Product details
Overview
MHW9236N from Freescale Semiconductor is a GaAs-based CATV forward amplifier module designed for 40–870 MHz RF signal distribution in cable television infrastructure. It delivers 23.8 dB typical gain at 870 MHz, supports 132-channel loading, and operates from a +24 Vdc supply with 255 mA typical current draw. Its role is as an input-stage amplifier in optical nodes and trunk distribution amplifiers.
For engineers reviewing the MHW9236N datasheet, MHW9236N pinout, MHW9236N application, or MHW9236N equivalent, key selection criteria include its 0.55 dB typical gain slope (40–870 MHz), −64 dBc typical CSO at 132-channel flat output, 18–20 dB input/output return loss across band, and unconditional stability under all load conditions.
Technical Context
The MHW9236N is a monolithic GaAs FET amplifier module optimized for broadband CATV forward-path applications. It integrates ESD protection diodes per IEC 1000-4-5 (200 V surge) and MIL-STD-1686 (2 kV HBM), and maintains unconditional stability without external compensation networks across 40–870 MHz.
Its electrical performance is specified at +24 Vdc, +30°C case temperature, and 75 Ω system impedance. Distortion metrics (CSO, CTB, XMD) are measured at defined output levels per channel count (79/112/132), with noise figure ranging from 5.0 dB at 50 MHz to 5.3 dB at 870 MHz.

The following parts are listed as comparable options for similar CATV forward amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MHW9236 | Direct predecessor; identical form, fit, and function per Freescale documentation; RoHS-compliant revision replaces legacy version. | No functional difference; MHW9236N supersedes MHW9236 with same pinout and electrical specs. | Select MHW9236N for new designs requiring RoHS compliance and current production availability. |
| ERA-5SM+ | 50 Ω system, 0.05–8 GHz bandwidth, +15.5 dB gain, +20 dBm P1dB - not 75 Ω or CATV-optimized. | Designed for lab/test systems, not HFC plant deployment; lacks 132-channel distortion specs and ESD rating. | Use only for bench evaluation or non-CATV 50 Ω applications; not a functional replacement. |
Compared with MHW9236 and ERA-5SM+, the MHW9236N uniquely combines 75 Ω impedance, 132-channel distortion validation, unconditional stability, and integrated ESD - making it the sole qualified choice for production CATV forward-path amplification.

FAQ
What is the operating frequency range of the MHW9236N?
The MHW9236N operates from 40 MHz to 870 MHz, covering the full forward-path spectrum used in modern CATV systems including analog video, digital QAM, and DOCSIS downstream channels. This bandwidth is validated per Freescale's Rev. 6 datasheet with gain, flatness, and distortion performance fully characterized across the range.
Does the MHW9236N require external biasing components?
No, the MHW9236N integrates internal bias circuitry for its GaAs FETs and operates directly from a +24 Vdc supply applied to Pin 5. No external resistors, capacitors, or regulators are needed for basic operation - simplifying design and improving reliability in field-deployed amplifiers.
Is the MHW9236N RoHS compliant?
Yes, the MHW9236N is RoHS compliant per Freescale documentation (Rev. 6, 4/2006). It replaced the non-RoHS MHW9236 with no form, fit, or function changes - enabling seamless transition in environmentally regulated production environments without layout or performance impact.
What is the thermal performance limit for continuous operation of the MHW9236N?
The MHW9236N supports continuous operation at case temperatures from −20°C to +100°C. Its metal-ceramic Case 1302-01 package provides efficient thermal conduction to heatsinks or chassis mounting surfaces, and its GaAs FET design minimizes thermal drift in gain and distortion over this full range.
How does the MHW9236N handle ESD events in real-world CATV installations?
The MHW9236N incorporates integrated ESD protection diodes rated to 2 kV per Human Body Model (MIL-STD-1686) and 200 V per IEC 1000-4-5 surge standard on both RF input and output pins. This allows safe handling during installation and resilience against induced transients in outdoor plant environments.
