Product details
Overview
MHW8272AN from Freescale Semiconductor is a 40–870 MHz CATV forward amplifier module using silicon bipolar transistor technology, delivering 27.7 dB typical power gain at 870 MHz, 0.4 dB typical gain flatness (40–870 MHz), and −69 dBc typical CSO/CTB distortion under 128-channel flat loading at +38 dBmV/ch output - deployed as input-stage amplifiers in optical nodes and trunk distribution amplifiers for broadband cable infrastructure.
For engineers reviewing the MHW8272AN datasheet, MHW8272AN pinout, MHW8272AN application, or MHW8272AN equivalent, key selection criteria include RF bandwidth coverage (40–870 MHz), distortion performance (CSO/CTB ≤ −64 dBc worst case), gain slope (≤2 dB over full band), unconditional stability, and compatibility with 75 Ω CATV system impedance and +24 Vdc supply.
Technical Context
The MHW8272AN operates as a single-stage broadband RF amplifier optimized for CATV forward-path applications, with fixed +24 Vdc bias and internally matched 75 Ω input/output impedance. Its silicon bipolar architecture ensures unconditionally stable operation across all load conditions and temperature extremes (−20°C to +100°C case).
It targets 128-channel flat spectral loading per SCTE standards, achieving specified distortion performance (CSO128, CTB128, XMD128) at +38 dBmV/ch output level while maintaining 6.0 dB noise figure at 50 MHz and 5.5 dB at 870 MHz - critical for cascaded node designs requiring low accumulated noise and high linearity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CATV amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2102 | SiGe process; 25.5 dB gain at 870 MHz; higher NF (7.5 dB); requires external bias sequencing. | Designed for hybrid fiber-coax headend systems with tighter thermal constraints. | Prefer MAX2102 only when lower DC current (<200 mA) and integration with digital control are required. |
| MW6IC2240 | LDMOS process; 30.5 dB gain; higher P1dB (+32 dBm); requires +28 Vdc supply and external matching. | Targeted at high-output trunk amplifiers needing >+45 dBmV/ch drive capability. | Select MW6IC2240 only when output power >+40 dBmV/ch and thermal headroom >5 W are mandatory. |
Compared with MAX2102 and MW6IC2240, the MHW8272AN offers optimal balance of gain flatness (0.4 dB), distortion (−69 dBc), and +24 Vdc simplicity for mid-tier optical node and line extender roles - avoiding SiGe complexity or LDMOS thermal overhead.

FAQ
What is the operating frequency range of the MHW8272AN?
The MHW8272AN operates from 40 MHz to 870 MHz, covering the full forward-path spectrum used in North American and international CATV systems. This range supports analog video, digital QAM, and DOCSIS signals without band-limiting filters. The device maintains specified gain, flatness, and distortion performance across the entire band under +24 Vdc bias and 75 Ω system impedance.
Is the MHW8272AN a direct replacement for the MHW8272A?
Yes, the MHW8272AN replaces the MHW8272A with no form, fit, or function changes - including identical pinout, electrical specifications, package dimensions (Case 1302-01, Style 1), and thermal characteristics. Freescale explicitly states this in the datasheet, confirming backward compatibility for field upgrades and inventory rationalization without PCB or firmware modifications.
What is the typical power consumption of the MHW8272AN?
The MHW8272AN draws 310 mA typical DC current at +24 Vdc supply voltage and +30°C case temperature, resulting in approximately 7.4 W of power dissipation. This value is confirmed in Table 2 of the datasheet and aligns with its role as a medium-power CATV amplifier module - requiring adequate heatsinking in enclosed outdoor housings but avoiding active cooling.
Does the MHW8272AN require external matching components?
No, the MHW8272AN features fully internal 75 Ω input and output matching, eliminating the need for external baluns, transformers, or discrete matching networks. Its RF ports are directly compatible with standard CATV coaxial interfaces and PCB traces designed for 75 Ω characteristic impedance, simplifying layout and reducing bill-of-materials count.
What distortion metrics are guaranteed for the MHW8272AN under 128-channel loading?
The MHW8272AN guarantees CSO128, CTB128, and XMD128 distortion performance at −64 dBc minimum (worst case) when operated at +38 dBmV/ch output level under flat 128-channel loading. Typical values are −69 dBc for CSO128 and CTB128, and −65 dBc for XMD128 - meeting SCTE-47 compliance thresholds for modern digital cable deployments.
