Product details
Overview
BGE885,112 from NXP Semiconductors is a hybrid push-pull RF amplifier module designed for CATV distribution systems, operating from 40 MHz to 860 MHz with 17 dB small-signal power gain, 24 V DC supply, and 75 Ω input/output impedance. It delivers 59 dBmV output voltage under two-tone test conditions and maintains ±0.5 dB frequency response flatness across its bandwidth.
For engineers reviewing the BGE885,112 datasheet, BGE885,112 pinout, BGE885,112 application, or BGE885,112 equivalent, key selection criteria include its 860 MHz upper frequency limit, rugged SOT115D flanged package, low 7.5 dB noise figure at 350 MHz, and suitability for headend and node amplifier stages in broadband cable infrastructure.
Technical Context
The BGE885,112 implements a hybrid push-pull architecture using discrete GaAs FETs and passive matching networks to achieve high linearity and low distortion (–53 dB second-order) in 75 Ω CATV systems. Its design targets constant-gain operation over 40–860 MHz with minimal slope (0.2–1.2 dB cable-equivalent variation).
DC biasing is split across dedicated pins: Pin 4 supplies +12 V/60 mA for internal circuitry, while Pin 8 provides +VB (24 V), and Pins 1 and 9 carry DC-coupled RF signal paths with common ground return via Pins 2, 3, 5, 6, and 7 - enabling stable operation without external DC blocking on input/output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 40–860 MHz - fully specified performance across full CATV spectrum including DOCSIS 3.0/3.1 upstream/downstream bands |
| Power Gain | 16.5–17.5 dB at 50 MHz - ensures consistent signal boost with margin for cascaded amplifier stages |
| Noise Figure | 7.5 dB @ 350 MHz, 8 dB @ 860 MHz - preserves CNR in multi-stage trunk amplifiers |
| Output Voltage | 59 dBmV under two-tone dimming (–60 dB) - meets SCTE-47 composite distortion requirements |
| Current Consumption | ≤240 mA @ 24 V - enables thermal management in dense amplifier housings |
| Return Loss | ≥14 dB (40–450 MHz), ≥10 dB (450–860 MHz) - minimizes reflections in 75 Ω coaxial plant |
| Flatness | ±0.5 dB over 40–860 MHz - eliminates need for external equalization in standard nodes |
Pinout & Package
SOT115D: Rectangular single-ended metal-flange package with 9 gold-plated in-line leads, aluminum base for thermal dissipation, and dual vertical/horizontal mounting holes (6-32 UNC) for mechanical stability in outdoor CATV enclosures.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input | DC-coupled input port; requires external 75 Ω termination and DC blocking if source is not biased |
| 2,3,5,6,7 | Common Ground | Multiple low-inductance ground returns for RF shielding and thermal conduction to flange |
| 4 | +12 V Supply | Dedicated 60 mA rail for internal bias network - decoupling capacitor required per datasheet |
| 8 | +VB (24 V) | Main DC supply input; withstands transients up to 30 V per specification |
| 9 | RF Output | DC-coupled output port; drives 75 Ω coaxial plant directly with 59 dBmV capability |
Key Features
| Feature | Design Value |
|---|---|
| Push-pull hybrid topology | Enables –53 dB second-order distortion at 59 dBmV output, meeting stringent SCTE linearity standards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2661ETA+ | Single-ended 5 V GaAs MMIC; 15 dB gain; 40–1000 MHz; 3.5 dB NF; 50 Ω I/O | Designed for 50 Ω wireless infrastructure; lacks 75 Ω matching and CATV linearity specs | Use only with external impedance transformation and re-evaluation of distortion performance in 75 Ω plant |
| QPL9057 | 5 V LNA; 19 dB gain; 50–6000 MHz; 50 Ω; integrated active bias; no flange package | Targets 5G FR1 and WiFi; no CATV qualification, no 24 V operation, no SOT115D thermal interface | Not suitable for field-deployed CATV nodes; limited to lab evaluation of narrowband segments |
Compared with MAX2661ETA+ and QPL9057, the BGE885,112 uniquely combines 75 Ω system compatibility, 24 V rugged supply, flanged thermal packaging, and verified –53 dB two-tone distortion - making it irreplaceable for production CATV amplifier modules requiring regulatory compliance and field longevity.

FAQ
What is the maximum operating temperature for the BGE885,112?
The BGE885,112 has a maximum operating mounting base temperature (Tmb) of +100 °C, validated per IEC 60134 limiting values. This rating allows deployment in sealed outdoor amplifier housings exposed to direct sunlight, provided thermal interface resistance to heatsink remains within design limits specified in the SOT115D outline drawing.
Does the BGE885,112 require external DC blocking capacitors on input and output?
Yes, the BGE885,112 has DC-coupled RF ports (Pins 1 and 9), so external 75 Ω DC blocking capacitors are required unless the connected source and load provide compatible DC bias. The datasheet test circuit (Fig.2) confirms this requirement using C1 and C4 as 1 nF ceramic capacitors in series with input and output paths.
Can the BGE885,112 be operated from a 12 V supply instead of 24 V?
No - the BGE885,112 is specified for 24 V operation (VB = 24 V), with absolute maximum rating of 28 V. Pin 4 supplies +12 V/60 mA internally, but main bias is delivered via Pin 8 (+VB). Operation below 24 V results in undefined gain, increased distortion, and potential instability per the "Recommended operating conditions" section of the datasheet.
What is the meaning of "slope cable equivalent" (SL) parameter for the BGE885,112?
The slope cable equivalent (SL) of 0.2–1.2 dB quantifies how much the BGE885,112's gain varies across 40–860 MHz relative to coaxial cable attenuation slope. A lower SL value indicates better compensation for natural cable loss tilt, reducing need for external equalizers in long-haul CATV trunk lines.
Is the BGE885,112 qualified for automotive applications?
No - the BGE885,112 is explicitly designated for CATV infrastructure and is not automotive-qualified. The datasheet states "Non-automotive qualified products" and excludes life-critical, safety-critical, or automotive use. Its thermal and reliability validation applies only to fixed broadband cable plant environments.
