Product details
Overview
BGE788C from NXP Semiconductors is a hybrid high dynamic range RF amplifier module designed for CATV line extension, operating at 24 V DC in a SOT115J package with cascode-cascaded push-pull architecture. It delivers 33.5 dB gain at 750 MHz, supports 40–750 MHz bandwidth, achieves −49 dB CTB and −52 dB CSO distortion performance, and targets single-module 75 Ω coaxial distribution systems.
For engineers reviewing the BGE788C datasheet, BGE788C pinout, BGE788C application, or BGE788C equivalent, this page provides verified specifications including gain flatness (±0.6 dB), input/output return loss (≥14 dB), noise figure (8 dB), total current draw (285–325 mA), and thermal mounting base limits (−20 °C to +100 °C) critical for broadband RF system design and replacement validation.
Technical Context
The BGE788C implements a two-stage cascode configuration with push-pull topology to maximize linearity and minimize even-order distortion-essential for multi-channel CATV signal integrity. Its 75 Ω impedance-matched I/O and optimized biasing enable stable operation across 40–750 MHz without external matching networks.
Designed for fixed 24 V DC supply (with transient tolerance up to 30 V), the module integrates internal thermal management via aluminum flange mounting and requires controlled baseplate temperature (Tmb) between −20 °C and +100 °C to maintain specified CTB/CSO and gain flatness performance.

Pinout & Package
SOT115J is a rectangular single-ended hybrid module with aluminum flange, 2 vertical and 2 horizontal 6-32 UNC mounting holes, and 7 gold-plated in-line leads. Thermal and mechanical stability is achieved via direct flange-to-heatsink mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input | 75 Ω matched input port; connects directly to upstream coaxial feed without external coupling or DC blocking. |
| 2, 3, 7, 8 | Common (Ground) | Four dedicated RF ground terminals ensure low-inductance return paths and minimize ground loop distortion. |
| 5 | +VB Supply | 24 V DC power input; withstands transients up to 30 V; requires local 10 µF/100 nF decoupling per layout guidelines. |
| 9 | RF Output | 75 Ω matched output port; drives downstream coaxial trunk or drop cable with minimal insertion loss. |
Key Features
| Feature | Design Value |
|---|---|
| Push-pull cascode architecture | Suppresses even-order harmonics and improves third-order intercept point (IP3), enabling >110-channel operation. |
| 75 Ω impedance matching | Eliminates need for external matching components in standard CATV plant, reducing bill-of-materials and assembly cost. |
| Slope compensation (0.3–2.3 dB) | Compensates for frequency-dependent cable loss; allows precise tilt control in line extender configurations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar broadband RF amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2550–001 | Higher gain (36 dB), narrower bandwidth (45–1000 MHz), higher NF (9.5 dB), uses 12 V supply. | Optimized for compact MDU amplifiers requiring wider upper-band coverage but less upstream sensitivity. | Select when 12 V infrastructure exists and >750 MHz edge coverage is required; verify thermal derating at 325 mA. |
| QPL9057 | Monolithic GaAs pHEMT, 32 dB gain at 750 MHz, lower current (220 mA), no flange mounting, 5 V supply. | Targeted for space-constrained active splitters or low-power node designs-not suitable for high-power line extension. | Choose for PCB-mounted, non-flanged applications with strict power budget; not a drop-in replacement due to different thermal and pinout requirements. |
Compared with MAX2550–001 and QPL9057, the BGE788C uniquely combines 24 V flange-mount thermal robustness, 75 Ω system-native I/O, and −49 dB CTB performance in a single module-making it irreplaceable for high-reliability CATV trunk amplification where distortion and thermal stability are non-negotiable.

FAQ
What is the maximum supply voltage transient the BGE788C can withstand?
The BGE788C is rated for normal operation at 24 V DC but can withstand supply transients up to 30 V without damage, as confirmed in Table 1 and Table 4 of the official NXP datasheet. This transient tolerance supports robust operation during power-up sequencing and line surges in outdoor CATV plant environments. Always limit steady-state VB to 24 V to maintain specified gain, distortion, and thermal performance for the BGE788C.
Does the BGE788C require external biasing or matching components?
No, the BGE788C integrates internal biasing and is fully 75 Ω impedance-matched at both input and output. The datasheet confirms operation with no external matching networks required across 40–750 MHz. Only local decoupling (10 µF + 100 nF) on the +VB pin (Pin 5) is mandated. This simplifies layout and ensures repeatable performance for the BGE788C in production CATV amplifier modules.
How is thermal management implemented for the BGE788C?
The BGE788C uses an aluminum flange (SOT115J package) for direct conduction cooling. Mounting base temperature (Tmb) must be maintained between −20 °C and +100 °C per Table 4. Thermal vias and heatsink contact area must cover the full flange footprint. Exceeding +100 °C Tmb degrades CTB/CSO and accelerates long-term drift-critical for sustained reliability of the BGE788C in sealed node enclosures.
What does "slope cable equivalent" mean for the BGE788C?
"Slope cable equivalent" (0.3–2.3 dB, Table 5) quantifies the BGE788C's built-in frequency-dependent gain tilt, simulating coaxial cable loss slope to pre-compensate for downstream attenuation. This enables flat composite response over long trunk runs without external tilt networks-directly supporting standardized CATV line extender configurations using the BGE788C.
Is the BGE788C suitable for DOCSIS 4.0 or full-duplex upstream applications?
The BGE788C supports 40–750 MHz operation and meets SCTE 47-2015 distortion specs for 110-channel systems, but it is not characterized for DOCSIS 4.0's extended upstream band (up to 204 MHz) or full-duplex operation. Its 50 MHz noise figure and 750 MHz gain roll-off make it appropriate for legacy and DOCSIS 3.1 deployments-but not for next-gen full-duplex or >1 GHz applications requiring the BGE788C's successor devices.
