MHW1254L

Overview

The MHW1254L is a narrow band high power amplifier module designed for broadband applications requiring low distortion characteristics. It operates within a frequency range of 5 MHz to 50 MHz and utilizes hybrid technology. The device features a 75 Ω characteristic impedance and provides a guaranteed broadband power gain of 24.3 dB. It is powered by a 24 V supply and can handle a maximum continuous wave input power of 21.25 dBm. The unit is housed in a CASE 1302-01 package with 9 pins, constructed from plastic/epoxy material equivalent to SOT-115J. It supports an operating temperature range from -20 °C to 100 °C.

Feature Summary

• Designed specifically for broadband applications requiring low distortion characteristics
• Features all gold metallization system
• Specified for use as return amplifiers for low-split, 2-way cable TV systems

Applications

• Return amplifiers for low-split cable TV systems
• Broadband applications requiring low distortion characteristics

Procurement Notes

Verify the specific datasheet revision and ordering suffix (e.g., /D) to ensure compatibility with current manufacturing standards. Confirm that the 75 Ω impedance requirement matches your system design. Check for any RoHS compliance updates or environmental declarations associated with the NXP Semiconductors product line, as Freescale branding has been retired. Ensure thermal management solutions accommodate the specified operating temperature range.

Selection Notes

Select this component when a narrow band high power amplifier is needed for cable TV return paths. The 75 Ω impedance is critical for matching coaxial cable infrastructure. Consider the 24 V power supply requirement and the hybrid construction method during system integration. Verify that the 5 MHz to 50 MHz bandwidth aligns with the required signal spectrum for the intended application.

Part Context

This part belongs to the RF and microwave category under wireless communications. Originally manufactured by Freescale Semiconductor, which merged into NXP Semiconductors, it serves as a specialized module for signal amplification. The device is distinct from general-purpose amplifiers due to its specific focus on low distortion and broadband performance in the 75 Ω domain.

Replacement Considerations

Consult official NXP documentation for direct cross-reference part numbers. Verify pinout compatibility and electrical specifications before substituting with other hybrid amplifier modules.
