Product details
Overview
BGD804,112 from NXP Semiconductors is a hybrid RF power doubler amplifier module designed for CATV distribution systems, delivering 20 dB small-signal gain at 860 MHz with 75 Ω input/output impedance, 24 V DC supply operation, and total DC current draw ≤410 mA. It supports 40–860 MHz bandwidth with ±0.5 dB flatness and achieves −64 dB CTB distortion at 49-channel flat test conditions.
For engineers reviewing the BGD804,112 datasheet, BGD804,112 pinout, BGD804,112 application, or BGD804,112 equivalent, this page provides verified pin configuration, real-world distortion metrics (CTB/Xmod/CSO), thermal operating limits (−20 to +100 °C mounting base), SOT115J package dimensions, and direct alternatives validated for CATV line extender and node amplifier use.
Technical Context
The BGD804,112 implements a broadband hybrid amplifier architecture optimized for cable television signal distribution, featuring silicon nitride passivation and gold metallization for reliability in continuous 24 V DC operation. Its design targets minimal slope (0.2–2 dB cable-equivalent) and high return loss (>14 dB input/output up to 860 MHz) across the full 40–860 MHz band.
It operates with 75 Ω system impedance matching, delivers +60 dBmV typical output voltage under dimmed conditions, and maintains noise figure ≤7.5 dB at 860 MHz while supporting transient supply tolerance up to 30 V - critical for field-deployed CATV infrastructure where voltage regulation varies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Power gain | 20 dB at 860 MHz - ensures sufficient signal boost for multi-drop coaxial distribution without cascaded amplification stages. |
| Bandwidth | 40–860 MHz - fully covers DOCSIS 3.1/4.0 upstream/downstream spectrum and legacy analog TV channels. |
| Output voltage | +60 dBmV (typ.) - meets CATV node output level requirements for 75 Ω systems with headroom for cable loss compensation. |
| Composite triple beat (CTB) | −64 dB (49-channel flat) - enables high-channel-count digital QAM transmission with low intermodulation interference. |
| Noise figure | 7.5 dB max at 860 MHz - preserves signal-to-noise ratio in downstream paths where upstream noise ingress is minimized. |
| Total DC current | 395–410 mA at 24 V - defines thermal load and power supply sizing for outdoor node enclosures. |
| Input/output impedance | 75 Ω - matches standard CATV coaxial infrastructure, eliminating need for external matching networks. |
Pinout & Package
SOT115J package: rectangular single-ended metal flange with 7 gold-plated in-line leads, 2 vertical 6-32 UNC mounting holes, aluminum construction, and specified outline dimensions (L = 38.1 mm, W = 25.4 mm, H = 10.2 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF input | 75 Ω matched input port for upstream/downstream signal injection; requires DC blocking if biased externally. |
| 2 | Common (ground) | RF and DC ground reference for input stage; must be low-inductance connection to chassis ground. |
| 3 | Common (ground) | Secondary ground terminal for thermal and RF stability; ties to flange and heatsink interface. |
| 5 | +VB (supply) | 24 V DC power input; withstands transients up to 30 V; requires local 10 µF/100 nF decoupling per datasheet layout guidance. |
| 7 | Common (ground) | Ground return for output stage and internal bias network; critical for return loss performance above 640 MHz. |
| 8 | Common (ground) | Additional ground path for thermal dissipation and EMI suppression; connects directly to flange. |
| 9 | RF output | 75 Ω matched output driving coaxial trunk or drop cable; rated for continuous +60 dBmV into 75 Ω load. |
Key Features
| Feature | Design Value |
|---|---|
| Excellent linearity | −64 dB CTB and −65.5 dB Xmod at 49-channel flat test - enables dense QAM modulation without adjacent-channel interference. |
| Extremely low noise | 4.5 dB noise figure at 50 MHz, rising to 7.5 dB at 860 MHz - preserves SNR in first-stage amplification of weak upstream signals. |
| Silicon nitride passivation | Hermetic protection against moisture and contaminants - ensures long-term reliability in humid outdoor node enclosures. |
| Rugged construction | Aluminum flange with 2×6-32 UNC mounting and gold-plated leads - supports mechanical shock/vibration resistance in pole-mounted deployments. |
| Gold metallization | Corrosion-resistant interconnects and bond wires - prevents contact degradation over 15+ year field life in temperature-cycled environments. |

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 |
|---|---|---|---|
| MAX2108ETJ+ | Monolithic SiGe IC (not hybrid); 17 dB gain at 860 MHz; 5 V supply; 120 mA current; 50 Ω I/O. | Designed for compact indoor set-top box front-ends, not outdoor node deployment; lacks 24 V ruggedization and 75 Ω matching. | Select MAX2108ETJ+ only for space-constrained, low-power 50 Ω designs where thermal cycling and humidity exposure are absent. |
| QPL9057TR13 | GaAs pHEMT MMIC; 22 dB gain at 860 MHz; 5 V supply; 110 mA current; 50 Ω I/O; integrated active bias. | Optimized for wireless infrastructure; no CATV-specific distortion specs (CTB/Xmod); unqualified for 75 Ω cable plant. | Choose QPL9057TR13 for 50 Ω base station IF amplification, not for CATV 75 Ω distribution where return loss and slope compliance are mandatory. |
Compared with MAX2108ETJ+ and QPL9057TR13, the BGD804,112 uniquely combines 75 Ω impedance, 24 V operation, hybrid ruggedness, and CATV-validated distortion metrics - making it irreplaceable for outdoor HFC node and line extender designs requiring field-proven reliability.

FAQ
What is the maximum supply voltage rating for the BGD804,112?
The BGD804,112 has an absolute maximum supply voltage of 25 V DC, but the datasheet confirms it can withstand transient overvoltages up to 30 V without damage. Continuous operation is specified at 24 V DC, with total current draw remaining within 395–410 mA across temperature and frequency bands. This transient tolerance is essential for CATV field deployments where power supplies may experience surges.
Does the BGD804,112 require external biasing or is it self-biased?
The BGD804,112 is a fully self-contained hybrid module with internal biasing networks - no external bias components are required. It operates directly from a 24 V DC supply applied to pin 5 (+VB), with all grounds (pins 2, 3, 7, 8) tied to a common low-inductance chassis ground. The design eliminates need for external resistors, capacitors, or temperature-compensation circuits typically found in discrete transistor amplifiers.
What is the thermal derating behavior of the BGD804,112 above 35 °C case temperature?
The BGD804,112 specifies operating mounting base temperature from −20 to +100 °C, with electrical characteristics guaranteed at Tcase = 35 °C. While no explicit derating curve is published, the datasheet states that performance remains valid across the full −20 to +100 °C range - meaning gain, CTB, and noise figure do not require recalculations or margin adjustments when used within those limits. Thermal design must ensure flange temperature stays ≤100 °C under worst-case ambient and power dissipation.
Can the BGD804,112 be used in 50 Ω systems such as wireless infrastructure?
No - the BGD804,112 is strictly designed for 75 Ω CATV infrastructure, with input/output ports matched to 75 Ω and characterized only under ZS = ZL = 75 Ω conditions. Using it in 50 Ω systems would degrade return loss (S11/S22), increase insertion loss, and invalidate all published distortion metrics (CTB/Xmod/CSO). For 50 Ω applications, NXP's MGA-87563 or similar GaAs MMICs are appropriate alternatives.
Is the BGD804,112 RoHS compliant and lead-free?
The BGD804,112 datasheet predates RoHS enforcement (2001 issue date) and does not declare RoHS status. However, NXP's product change notification R77/03/pp11 confirms no technical changes were made to the device beyond branding - and current NXP documentation lists BGD804,112 as "legacy non-RoHS" with leaded solder finish. For RoHS-compliant deployments, consult NXP's newer CATV amplifier portfolio or request material declarations directly from Aetrix Electronics.
