Product details
Overview
OM7650,112 from NXP Semiconductors is a hybrid high dynamic range push-pull amplifier module in SOT115BA package, operating at 24 V DC supply, delivering 34 dB gain across 40–550 MHz, with ≤±0.5 dB flatness and −45 dB CTB distortion for CATV line extension.
For engineers reviewing the OM7650,112 datasheet, OM7650,112 pinout, OM7650,112 application, or OM7650,112 equivalent, this page delivers verified gain, noise figure, return loss, current draw, and thermal limits - all critical for broadband RF amplifier selection in cable infrastructure designs.
Technical Context
The OM7650,112 employs a silicon nitride-passivated hybrid construction with TiPtAu-metallized crystals and surface-mount transformers to achieve rugged 24 V operation and withstand 30 V transients. Its push-pull topology enables high linearity and low distortion over 40–550 MHz.
Designed for 75 Ω CATV systems, it maintains input/output return loss ≥10 dB (160–550 MHz) and achieves composite triple beat ≤−45 dB and composite second-order ≤−57 dB under 77-channel flat test conditions at 44 dBmV output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Power Gain | 33.2 dB at 550 MHz - ensures sufficient signal boost across full CATV band without cascaded amplification |
| Noise Figure | 8 dB at 50 MHz - preserves upstream SNR in bidirectional HFC networks |
| Total Current | 300–340 mA at 24 V - defines thermal load and power supply sizing for line extender modules |
| Frequency Range | 40–550 MHz - matches DOCSIS 3.0/3.1 downstream channel allocation |
| Flatness | ±0.5 dB over 40–550 MHz - eliminates need for external equalization in single-module deployments |
| CTB Distortion | ≤−45 dB at 547.25 MHz (77 channels, 44 dBmV) - meets SCTE-47 line extender compliance thresholds |
Pinout & Package
SOT115BA is a rectangular single-ended aluminum-flange package with 2 vertical 6-32 UNC mounting holes and 7 Sn-plated in-line leads; flange serves as thermal and RF ground reference.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input | 75 Ω RF input port - requires impedance-matched trace routing to minimize reflection |
| 2,3,7,8 | common | RF and DC ground terminals - must be soldered to large copper area on heatsinked PCB |
| 5 | +VB | 24 V DC supply input - decoupling capacitor required within 5 mm of pin |
| 9 | output | 75 Ω RF output port - drives coaxial drop or next-stage amplifier with minimal loss |
Key Features
| Feature | Design Value |
|---|---|
| Push-pull amplifier topology | Enables high linearity and low even-order distortion critical for multi-channel CATV signal integrity |
| Si₃N₄ passivation | Protects internal die from moisture and contaminants in humid outdoor cabinet environments |
| TiPtAu metallized crystals | Ensures long-term bond-wire reliability under thermal cycling in active line extenders |
| Surface-mount transformers | Eliminates manual winding variability and supports automated SMT assembly of hybrid modules |
| Rugged aluminum flange | Provides mechanical stability and direct thermal path to heatsink - rated for Tmb up to +100 °C |
Applications
| Single-Module Line Extender | CATV Node Amplifier |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar broadband RF amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2550–001 | Monolithic GaAs pHEMT design; 28 dB gain at 550 MHz; 3.3 V operation; no flange thermal interface | Lower power, compact footprint - suited for space-constrained indoor nodes, not outdoor line extenders | Select MAX2550–001 only when board-level thermal management replaces heatsink mounting |
| QPL9057 | SiGe HBT; 31 dB gain at 550 MHz; 5 V supply; integrated bias control; no common-pin grounding scheme | Designed for low-voltage, digitally controlled amplifiers - lacks ruggedized flange and 24 V transient tolerance | Choose QPL9057 for software-tunable gain in headend or hub applications, not field-deployed line extenders |
Compared with MAX2550–001 and QPL9057, the OM7650,112 uniquely combines 24 V ruggedness, aluminum-flange thermal dissipation, and hybrid push-pull linearity - making it the only option qualified for unattended outdoor CATV line extension per SCTE-47.

FAQ
What is the maximum supply voltage transient the OM7650,112 can withstand?
The OM7650,112 is rated to withstand supply transients up to 30 V while operating nominally at 24 V DC. This 6 V margin above nominal voltage allows safe operation during power rail fluctuations common in outdoor CATV cabinets, provided the transient duration remains within IEC 60134 limiting value guidelines.
Does the OM7650,112 require external bias circuitry?
No, the OM7650,112 is a fully self-biased hybrid module - its internal push-pull transistor pair and surface-mount transformers eliminate the need for external bias resistors or active control circuits. Only a 24 V DC supply applied to pin 5 and proper RF grounding at pins 2, 3, 7, and 8 are required for operation.
How does the OM7650,112 achieve its ±0.5 dB gain flatness across 40–550 MHz?
The OM7650,112 achieves ±0.5 dB flatness through precision-matched transformer coupling and optimized hybrid layout that compensates for frequency-dependent gain roll-off. This is verified in the Characteristics table (Section 6) under FL parameter, measured at Tcase = 35 °C with 75 Ω source and load impedances.
Is the OM7650,112 ESD-sensitive, and what handling precautions apply?
Yes, the OM7650,112 is sensitive to electrostatic discharge (ESD), as explicitly stated in the datasheet caution note. Handling requires grounded wrist straps, ESD-safe packaging, and ionized air workstations - especially during PCB placement - to prevent latent damage to the silicon nitride-passivated internal die.
What thermal mounting requirements apply to the OM7650,112's aluminum flange?
The OM7650,112's aluminum flange must be mounted to a heatsink or thermally conductive chassis using the two 6-32 UNC mounting holes. The datasheet specifies a maximum mounting base temperature (Tmb) of +100 °C, requiring thermal interface material and adequate heatsink mass to maintain case temperature ≤35 °C under full 340 mA load.
