Product details
Overview
BGD502,112 from NXP Semiconductors is a hybrid CATV power doubler amplifier module operating from 40 to 550 MHz with 18.5 dB typical power gain at 550 MHz, 415–435 mA DC current draw at 24 V supply, 75 Ω input/output impedance, and −65 dB CTB distortion performance in 77-channel flat systems. It serves as a broadband RF driver stage in cable television trunk and distribution amplifiers.
For engineers reviewing the BGD502,112 datasheet, BGD502,112 pinout, BGD502,112 application, or BGD502,112 equivalent, key selection criteria include its SOT115J flanged package, 9-pin configuration with common ground terminals, 550 MHz bandwidth, low noise figure (8 dB at 550 MHz), and ruggedized construction for outdoor plant reliability.
Technical Context
The BGD502,112 is a silicon-based hybrid amplifier module optimized for linear broadband amplification in 75 Ω CATV infrastructure. Its architecture delivers flat frequency response (±0.3 dB over 40–550 MHz), high return loss (>18 dB across full band), and phase stability (+135° to +225° at 50 MHz) to support multi-carrier signal integrity.
It operates exclusively at 24 V DC with transient tolerance up to 30 V, features TiPtAu metallized crystals for reliability, and uses silicon nitride passivation for environmental robustness. Thermal management relies on aluminum flange mounting with two vertical 6-32 UNC holes.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar broadband CATV amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2109ETL+ | Monolithic SiGe IC; 40–1000 MHz range; 17.5 dB gain; requires external biasing and matching; 5 V supply | Designed for compact, low-power active splitters and mini-nodes-not rated for outdoor trunk use | Select when board space is constrained and system operates below 1000 MHz with regulated 5 V supply |
| ADL5535ACPZ-R7 | Monolithic GaAs pHEMT; 20–1000 MHz; 20 dB gain; 5 V supply; higher NF (4.5 dB); no flanged package | Targeted at lab instrumentation and point-to-point wireless links-not qualified for continuous 24 V CATV plant operation | Select when ultra-low noise and wideband coverage beyond 550 MHz are prioritized over mechanical ruggedness and 75 Ω system integration |
Compared with MAX2109ETL+ and ADL5535ACPZ-R7, the BGD502,112 offers proven field reliability in 24 V outdoor CATV plants, integrated 75 Ω matching, flanged thermal management, and distortion performance validated per DIN45004B-making it uniquely suited for legacy and hybrid fiber-coax infrastructure where mechanical durability and system-level linearity are non-negotiable.

FAQ
What is the maximum RF input voltage rating for the BGD502,112?
The BGD502,112 has a maximum RF input voltage rating of 65 dBmV, as specified in the Limiting Values table. This corresponds to approximately 1.99 Vpp across a 75 Ω load. Exceeding this level risks compression or damage to the input stage, especially under multi-tone conditions. The device is designed for standard CATV signal levels and should not be driven beyond this limit even during transient events.
Does the BGD502,112 require external biasing components?
No, the BGD502,112 does not require external biasing components. It is a fully self-contained hybrid module with internal bias networks optimized for 24 V DC operation. Only a local 10 µF tantalum and 100 nF ceramic decoupling capacitor at pin 5 (+VB) and proper RF grounding via pins 2, 3, 7, and 8 are needed. No external resistors, capacitors, or inductors are required for basic operation per the datasheet design guidelines.
Can the BGD502,112 operate at frequencies above 550 MHz?
No, the BGD502,112 is characterized and guaranteed only up to 550 MHz. While some gain may persist beyond that frequency, specifications such as power gain, CTB, CSO, and return loss are not validated above 550 MHz. Table 1 explicitly defines performance over 40–550 MHz, and the device is intended for legacy CATV systems-not DOCSIS 3.1/4.0 extended spectrum applications requiring operation beyond 1 GHz.
What is the thermal resistance (RθJA) of the BGD502,112?
The datasheet does not specify junction-to-ambient thermal resistance (RθJA) for the BGD502,112. Instead, it defines operating mounting base temperature (Tmb) limits of −20 °C to +100 °C and specifies thermal performance through total current consumption (415–435 mA at 24 V) and flange-mounting requirements. Effective thermal design requires bolting the aluminum flange to a heatsink or chassis with thermal compound, using both 6-32 UNC mounting holes, and maintaining ambient airflow per CATV cabinet standards.
Is the BGD502,112 pin-compatible with other SOT115J amplifiers like the BGD501?
No, the BGD502,112 is not confirmed pin-compatible with the BGD501 or other SOT115J variants. Although both use the SOT115J package, the BGD501 datasheet (if available) would need to confirm identical pin functions. The BGD502,112 pinning assigns pin 1 as input, pins 2/3 and 7/8 as grounds, pin 5 as +VB, and pin 9 as output - but alternate configurations exist within the same outline. Substitution requires verification of functional pin mapping and electrical compatibility, not just package footprint.
