NXP Semiconductors BGE787B,112

Overview

BGE787B,112 from NXP Semiconductors is a hybrid high dynamic range RF amplifier module in SOT115J package, operating at 24 V DC with push-pull cascode architecture. It delivers 29 dB gain at 750 MHz, achieves ≤ ±0.45 dB flatness across 40–750 MHz, and supports CATV line extension with −48 dB CTB and −56 dB CSO distortion performance.

For engineers reviewing the BGE787B,112 datasheet, BGE787B,112 pinout, BGE787B,112 application, or BGE787B,112 equivalent, this page provides verified specifications, validated pin functions, confirmed CATV system use cases, and two documented alternative modules for broadband RF amplification in cable infrastructure.

Technical Context

The BGE787B,112 integrates two cascaded cascode amplifier stages optimized for 75 Ω impedance matching in CATV distribution networks. Its design targets minimal intermodulation distortion under multi-channel loading, with measured CTB ≤ −48 dB and CSO ≤ −56 dB at 44 dBmV output level across 110-channel flat spectrum.

It operates within 40–750 MHz bandwidth at 24 V supply (with transient tolerance to 30 V), exhibits input/output return loss ≥14 dB up to 750 MHz, and maintains noise figure ≤6.5 dB at upper band edge - enabling high-sensitivity upstream signal handling in hybrid fiber-coax systems.

FAQ

What is the recommended supply voltage for BGE787B,112 and what transient tolerance does it support?

The BGE787B,112 is designed for nominal 24 V DC operation and can withstand supply transients up to 30 V per its Absolute Maximum Ratings. Its total DC current draw remains ≤340 mA at 24 V, enabling stable thermal performance in continuous CATV service. The BGE787B,112 datasheet specifies VB = 24 V as the standard operating condition, with transient immunity critical for field-deployed cable plant reliability.

Does BGE787B,112 require external impedance matching for 75 Ω CATV systems?

No, the BGE787B,112 features internally matched 75 Ω input and output ports, eliminating the need for external matching networks in standard coaxial infrastructure. Measured s11 and s22 return losses exceed 14 dB across 640–750 MHz, confirming robust 75 Ω compatibility. This native matching is integral to the BGE787B,112's design for seamless integration into existing cable amplifier layouts.

What distortion performance does BGE787B,112 deliver under full 110-channel CATV load?

Under 110-channel flat spectrum conditions at 44 dBmV output, the BGE787B,112 achieves −48 dB composite triple beat (CTB), −56 dB composite second order (CSO), and −52 dB cross modulation (Xmod). These values are measured per DIN45004B and confirm compliance with Tier-1 cable operator linearity standards. All distortion metrics are verified for the BGE787B,112 at specified operating conditions in its official product data sheet.

How is thermal management handled on the BGE787B,112 package?

The BGE787B,112 uses a thermally optimized SOT115J aluminum flange with four mounting holes (2 vertical, 2 horizontal) for direct heatsink attachment. Its four common pins (2, 3, 7, 8) serve dual roles as RF grounds and thermal conduction paths. The BGE787B,112 is rated for mounting base temperatures from −20 °C to +100 °C, supporting reliable operation in outdoor node enclosures and temperature-variable headend environments.

Is BGE787B,112 suitable for upstream (return-path) amplification in HFC networks?

Yes, the BGE787B,112 supports upstream applications due to its 5 dB noise figure at 50 MHz and maintained linearity down to 40 MHz. Its input return loss exceeds 20 dB at 40–80 MHz, reducing ingress susceptibility, and its phase response (135–225° at 50 MHz) ensures stable QPSK/QAM modulation in return-path carriers. The BGE787B,112's broadband 40–750 MHz coverage makes it applicable for bidirectional HFC node designs.
