Product details
Overview
BGE788,112 from NXP Semiconductors is a hybrid high dynamic range push-pull RF amplifier module in SOT115J package, operating at 24 V DC supply with 34 dB gain at 750 MHz, 7 dB noise figure, and 290–320 mA total DC current consumption. It delivers CATV line extension in 40–750 MHz bandwidth with ±0.5 dB flatness and −49 dB CTB distortion performance.
For engineers reviewing the BGE788,112 datasheet, BGE788,112 pinout, BGE788,112 application, or BGE788,112 equivalent, this module supports critical RF signal chain design in broadband cable infrastructure where linearity, noise, return loss, and thermal stability under 24 V operation are essential selection criteria.
Technical Context
The BGE788,112 integrates two cascaded cascode amplifier stages optimized for 75 Ω impedance systems. Its architecture enables high gain with low intermodulation distortion across 40–750 MHz while maintaining input/output return loss ≥14 dB up to 750 MHz.
It operates exclusively at 24 V DC (with transient tolerance to 30 V), uses gold-plated in-line leads on an aluminum flange for thermal dissipation, and requires electrostatic discharge (ESD) handling precautions during assembly due to its sensitivity.
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 |
|---|---|---|---|
| MAX2130ETJ+ (Maxim Integrated) | 5 V operation, 30 dB gain, 1.2 GHz bandwidth; integrated bias control and shutdown | Designed for portable broadband receivers, not CATV infrastructure | Select only for low-voltage, wideband receiver front-end use - not suitable for 24 V CATV line extension |
| QPL9547 (Qorvo) | 5 V supply, 22 dB gain, 40–4000 MHz; GaAs pHEMT, no flange package | Optimized for wireless infrastructure and small-cell base stations | Use where ultra-wideband coverage and compact SMT footprint are prioritized over CATV-specific linearity and thermal mass |
Compared with MAX2130ETJ+ and QPL9547, the BGE788,112 offers uniquely high 24 V supply compatibility, aluminum-flange thermal management, and CATV-validated distortion performance (−49 dB CTB, −52 dB CSO) in the 40–750 MHz band - making it irreplaceable for fixed broadband infrastructure upgrades requiring proven field reliability.

FAQ
What is the maximum supply voltage the BGE788,112 can withstand?
The BGE788,112 is rated for 24 V DC nominal operation but can withstand supply transients up to 30 V per its Absolute Maximum Ratings table. Continuous operation above 25 V is not recommended, and sustained 30 V exposure may impact long-term reliability. The BGE788,112 must be operated within 24 V ±10 % for guaranteed specification compliance.
Does the BGE788,112 require external bias circuitry?
No, the BGE788,112 is a fully self-biased hybrid module with internal cascode stage biasing. It requires only a single 24 V DC supply applied to pin 5 (+VB) and proper RF decoupling. No external resistors, capacitors, or bias tees are needed for basic operation - simplifying layout and reducing bill-of-materials count for the BGE788,112.
What is the thermal mounting requirement for the BGE788,112?
The BGE788,112 uses an aluminum flange (SOT115J package) designed for direct mechanical and thermal attachment to a heatsink or chassis. Mounting base temperature must remain ≤100 °C, and thermal interface material with ≤0.5 °C·in²/W resistance is recommended. The four ground pins (2, 3, 7, 8) also serve as thermal conduction paths, so PCB copper pour under the flange is essential for the BGE788,112.
Is the BGE788,112 suitable for DOCSIS 4.0 deployments?
The BGE788,112 is characterized up to 750 MHz and validated for DOCSIS 3.1 upstream and downstream performance, but it is not specified for DOCSIS 4.0's extended 1.2 GHz or 1.8 GHz bands. Its gain rolls off beyond 750 MHz, and distortion metrics are not published above that frequency. For DOCSIS 4.0, newer wideband amplifiers should be evaluated - the BGE788,112 remains optimal for legacy and mid-band upgrades.
How does the BGE788,112 handle ESD during handling and assembly?
The BGE788,112 is highly sensitive to electrostatic discharge (ESD), as explicitly noted in its datasheet caution statement. It must be handled using Class 1A ESD controls: grounded wrist straps, conductive foam storage, ionized air workstations, and ESD-safe packaging. PCB assembly requires ESD-safe soldering irons and verified grounding of reflow ovens - failure to observe these precautions risks immediate latent or catastrophic failure of the BGE788,112.
