Product details
Overview
MHW8222BN from Freescale Semiconductor is a CATV forward amplifier module based on silicon bipolar transistor technology, operating from 40 to 860 MHz with 22.7 dB typical power gain at 860 MHz, −68 dBc composite second order (CSO) at 128-channel loading, and 240 mA maximum DC current draw at +24 Vdc supply-designed for input-stage amplification in optical nodes and trunk distribution amplifiers.
For engineers reviewing the MHW8222BN datasheet, MHW8222BN pinout, MHW8222BN application, or MHW8222BN equivalent, key selection criteria include its 75 Ω system impedance compatibility, unconditional stability across all load conditions, specified distortion performance under 77-/110-/128-channel CATV loading, and RoHS-compliant Case 1302-01 package with defined RF input/output terminals and ground layout.
Technical Context
The MHW8222BN implements a broadband RF amplifier architecture optimized for CATV forward-path signal conditioning, featuring fixed-gain response with 0.8 dB typical slope (40–860 MHz) and 0.4 dB typical gain flatness (peak-to-valley). It operates exclusively in 75 Ω systems and requires +24 Vdc bias with no external matching components.
Its unconditional stability eliminates need for external stabilization networks, while silicon bipolar process ensures consistent distortion performance across temperature (−20°C to +100°C case) and channel-loading configurations-validated for CSO, CTB, and XMD at defined output levels per 77/110/128-channel test conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CATV amplifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MHW8222B | Direct predecessor; identical form, fit, and function per Freescale documentation-no electrical or mechanical changes. | No functional difference; legacy part superseded by MHW8222BN for RoHS compliance only. | Select MHW8222BN for new designs requiring RoHS-6 compliance; MHW8222B remains viable for legacy repair. |
| ERA-5SM+ | Wider bandwidth (DC–8 GHz), lower gain (18.5 dB), higher NF (3.5 dB), SMT package-not pin-compatible. | Used in lab/test equipment and broadband instrumentation, not CATV plant deployment. | Consider only for non-CATV R&D; lacks 75 Ω system optimization and channel-loading distortion specs. |
Compared with MHW8222B and ERA-5SM+, the MHW8222BN delivers CATV-specific distortion performance at 860 MHz with RoHS compliance and unconditional stability-making it uniquely suited for production cable infrastructure, whereas alternatives serve either legacy repair or non-CATV measurement roles.

FAQ
What is the supply voltage requirement for the MHW8222BN?
The MHW8222BN requires a +24 Vdc supply, with absolute maximum rating of +28 Vdc. Operation outside this range risks permanent damage. The device draws 180–240 mA depending on temperature and output level, and local decoupling (10 µF + 0.1 µF) is mandatory at Pin 5 (VDC) per Freescale layout guidance. The MHW8222BN does not support dual or negative supplies.
Does the MHW8222BN require external matching components?
No, the MHW8222BN features internally matched 75 Ω input and output ports. Its RF Input (Pin 1) and RF Output (Pin 9) are designed for direct connection to 75 Ω coaxial systems without external matching networks. This simplifies PCB layout and eliminates tuning dependencies-confirmed by Freescale's electrical characteristics table specifying return loss ≥20 dB at 40 MHz without external components.
Is the MHW8222BN pin-compatible with the MHW8222B?
Yes-the MHW8222BN replaces the MHW8222B with no form, fit, or function changes, as explicitly stated in the Freescale documentation. Both share identical Case 1302-01 packaging, pinout, electrical specifications, and thermal profile. The sole distinction is RoHS compliance in the MHW8222BN, making it a direct drop-in replacement for new designs.
What is the maximum operating case temperature for the MHW8222BN?
The MHW8222BN has a specified operating case temperature range of −20°C to +100°C. This rating applies to the metal case surface (not ambient air), and thermal design must ensure case temperature remains within this window under full-load conditions. Freescale specifies derating is not required within this range, and distortion performance (CSO/CTB/XMD) is validated at +30°C case temperature per test conditions.
Can the MHW8222BN be used in 50 Ω systems?
No-the MHW8222BN is characterized and optimized exclusively for 75 Ω CATV systems. Its input/output return loss, gain flatness, and distortion metrics are all specified in 75 Ω environments. Using it in 50 Ω systems results in degraded return loss (<15 dB), unpredictable gain response, and unverified distortion performance. Freescale does not publish 50 Ω data for the MHW8222BN.
