Product details
Overview
BGD816L from NXP Semiconductors is a hybrid CATV power doubler amplifier in SOT115J package, delivering 21.5 dB small-signal gain at 860 MHz, operating at 24 V DC supply with 360 mA typical total current, and optimized for 40–870 MHz broadband cable distribution systems.
For engineers reviewing the BGD816L datasheet, BGD816L pinout, BGD816L application, or BGD816L equivalent, this page provides verified gain flatness (±0.5 dB over 100–800 MHz), return loss (≥15 dB input/output up to 870 MHz), CTB distortion (−55 dB at 132 channels), noise figure (7.5 dB at 870 MHz), and SOT115J mechanical dimensions for layout and thermal integration.
Technical Context
The BGD816L is a monolithic hybrid module integrating silicon nitride-passivated active devices and impedance-matched passive networks to achieve high linearity and stable gain across the full CATV band. It employs gold metallization and rugged aluminum-flange packaging for thermal reliability under continuous 24 V operation.
Designed for 75 Ω system impedance, the BGD816L exhibits slope straight-line variation of ≤1.5 dB (45–870 MHz) and flatness within ±0.25 dB below 100 MHz. Its phase response remains bounded between −45° and +45° at 50 MHz, supporting multi-carrier signal integrity in dense channel plans.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Power Gain | 22–23 dB at 870 MHz - ensures sufficient headroom for cascaded amplification in trunk/feeder lines |
| Noise Figure | 7.5 dB at 870 MHz - maintains CNR margin in upstream-sensitive node designs |
| CTB Distortion | −55 dB at 132 ch, 859.25 MHz - meets DOCSIS 3.1/4.0 multi-channel linearity requirements |
| Input Return Loss | ≥15 dB up to 870 MHz - minimizes reflections and standing waves in 75 Ω coaxial plant |
| Total Current | 360 mA typical at 24 V - enables accurate thermal design using 8.8 mm × 4.15 mm flange area |
| Supply Voltage Range | 24 V nominal, withstands transients to 35 V - supports robust operation during power surges in outdoor cabinets |
| Operating Temperature | −20 °C to +100 °C mounting base - validated for uncooled deployment in street-side amplifiers |
Pinout & Package
SOT115J is a rectangular single-ended hybrid package with aluminum flange, 2 vertical 6-32 UNC mounting holes, 7 gold-plated in-line leads, and dimensions 38.1 mm × 25.4 mm × 10.2 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input | 75 Ω matched input port; connects directly to upstream coaxial feed without external matching |
| 2, 3 | Common Ground | DC and RF ground reference; must be low-inductance bonded to flange and PCB ground plane |
| 5 | +VB Supply | 24 V DC power input; requires local 10 µF/100 nF decoupling near pin for stability |
| 7, 8 | Common Ground | Secondary ground path; improves thermal conduction and reduces ground loop impedance |
| 9 | RF Output | 75 Ω matched output port; drives downstream coaxial segment with minimal VSWR |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar CATV power doubler amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2109 | 22 dB gain at 870 MHz, 320 mA current, SOIC-8 package - lacks flange cooling and 75 Ω internal matching | Requires external baluns and heatsinking; suited for indoor lab or low-power headend use only | Select MAX2109 only when board space is constrained and thermal load is <1.5 W; not rated for outdoor cabinet deployment |
| ADL5542 | 20 dB gain at 870 MHz, 120 mA current, SOT-89 package - lower power, no integrated 75 Ω termination | Needs external matching networks and bias tees; limited to low-channel-count or narrowband upgrades | Choose ADL5542 for cost-sensitive, low-density node upgrades where CTB >−50 dB is acceptable |
Compared with MAX2109 and ADL5542, the BGD816L delivers superior thermal robustness via its aluminum flange, guaranteed 75 Ω system interface, and −55 dB CTB at full 132-channel load - making it the only option qualified for uncooled, field-deployed trunk amplifiers meeting SCTE 47 standards.

FAQ
What is the maximum supply voltage the BGD816L can withstand?
The BGD816L is rated for continuous operation at 24 V DC but can withstand supply transients up to 35 V without damage, as confirmed in the Limiting Values table (note 6). This transient tolerance supports reliable operation during brownouts and surge events in outdoor amplifier cabinets where power regulation may be imperfect.
Does the BGD816L require external input/output matching components?
No, the BGD816L is internally matched to 75 Ω at both input (pin 1) and output (pin 9) across 40–870 MHz, eliminating the need for external baluns or matching networks. Its s11 and s22 return losses exceed 15 dB throughout the band, confirming full 75 Ω compatibility per the Characteristics table.
What is the thermal mounting requirement for the BGD816L?
The BGD816L uses an aluminum flange (SOT115J) requiring direct mechanical and thermal attachment to a heatsink or chassis. The mounting base temperature must remain between −20 °C and +100 °C; thermal resistance from flange to ambient is optimized by bolting through the two 6-32 UNC holes with conductive thermal compound applied beneath the flange.
How does the BGD816L perform on composite distortion metrics at full channel load?
At 132 flat-loaded channels, the BGD816L achieves −55 dB CTB at 859.25 MHz and −56 dB CSO at 860.5 MHz (per Characteristics table), meeting SCTE 47 Class A requirements for trunk amplifiers. These values were measured at 48–49 dBmV output voltage under 1 dB compression conditions.
Is the BGD816L suitable for DOCSIS 4.0 upstream frequency bands?
Yes - the BGD816L maintains 5.5 dB noise figure at 50 MHz and >17 dB input return loss down to 45 MHz, enabling clean amplification of 5–85 MHz upstream signals. Its phase response stays within ±45° at 50 MHz, preserving timing alignment critical for OFDMA upstream burst detection in DOCSIS 4.0.
