification.

Technical Context

The BGY888,112 implements two cascaded cascode amplifier stages in a single hybrid module, enabling high linearity and low distortion over full CATV bandwidth. Its push-pull architecture suppresses even-order harmonics and improves CTB/CSO performance without requiring external balancing components.

It operates at 24 V DC with total current consumption of 325–340 mA and withstands transient supply voltages up to 30 V. Input and output return losses exceed 14 dB across 40–860 MHz, ensuring stable 75 Ω system matching in coaxial distribution networks.

FAQ

What is the maximum operating temperature for the BGY888,112?

The BGY888,112 has a maximum operating mounting base temperature (Tmb) of +100 °C, as specified in its limiting values table. This rating assumes proper thermal coupling of the aluminum flange to a heatsink or chassis. Operation above this temperature risks permanent degradation of gain stability and distortion performance. The BGY888,112 must be mounted using both 6-32 UNC holes to ensure reliable heat transfer at full 340 mA current draw.

Does the BGY888,112 require external biasing components?

No, the BGY888,112 is a fully self-contained hybrid amplifier module with internal biasing circuitry. It operates directly from a 24 V DC supply applied to pin 5 (+VB) and requires only input/output AC coupling capacitors and optional DC blocking on the RF ports. No external resistors, inductors, or active bias networks are needed-simplifying layout and improving repeatability in CATV production.

Can the BGY888,112 be used in 5G FR1 infrastructure applications?

The BGY888,112 is not suitable for 5G FR1 infrastructure because it is optimized for 75 Ω CATV systems (40–860 MHz), uses fixed 24 V biasing incompatible with 5G's variable supply schemes, and lacks the 5G-specific linearity metrics (EVM, ACLR) or digital predistortion support. Its SOT115J package also lacks the RF shielding and ultra-low phase noise required for massive MIMO front ends.

What is the measured CTB performance of the BGY888,112 under 129-channel loading?

Under 129-channel flat loading at 44 dBmV output level, the BGY888,112 achieves −47.5 dB (typ.) composite triple beat (CTB) distortion measured at 859.25 MHz, as documented in Table 2 of the official datasheet. This performance reflects real-world multi-carrier stress and confirms suitability for high-density digital cable deployments where spectral crowding increases intermodulation risk.

Is the BGY888,112 pin-compatible with earlier NXP CATV amplifiers like the BGY788?

No, the BGY888,112 is not pin-compatible with the BGY788. The BGY888,112 uses a 9-pin SOT115J configuration (pins 1,2,3,5,7,8,9 active), whereas the BGY788 uses a different outline and pin assignment. Substitution would require PCB redesign, including changes to ground routing, supply decoupling, and RF port placement. Always verify mechanical and electrical compatibility using the latest NXP package drawings before replacement.
