Product details
Overview
MHW9188AN from Freescale Semiconductor is a GaAs-based CATV forward power doubler amplifier module designed for 47–870 MHz broadband distribution systems. It delivers 20.3 dB typical gain at 870 MHz, supports 132-channel loading with –62 dBc typical CSO, and operates from a +24 Vdc supply with 425 mA typical current draw - deployed in optical node output stages and trunk amplifiers.
For engineers reviewing the MHW9188AN datasheet, MHW9188AN pinout, MHW9188AN application, or MHW9188AN equivalent, key selection criteria include its 75 Ω impedance match, unconditional stability across all load conditions, built-in input diode protection, and RoHS-compliant Case 1302-01 Style 1 package with defined RF input/output terminals and ground layout.
Technical Context
The MHW9188AN implements a two-stage GaAs FET power doubler architecture optimized for linear CATV signal amplification in 75 Ω coaxial systems. Its design ensures flat gain response (≤0.5 dB peak-to-valley over 47–870 MHz) and maintains unconditional stability without external compensation networks under all VSWR conditions.
It targets high-output, low-distortion operation in multi-channel configurations: specified for 132-, 112-, and 79-channel flat or tilted spectra, with distortion performance validated at +48 dBmV/channel (132-ch) and +56/+58 dBmV/channel (79-/112-ch equivalents), and noise figure held to ≤5.0 dB across 50–870 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 47–870 MHz - Full-band support for North American and global CATV spectrum allocation including analog video, digital QAM, and DOCSIS channels. |
| Power Gain (870 MHz) | 20.3 dB typical - Enables single-stage amplification to meet +48 dBmV/channel output requirements in 132-channel systems. |
| Gain Flatness | ≤0.5 dB peak-to-valley (47–870 MHz) - Minimizes channel-to-channel level variation without need for external equalization. |
| Composite Second Order (CSO) | –62 dBc typical (132-ch flat, +48 dBmV/ch) - Meets stringent cable system linearity mandates for analog/digital coexistence. |
| Noise Figure | ≤5.0 dB (50–870 MHz) - Preserves upstream SNR margin in cascade applications where multiple amplifiers are deployed. |
| DC Supply & Current | +24 Vdc / 425 mA typical - Compatible with standard CATV power insertion infrastructure; thermal design accommodates +100°C case temperature. |
| Input/Output Impedance | 75 Ω - Direct interface with coaxial distribution networks without matching transformers or baluns. |
Pinout & Package
Package: Case 1302-01, Style 1 - Hermetically sealed metal-ceramic module with integrated heat slug, designed for surface-mount soldering and chassis grounding via pins 2, 3, 7, and 8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input | 75 Ω matched input port; accepts upstream signal from fiber receiver or preceding amplifier stage. |
| 2, 3, 7, 8 | Ground | Four dedicated ground terminals ensure low-inductance RF return path and thermal conduction to heatsink/chassis. |
| 5 | VDC | +24 Vdc supply input; decoupling capacitor must be placed adjacent to pin per layout guidelines. |

Key Features
| Feature | Design Value |
|---|---|

| Output Port Ring Wave Protection | Integrated circuitry suppresses reflected energy from open/shorted outputs, preventing device damage during installation or fault conditions. |
| GaAs FET Technology | Delivers higher gain and lower noise than Si-based alternatives while maintaining robustness in high-output CATV applications. |
Applications
| Optical Node Output Stage | Trunk Distribution Amplifier |
|---|---|
Use Scenario: Final amplification stage in fiber-to-coax optical nodes converting downstream RF signals for coaxial distribution. IC Role / Device Role / Timing Role: Forward power doubler amplifier providing broadband gain and distortion-limited output to feed 10–20 homes/passive splits. Use Value: Delivers +48 dBmV/channel into 132-channel flat spectrum with –62 dBc CSO, enabling compliance with SCTE-47 linearity standards. | Use Scenario: Mid-span amplification in aerial or underground trunk lines carrying signals between headend and neighborhood hubs. IC Role / Device Role / Timing Role: High-output, thermally robust CATV amplifier operating continuously at +100°C case temperature in unventilated enclosures.

IC Role / Device Role / Timing Role: General-purpose RF power doubler with 75 Ω I/O, usable in lab-grade signal generation or monitoring paths. Use Value: Noise figure ≤5.0 dB and gain flatness ≤0.5 dB enable accurate amplitude response calibration without post-compensation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar CATV amplifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MHW9188A | Direct predecessor; identical electrical specs, pinout, and package - superseded by MHW9188AN with no form, fit, or function changes. | No operational difference; legacy stock may lack RoHS compliance documentation. | Select MHW9188AN for new designs requiring RoHS-compliant sourcing and current manufacturing traceability. |
| ERA-5SM+ | DC–1 GHz GaAs MMIC amplifier; 50 Ω I/O, +18 dB gain, +30 dBm P1dB - not 75 Ω matched and lacks CATV-specific distortion optimization. | Suitable for lab/test use or 50 Ω systems only; cannot replace MHW9188AN in 75 Ω CATV infrastructure without impedance conversion. | Choose ERA-5SM+ only for non-CATV 50 Ω applications where broadband gain matters more than channelized distortion performance. |
Compared with MHW9188A, the MHW9188AN offers identical performance with documented RoHS compliance; compared with ERA-5SM+, it provides native 75 Ω interface, CATV-validated distortion specs, and unconditional stability in coaxial plant environments - making it irreplaceable for production CATV hardware.

FAQ
What is the recommended DC decoupling for the MHW9188AN?
Per Freescale's layout guidance, a 10 µF tantalum capacitor and 0.1 µF ceramic capacitor should be placed directly at Pin 5 (VDC) with minimal trace length. This dual-capacitor network suppresses low- and high-frequency supply noise, ensuring stable operation under dynamic channel loading and preventing oscillation in the MHW9188AN's GaAs FET stages.
Does the MHW9188AN require external bias adjustment?
No, the MHW9188AN is internally biased for +24 Vdc operation and requires no external bias network or trim adjustment. Its quiescent current is factory-set at 425 mA typical, and the module maintains stable Class AB operation across –20°C to +100°C case temperature without user intervention - simplifying design and reducing bill-of-materials count.
Can the MHW9188AN be used in 50 Ω systems?
The MHW9188AN is strictly a 75 Ω device: both input and output ports are impedance-matched to 75 Ω, and its distortion specifications assume 75 Ω terminations. Using it in a 50 Ω system without external matching will cause significant return loss degradation and unpredictable CSO/CTB performance - the MHW9188AN is not rated or characterized for 50 Ω applications.
What thermal management is required for continuous operation of the MHW9188AN?
The MHW9188AN must be mounted on a thermally conductive surface (e.g., aluminum chassis or heatsink) using all four ground pins (2, 3, 7, 8) for mechanical and thermal contact. Freescale specifies ≤+100°C case temperature; at 425 mA and +24 Vdc, thermal resistance from case to ambient must be ≤25°C/W to avoid derating - forced air cooling is not required if PCB copper area and mounting pressure meet datasheet recommendations.
Is the MHW9188AN pin-compatible with newer NXP CATV modules?
No, the MHW9188AN uses Case 1302-01 Style 1 packaging with nine-terminal layout, which is not pin-compatible with later NXP CATV modules such as the MHT1200 series. Those devices use different footprints, 50 Ω or configurable I/O, and digital bias control - direct replacement would require PCB redesign and requalification of linearity and thermal behavior for the MHW9188AN.
