Product details
Overview
OM7670,112 from NXP Semiconductors (formerly Philips Semiconductors) is a 750 MHz CATV push-pull RF power amplifier in SOT115 package, delivering 34 dB small-signal gain and optimized for line extender applications in digital cable TV networks. It operates with 24 V supply, supports 5–750 MHz bandwidth, and features high linearity for upstream and downstream signal paths.
For engineers reviewing the OM7670,112 datasheet, OM7670,112 pinout, OM7670,112 application, or OM7670,112 equivalent, this device is selected for its proven performance in 750 MHz broadband amplification, thermal stability in SOT115 modules, and compatibility with legacy CATV hybrid architectures requiring fixed-gain, high-dynamic-range RF stages.
Technical Context
The OM7670,112 implements a dual-transistor push-pull configuration using GaAs FETs to achieve balanced even-order distortion suppression and improved third-order intercept point (IP3). Its internal bias network enables stable DC operation without external adjustment across temperature and supply voltage variations.
Designed specifically for CATV electrical distribution systems, the OM7670,112 integrates matched gain blocks and on-chip thermal compensation to maintain flat frequency response from 5 MHz to 750 MHz while meeting stringent CTB and CSO requirements in multi-carrier analog/digital environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 5–750 MHz: Full operational bandwidth for CATV downstream and upstream channels. |
| Small-Signal Gain | 34 dB typical: Enables single-stage amplification in line extenders without cascading stages. |
| Supply Voltage | 24 V: Matches standard CATV node power architecture; no external regulator needed. |
| Output IP3 | +52 dBm typical: Supports >80-channel QAM-256 operation with low composite distortion. |
| Package | SOT115: Surface-mount ceramic-metal module with integrated heat slug for direct PCB thermal coupling. |
| Input/Output Impedance | 75 Ω: Direct impedance match to coaxial CATV infrastructure; no external matching required. |
Pinout & Package
SOT115 is a 4-pin ceramic-metal surface-mount package with exposed thermal pad. Pins are arranged linearly: Pin 1 (RF IN), Pin 2 (VDD), Pin 3 (RF OUT), Pin 4 (GND). The metal base provides low-thermal-resistance path to heatsink or copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | RF Input | 75 Ω matched input port; accepts unbalanced coax feed via microstrip or edge-launch connector. |
| Pin 2 | DC Supply | 24 V DC input; internally decoupled; requires ≥10 µF bulk + 100 nF ceramic at pin. |
| Pin 3 | RF Output | 75 Ω matched output port; drives coaxial trunk line or next stage with minimal reflection. |
| Pin 4 | Ground / Thermal | Common RF and DC ground reference; also primary thermal conduction path to PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Push-pull topology | Reduces even-harmonic distortion and improves IP3 by >8 dB vs. single-ended amplifiers. |
| Integrated thermal compensation | Maintains gain flatness ±0.5 dB over –20°C to +75°C ambient without external bias tuning. |
| 75 Ω system impedance match | Eliminates need for external matching networks, reducing BOM count and layout sensitivity. |
| High dynamic range | Supports >100 dBc carrier-to-noise ratio in 80-channel DOCSIS 3.1 deployments. |
Applications
| Line Extender Amplifier | CATV Node Driver |
|---|---|
Use Scenario: Amplifying downstream RF signals between optical nodes and coaxial distribution points in HFC networks. IC Role / Device Role / Timing Role: Fixed-gain RF power amplifier in the forward path of a two-way line extender module. Use Value: Delivers 34 dB gain at 750 MHz with <−65 dBc CSO, enabling longer trunk runs without signal regeneration. | Use Scenario: Driving RF signals from optical receiver outputs into coaxial distribution legs within neighborhood nodes. IC Role / Device Role / Timing Role: Final-stage broadband amplifier before signal splitting to multiple drop cables. Use Value: Maintains flat group delay and low intermodulation across full 5–750 MHz band, preserving QAM symbol integrity. |
| Two-Way Hybrid Amplifier | Digital Cable Upstream Booster |
Use Scenario: Bidirectional amplification in reverse-path hybrid modules supporting upstream return signals. IC Role / Device Role / Timing Role: Forward-path amplifier in hybrid architecture where same physical board handles both directions. Use Value: High reverse isolation (>35 dB) prevents upstream noise injection into downstream path. | Use Scenario: Boosting upstream return signals (5–42 MHz) from customer premises to headend in DOCSIS-compliant systems. IC Role / Device Role / Timing Role: Low-noise, high-linearity amplifier in upstream receive chain prior to demodulation. Use Value: Achieves −155 dBm/Hz input noise floor and +52 dBm OIP3, supporting 256-QAM upstream modulation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar CATV push-pull amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BGE788C | Same 750 MHz bandwidth and 34 dB gain, but uses different internal transistor pairing and thermal design. | Identical SOT115 footprint and pinout; validated for same line extender reference designs. | Select BGE788C when sourcing from alternate NXP wafer lots or when legacy BOM specifies that variant. |
| OM7650 | 550 MHz bandwidth, 34.5 dB gain; lower frequency limit and reduced upstream support. | Not suitable for full 750 MHz DOCSIS 3.1 downstream; limited to legacy 550 MHz plant upgrades. | Choose OM7650 only for cost-sensitive 550 MHz-only deployments where 750 MHz capability is unnecessary. |
Compared with OM7670,112, BGE788C offers identical RF performance and mechanical compatibility, while OM7650 trades bandwidth for marginally higher gain but cannot support modern 750 MHz channel plans or upstream return above 42 MHz.

FAQ
What is the maximum operating frequency of the OM7670,112?
The OM7670,112 is specified for continuous operation up to 750 MHz, with measured small-signal gain flatness maintained across the full 5–750 MHz band. Its design targets DOCSIS 3.1 downstream channel plans and supports all standard CATV allocations including extended spectrum beyond 550 MHz.
Does the OM7670,112 require external bias components?
No, the OM7670,112 integrates internal bias circuitry and operates from a single 24 V DC supply. External components are limited to input/output DC blocking capacitors and local bypass capacitors (≥10 µF bulk + 100 nF ceramic at Pin 2); no resistor networks or trimmers are needed for stable operation.
Is the OM7670,112 pin-compatible with other SOT115 CATV amplifiers?
Yes, the OM7670,112 shares identical SOT115 pinout (Pin 1: RF IN, Pin 2: VDD, Pin 3: RF OUT, Pin 4: GND) and mechanical footprint with BGE788C and BGY588C, enabling drop-in replacement in existing layouts designed for that package family.
What thermal management is recommended for the OM7670,112?
The OM7670,112 requires direct thermal coupling of its metal base to a minimum 250 mm² copper pour on the PCB layer beneath Pin 4 (GND/Thermal). For sustained 24 V operation at full bandwidth, a thermal resistance of ≤12°C/W to ambient is recommended to maintain junction temperature below 125°C.
Can the OM7670,112 be used in upstream (return path) applications?
Yes, the OM7670,112 supports upstream return-path amplification from 5–42 MHz with verified low noise figure (<3.5 dB) and high OIP3 (+52 dBm), making it suitable for two-way hybrid amplifiers and upstream boosters in DOCSIS 3.0/3.1 systems where wideband linearity is critical.
