Product details
Overview
MHW7182CN from Freescale Semiconductor is a 750 MHz CATV forward amplifier module using silicon bipolar transistor technology, delivering 19 dB typical power gain across 40–750 MHz, with ≤0.6 dB gain flatness and –70 dBc CSO (110-channel flat), designed for input-stage amplification in optical nodes and trunk distribution amplifiers.
For engineers reviewing the MHW7182CN datasheet, MHW7182CN pinout, MHW7182CN application, or MHW7182CN equivalent, key selection criteria include RF bandwidth (40–750 MHz), distortion performance (CSO/CTB/XMD < –63 dBc), gain slope (≤1 dB), noise figure (≤6.5 dB at 750 MHz), and 24 Vdc/220 mA DC operating point in a 9-pin surface-mount package.
Technical Context
This CATV amplifier operates in a 75 Ω system with unconditional stability under all load conditions, supporting both 77- and 110-channel flat signal loading. Its bipolar transistor architecture enables high linearity and low noise figure while maintaining thermal robustness over –20 to +100°C case temperature.
The device features fixed DC biasing (24 Vdc, ~220 mA), no external tuning components required, and delivers consistent RF performance without gain peaking or oscillation risk-critical for cascaded CATV trunk amplifiers where intermodulation distortion accumulates across stages.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar CATV amplifier module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MHW7182C | Direct predecessor; identical form, fit, and function per Freescale documentation; RoHS non-compliant. | No functional difference; legacy version lacks RoHS compliance and updated qualification testing. | Select MHW7182CN for new designs requiring RoHS compliance and current manufacturing traceability. |
| MAX2109 | SiGe-based, 5 Vdc operation, 45–1000 MHz bandwidth, higher gain (22 dB), but higher NF (6.5 dB @ 750 MHz) and lower CSO (–65 dBc). | Better suited for wideband or low-voltage systems; less optimal for legacy 24 Vdc CATV trunk infrastructure. | Choose MAX2109 only when migrating to SiGe platform or requiring extended upper frequency beyond 750 MHz. |
Compared with MHW7182C and MAX2109, the MHW7182CN offers best-in-class CSO/CTB at 24 Vdc within the 40–750 MHz CATV band, with guaranteed unconditional stability and RoHS compliance-making it the preferred choice for replacement and new-build optical node and trunk amplifier designs.

FAQ
What is the operating voltage range for the MHW7182CN?
The MHW7182CN is specified for 24 Vdc operation with absolute maximum DC supply voltage of +28 Vdc. It draws 180–240 mA at 24 Vdc and +30°C case temperature. Operation outside the 24 Vdc nominal range may degrade linearity or cause instability; the MHW7182CN does not support adjustable bias or dual-supply configurations.
Does the MHW7182CN require external matching components?
No, the MHW7182CN integrates internal broadband 75 Ω input and output matching networks. The device is designed for direct connection to 75 Ω coaxial traces or connectors without external capacitors, inductors, or resistors-verified across 40–750 MHz per Freescale's electrical characteristics table.
Is the MHW7182CN pin-compatible with earlier Freescale CATV modules?
Yes-the MHW7182CN replaces MHW7182C with no form, fit, or function changes, including identical pinout (Case 1302-01, Style 1), mechanical footprint, and electrical behavior. No PCB redesign or layout modification is required when upgrading from MHW7182C to MHW7182CN.
What is the thermal derating behavior of the MHW7182CN above +30°C case temperature?
The MHW7182CN datasheet specifies electrical characteristics at TC = +30°C. While maximum operating case temperature is +100°C, gain decreases ~0.015 dB/°C and distortion degrades gradually above +30°C. Derating curves are not published; thermal design must maintain case temperature ≤+85°C for sustained CSO < –68 dBc performance.
Can the MHW7182CN be used in reverse-path (upstream) CATV applications?
No-the MHW7182CN is optimized exclusively for forward-path (54–750 MHz) amplification. Its input/output matching, stability margins, and distortion specifications are validated only for downstream operation. Upstream use (5–42 MHz) is unsupported and may result in instability or degraded noise figure due to mismatched impedance and gain profile.
