Product details
Overview
BGD714 from NXP Semiconductors is a hybrid RF power doubler amplifier module designed for CATV distribution systems, delivering 20.3 dB typical power gain at 750 MHz, 24 V DC supply operation, and 395 mA total current draw. It functions as a broadband linear driver in the 40–750 MHz band with 75 Ω input/output impedance matching.
For engineers reviewing the BGD714 datasheet, BGD714 pinout, BGD714 application, or BGD714 equivalent, this page provides verified specifications including composite triple beat (CTB) of −61 dB under 112-channel flat conditions, noise figure ≤7 dB up to 750 MHz, and SOT115J package mechanical details for thermal and layout integration.
Technical Context
The BGD714 is a silicon-based hybrid amplifier module optimized for cable television signal distribution, operating across 40–750 MHz with fixed +24 V DC bias. Its architecture delivers stable gain slope (≤1.5 dB over 45–100 MHz) and flatness (±0.15 dB at 700–750 MHz), enabling multi-channel analog/digital signal amplification without external tuning.
It features gold metallization and silicon nitride passivation for reliability in continuous-duty CATV headend and node applications. Input and output return losses exceed 19 dB across the full band, supporting low-reflection cascaded amplifier chains with minimal VSWR impact.
Key Specifications

|---|---|
| Power Gain | 21.3 dB typ. at 750 MHz - enables single-stage amplification of weak upstream/downstream signals in 750 MHz CATV trunk lines |
| Noise Figure | 7 dB max. at 750 MHz - preserves signal-to-noise ratio in high-frequency channel stacking |
| Composite Triple Beat (CTB) | −61 dB @ 112 channels, Vo = 44 dBmV, fm = 745.25 MHz - meets stringent distortion limits for DOCSIS 3.0/3.1 upstream spectral integrity |
| Total Current Consumption | 395 mA typ. @ 24 V - defines thermal load and heatsink sizing for chassis-mounted installations |
| Input Return Loss (S11) | ≥19 dB @ 650–750 MHz - minimizes reflected power in 75 Ω coaxial distribution networks |
| Supply Voltage Range | 24 V nominal, withstands transients up to 30 V - supports robust operation during power rail fluctuations in outdoor amplifiers |
| Operating Temperature | −20 °C to +100 °C mounting base - validated for sealed enclosure deployment in active node cabinets |
Pinout & Package
SOT115J is a rectangular single-ended metal-flange package with 7 gold-plated in-line leads, aluminum flange for direct thermal mounting, and two vertical 6-32 UNC mounting holes. Dimensions: 38.1 × 25.4 × 10.2 mm (L × W × H), flange thickness 2.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input | 75 Ω matched input port; connects directly to preceding stage or splitter output without external matching |
| 2, 3 | Common Ground | DC and RF ground reference; must be low-inductance connection to chassis or ground plane |
| 5 | +VB Supply | +24 V DC bias input; requires local 10 µF/100 nF decoupling near pin to suppress supply noise |
| 7, 8 | Common Ground | Secondary ground path; used with pins 2 and 3 for symmetric grounding and thermal conduction |
| 9 | RF Output | 75 Ω matched output port; drives downstream coaxial line or next amplifier stage with minimal reflection |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power doubler amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2670ETE+ | SiGe MMIC; 24 dB gain at 750 MHz; 5 V supply; 120 mA current; SOT23-6 package | Lower voltage, lower power, no flange - suited for compact indoor modules, not outdoor thermal environments | Select MAX2670ETE+ only when board space and power budget constrain use of hybrid modules like BGD714 |
| QPL9057 | GaAs pHEMT; 22 dB gain at 750 MHz; 5 V supply; 110 mA current; 2×2 mm DFN package | Higher gain but narrower bandwidth (45–1218 MHz); lacks flange cooling - limited to low-power indoor repeaters | Choose QPL9057 for cost-sensitive, low-thermal-load indoor amplifiers where 750 MHz flatness is secondary to gain density |
Compared with MAX2670ETE+ and QPL9057, the BGD714 offers superior thermal management via its aluminum flange, higher output drive capability (44–49 dBmV), and proven 750 MHz distortion performance in field-deployed CATV infrastructure - making it irreplaceable for outdoor node and trunk amplifier designs requiring long-term reliability.

FAQ
What is the maximum supply voltage rating for the BGD714?
The BGD714 has an absolute maximum supply voltage (VB) of 30 V DC, though it is designed for nominal operation at +24 V. This 6 V headroom accommodates transient surges common in outdoor CATV power supplies, ensuring continued functionality without latch-up or degradation during brief overvoltage events. The BGD714 datasheet explicitly confirms this rating under Limiting Values.
Does the BGD714 require external biasing components?
No, the BGD714 is a fully self-biased hybrid module requiring only a +24 V DC supply on pin 5 and proper RF grounding on pins 2, 3, 7, and 8. No external resistors, capacitors, or inductors are needed for DC bias setup. However, local decoupling (e.g., 10 µF tantalum + 100 nF ceramic) is recommended at the +VB pin to suppress supply noise that could modulate RF performance.
What is the thermal mounting requirement for the BGD714?
Thermal mounting is mandatory: the aluminum flange of the BGD714 must be mechanically fastened (using the two vertical 6-32 UNC holes) to a heatsink or chassis with thermal interface material. The device specifies an operating mounting base temperature range of −20 °C to +100 °C, and failure to conduct heat away from the flange will cause junction overheating and accelerated parametric drift or permanent damage.
Can the BGD714 be used in 5–42 MHz upstream applications?
Yes - the BGD714 operates from 40 MHz to 750 MHz, fully covering the 5–42 MHz upstream band. Its input return loss exceeds 23 dB at 45–80 MHz, and measured Xmod is −66 dB at 55.25 MHz under 79-channel conditions. While rated from 40 MHz, real-world upstream use at 5 MHz may require external low-frequency matching; the BGD714 itself does not guarantee performance below 40 MHz.
Is the BGD714 RoHS compliant?
The BGD714 was originally released in 2001, predating RoHS legislation. NXP's official documentation does not declare RoHS compliance for this part. For new designs requiring RoHS adherence, engineers should consult NXP's current-generation alternatives or verify compliance status through authorized distributors' traceable lot data - the BGD714 datasheet contains no RoHS statement.
