Product details
Overview
MHW6342T from Freescale Semiconductor is a CATV forward amplifier module based on silicon bipolar transistor technology, operating from 40 to 550 MHz with 35.2 dB typical power gain at 550 MHz, 5.5 dB typical noise figure, and −63 dBc composite triple beat (77-channel flat loading). It delivers stable DC current (310 mA typ) and unconditionally stable RF performance in cable TV distribution line amplifiers.
For engineers reviewing the MHW6342T datasheet, MHW6342T pinout, MHW6342T application, or MHW6342T equivalent, key selection criteria include its 77-channel distortion performance (XMD77/CTB77/CSO77), gain flatness (0.3 dB typ), input/output return loss (≥16 dB across 40–550 MHz), and case temperature range (−20°C to +100°C) for outdoor plant deployment.
Technical Context
The MHW6342T implements a single-stage broadband CATV amplifier architecture optimized for 75 Ω systems, using silicon bipolar transistors to achieve high linearity and thermal stability without external bias compensation. Its unconditional stability across all load conditions eliminates need for external stabilization networks.
Designed for fixed 24 Vdc operation, it maintains consistent gain slope (0–2 dB), return loss, and distortion metrics over temperature and channel loading-enabling drop-in use in legacy 77-channel CATV trunk and distribution amplifiers without recalibration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CATV amplifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MHW6342TN | RoHS-compliant version; identical electrical specs, same package and pinout; N suffix denotes lead-free finish. | No functional difference; intended for new designs requiring RoHS compliance. | Select MHW6342TN for new production; MHW6342T remains valid for legacy repair or non-RoHS environments. |
| MAX2541 | Lower gain (28 dB), higher NF (7.5 dB), narrower bandwidth (45–870 MHz), GaAs pHEMT process. | Targeted at DOCSIS 3.1 upstream + downstream dual-band systems, not 77-channel flat CATV. | Use MAX2541 only when extended upper-band coverage or lower power consumption (180 mA) is prioritized over CATV distortion specs. |
Compared with MHW6342TN and MAX2541, the MHW6342T offers superior 77-channel distortion performance and thermal stability for legacy CATV plant upgrades, while MHW6342TN provides identical functionality with RoHS compliance, and MAX2541 serves different architecture needs with trade-offs in gain and noise.

FAQ
What is the primary function of the MHW6342T in a CATV system?
The MHW6342T functions as a forward-path broadband RF power amplifier module in cable TV distribution networks. It provides 35.2 dB typical gain across 40–550 MHz, enabling signal boosting between headend and subscriber nodes. Its design ensures compliance with 77-channel flat loading requirements, making the MHW6342T suitable for trunk and distribution line amplifiers where distortion and thermal stability are critical.
Does the MHW6342T require external biasing or stabilization components?
No, the MHW6342T does not require external biasing or stabilization components. It integrates internal bias circuitry for 24 Vdc operation and is unconditionally stable under all load conditions up to 2:1 VSWR. This eliminates the need for external isolators, resistive terminations, or gain-tilt networks-reducing bill-of-materials count and board space in amplifier designs using the MHW6342T.
What is the meaning of "Replaced by MHW6342TN" in the MHW6342T documentation?
"Replaced by MHW6342TN" indicates that MHW6342TN is the RoHS-compliant successor to MHW6342T, with identical electrical, mechanical, and functional specifications. The "N" suffix denotes lead-free finish; there are no form, fit, or function changes. The MHW6342T remains orderable for legacy repair, but new designs should specify MHW6342TN to meet environmental compliance requirements without altering the MHW6342T's performance or integration.
What are the maximum RF input and DC supply ratings for the MHW6342T?
The MHW6342T has a maximum RF input voltage rating of +55 dBmV (single tone) and a maximum DC supply voltage of +28 Vdc. Its recommended operating condition is 24 Vdc, drawing 310–340 mA depending on temperature. Exceeding +28 Vdc risks permanent damage, and RF input above +55 dBmV may cause compression or reliability degradation-both limits are specified in the official MHW6342T datasheet Rev. 6.
How does the MHW6342T perform under temperature variation in outdoor installations?
The MHW6342T is characterized for operation from −20°C to +100°C case temperature, with stable DC current (310–340 mA) and consistent gain flatness (0.3 dB typ) across this range. Its silicon bipolar architecture and thermal design ensure minimal gain drift and distortion shift in sealed pole-mounted enclosures-making the MHW6342T suitable for uncooled outdoor plant use without derating or external thermal management.
