Product details
Overview
MHW7222BN from Freescale Semiconductor is a 40–750 MHz CATV forward amplifier module using silicon bipolar transistor technology, delivering 22.7 dB typical power gain at 750 MHz, −67 dBc CSO (110-channel), and 3.7 dB noise figure at 50 MHz for use as an input-stage amplifier in optical nodes and trunk distribution amplifiers.
For engineers reviewing the MHW7222BN datasheet, MHW7222BN pinout, MHW7222BN application, or MHW7222BN equivalent, key selection criteria include gain flatness (0.4 dB peak-to-valley), unconditional stability across all load conditions, distortion performance under 77- and 110-channel loading, and compatibility with 24 Vdc supply and 75 Ω CATV systems.
Technical Context
The MHW7222BN operates as a broadband RF gain block optimized for cable television infrastructure, with specified performance across 40–750 MHz in a 75 Ω system. It uses silicon bipolar transistors and maintains unconditional stability without external compensation networks.
Its electrical behavior is characterized at VCC = 24 Vdc and TC = +30°C, with DC current draw of 220 mA typical and thermal operation validated from −20°C to +100°C case temperature. Distortion metrics (CSO, CTB, XMD) are measured at defined output levels (e.g., +40 dBmV/ch for 110-channel) and reference frequencies (e.g., Fm = 55.25 MHz).

Equivalent & Alternatives
The following parts are listed as comparable options for similar CATV amplifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MHW7222B | Direct predecessor; identical form, fit, and function per Rev. 6 documentation; no electrical or mechanical changes. | No functional difference; MHW7222BN replaces MHW7222B in production with RoHS compliance upgrade. | Select MHW7222BN for new designs requiring RoHS compliance; MHW7222B remains viable only for legacy repair or obsolescence-limited sourcing. |
| MAX2130ETJ+ | SiGe-based 50–1000 MHz amplifier IC; 21 dB gain, 4.2 dB NF, requires external biasing and matching; surface-mount QFN package. | Not a drop-in replacement; used in newer, smaller-footprint designs where integration and board space are prioritized over module-level ruggedness. | Choose MAX2130ETJ+ only when redesigning PCB layout and accepting higher design validation effort for improved integration density. |
Compared with MHW7222B, the MHW7222BN offers identical RF performance with RoHS compliance, while the MAX2130ETJ+ provides wider bandwidth and smaller footprint at the cost of external component dependency and non-drop-in implementation.

FAQ
What is the operating frequency range of the MHW7222BN?
The MHW7222BN operates from 40 MHz to 750 MHz, covering the full forward-path spectrum used in traditional and digital CATV systems. This range supports both 77-channel and 110-channel loading configurations, and all electrical specifications-including gain, distortion, and return loss-are validated across this band under standard test conditions (24 Vdc, +30°C case temperature, 75 Ω system).
Is the MHW7222BN RoHS compliant?
Yes, the MHW7222BN is RoHS compliant as confirmed in Revision 6 (May 2006) of its official technical data sheet. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), meeting EU Directive 2002/95/EC requirements for environmentally restricted substances.
What is the DC supply requirement for the MHW7222BN?
The MHW7222BN requires a +24 Vdc supply, with a maximum rating of +28 Vdc. Its typical DC current draw is 220 mA at +24 Vdc and +30°C case temperature, and it draws up to 240 mA under worst-case conditions. The device includes built-in protection against overvoltage and is designed for direct integration into standard CATV power-insertion architectures.
Does the MHW7222BN require external stabilization components?
No, the MHW7222BN is unconditionally stable under all load conditions, as explicitly stated in its Freescale technical documentation. This eliminates the need for external resistive or reactive stabilization networks-reducing bill-of-materials count, PCB area, and design validation effort compared to conditionally stable RF amplifiers.
How does the MHW7222BN differ from the MHW7222B?
The MHW7222BN replaces the MHW7222B with no form, fit, or function changes-only an upgrade to RoHS compliance. All electrical parameters, pinout, package dimensions, and thermal ratings remain identical. Freescale explicitly states there are "no changes" beyond environmental compliance, making the MHW7222BN a seamless drop-in replacement for new production runs requiring RoHS adherence.
