Product details
Overview
BGY588N from NXP Semiconductors is a hybrid push-pull RF amplifier module designed for CATV line-extender applications in the 40–550 MHz band, delivering 34.5 dB typical power gain at 50 MHz and 35.5 dB at 550 MHz, with 325 mA total DC current draw at 24 V supply and ±0.3 dB frequency response flatness.
For engineers reviewing the BGY588N datasheet, BGY588N pinout, BGY588N application, or BGY588N equivalent, key selection criteria include its SOT115J package with gold-plated in-line leads, rugged TiPtAu metallization, -57 dB CTB distortion performance, and suitability for 77-channel flat CATV distribution systems requiring high linearity and low noise figure (5–6 dB).
Technical Context
The BGY588N implements a silicon-based hybrid push-pull architecture optimized for broadband cable TV signal amplification, operating exclusively at 24 V DC with transient tolerance up to 30 V. Its input and output return losses exceed 18 dB across 40–550 MHz, ensuring stable 75 Ω system impedance matching without external tuning networks.
It delivers specified composite distortion performance--57 dB CTB, -59 dB Xmod, and -62 dB CSO-at 44 dBmV output level across 77 flat channels, confirming compliance with DIN45004B measurement standards for multi-carrier CATV line extenders.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2671EUT+T | 3.3 V operation, 400–2500 MHz range, 15.5 dB gain, GaAs pHEMT process | Designed for wireless infrastructure, not CATV; lacks 75 Ω matching and CTB validation | Select only for non-CATV broadband RF gain where low voltage and wideband coverage outweigh linearity needs |
| QPL9057TR13 | 5 V supply, 400–4200 MHz, 20 dB gain, integrated active bias, SOT-89 package | Optimized for 5G small cells; no 75 Ω interface, no CATV distortion specs, smaller thermal mass | Prefer for space-constrained wireless front-ends; avoid in CATV due to missing DIN45004B validation and insufficient output drive |
Compared with MAX2671EUT+T and QPL9057TR13, the BGY588N uniquely combines 24 V CATV-grade power handling, 75 Ω system impedance, -57 dB CTB, and SOT115J flange-mounting-making it irreplaceable for legacy and new-build HFC line extender hardware where regulatory distortion limits and thermal reliability are mandatory.

FAQ
What is the recommended supply voltage for stable operation of the BGY588N?
The BGY588N is designed for nominal 24 V DC operation, with tested functionality up to 30 V transients. Operating below 22 V reduces gain and increases distortion; above 26 V risks exceeding absolute maximum ratings. The BGY588N datasheet specifies 325 mA typical current draw at 24 V, defining minimum PSU capacity for thermal and voltage regulation stability in field-deployed CATV nodes.
Does the BGY588N require external input/output DC blocking capacitors?
No, the BGY588N features internally DC-blocked RF ports. Pin 1 (input) and Pin 9 (output) are AC-coupled within the hybrid module, allowing direct connection to 75 Ω CATV transmission lines without external capacitors. This simplifies PCB layout and eliminates insertion loss and resonance risks associated with discrete blocking components in the BGY588N signal path.
How does the BGY588N achieve its -57 dB CTB performance?
The BGY588N achieves -57 dB composite triple beat through its push-pull transistor pairing, precise bias point control, and monolithic hybrid construction minimizing parasitic coupling. Measured per DIN45004B at 547.25 MHz with 77 flat channels at 44 dBmV output, this CTB value reflects intrinsic linearity-not external feedback or post-compensation-making the BGY588N suitable for unattended, maintenance-free CATV line extenders.
Can the BGY588N be used in 5G or wireless infrastructure applications?
The BGY588N is not recommended for 5G or wireless infrastructure use. It operates only in the 40–550 MHz CATV band, uses 75 Ω impedance (not 50 Ω), lacks S-parameter data beyond 550 MHz, and has no EVM or ACLR validation. Its thermal design and distortion metrics target HFC networks-not cellular base stations-so substituting the BGY588N in wireless designs risks noncompliance and degraded RF performance.
What is the thermal resistance and heatsinking requirement for the BGY588N?
The BGY588N uses an aluminum flange in SOT115J packaging with direct-mount thermal interface. Its junction-to-case thermal resistance is ≤1.2 °C/W, requiring a heatsink capable of dissipating ≥8.3 W (24 V × 0.34 A max). Mounting must use both vertical 6-32 UNC screws with thermal compound; failure to heatsink causes Tmb exceedance beyond +100 °C, triggering permanent gain drift and distortion rise in the BGY588N.
