Product details
Overview
BGY585A,112 from NXP Semiconductors is a hybrid push-pull RF amplifier module designed for final-stage amplification in CATV distribution systems, operating from 40 MHz to 550 MHz with 18.2 dB typical gain, 220–240 mA DC current draw at 24 V, and −59 dB CTB distortion performance at 547.25 MHz under 77-channel flat conditions.
For engineers reviewing the BGY585A,112 datasheet, BGY585A,112 pinout, BGY585A,112 application, or BGY585A,112 equivalent, this module is selected for high-linearity, low-noise broadband cable TV trunk and distribution amplifiers requiring stable 75 Ω impedance matching, rugged thermal operation up to +100 °C case temperature, and compliance with DIN45004B distortion measurement standards.
Technical Context
The BGY585A,112 implements a silicon nitride-passivated hybrid architecture with TiPtAu-metallized crystals, enabling high reliability in continuous-duty CATV headend and node applications. Its push-pull topology delivers balanced even-order distortion cancellation while maintaining ±0.2 dB frequency response flatness across 40–550 MHz.
Designed for 75 Ω system interfaces, it features input/output return loss ≥18 dB from 160–550 MHz and operates with 24 V DC supply (with transient tolerance to 30 V). The module's 220 mA typical current draw and 8 dB noise figure at 550 MHz support cascaded amplifier chain design with controlled noise accumulation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BGY586A,112 | Same SOT115J package; 40–450 MHz bandwidth; 7 dB noise figure at 450 MHz; −61 dB CTB at 445.25 MHz | Better noise performance and distortion in sub-450 MHz legacy CATV bands; reduced high-end gain roll-off | Select when optimizing for analog video or early DOCSIS deployments below 550 MHz |
| UFL1200T | Surface-mount GaAs MMIC; 50–1200 MHz; 15 dB gain; 4.5 dB noise figure; requires external biasing and matching | Wider bandwidth but lower linearity (−52 dB CTB); no integrated thermal flange; higher layout sensitivity | Choose for compact PCB-based designs where size outweighs linearity and thermal robustness requirements |
Compared with BGY585A,112, the BGY586A,112 trades upper-bandwidth coverage for improved noise and distortion below 450 MHz, while the UFL1200T offers broader frequency range at the cost of discrete bias network design effort and reduced ruggedness in outdoor thermal environments.

FAQ
What is the maximum case temperature rating for the BGY585A,112?
The BGY585A,112 is rated for continuous operation at a case temperature (Tcase) of −20 °C to +100 °C. This specification allows deployment in unventilated outdoor cabinets and pole-mounted nodes without forced cooling, provided thermal interface resistance and heatsink design maintain junction temperature within safe limits per the device's thermal resistance characteristics.
Does the BGY585A,112 require external bias sequencing or startup control?
No, the BGY585A,112 operates with a single 24 V DC supply applied to pin 5 (+VB) and does not require bias sequencing, enable pins, or startup timing control. It draws 220–240 mA continuously and is designed for immediate RF amplification upon power application, making it suitable for always-on CATV infrastructure.
Can the BGY585A,112 be used in 50 Ω systems such as wireless infrastructure?
The BGY585A,112 is characterized and optimized for 75 Ω CATV systems (ZS = ZL = 75 Ω), with input/output return loss specified only under that condition. Using it in 50 Ω systems would degrade match, increase VSWR, and impair distortion performance; it is not recommended outside its intended 75 Ω impedance context.
What is the meaning of "slope cable equivalent" (SL) in the BGY585A,112 datasheet?
"Slope cable equivalent" (SL) quantifies the gain tilt across frequency - for the BGY585A,112, SL is 0.5–2 dB over 40–550 MHz. This value indicates how much additional equalization (e.g., via passive slope-compensating pads) may be needed to achieve flat response in long coaxial runs where cable loss increases with frequency.
Is the BGY585A,112 automotive qualified?
No, the BGY585A,112 is not automotive qualified. Per NXP's legal disclaimers, it is intended exclusively for CATV infrastructure use and has not been tested or certified to AEC-Q100 or other automotive reliability standards. Its qualification scope covers commercial/industrial temperature and reliability requirements for fixed broadband networks only.
