MHL9236N Descripción general
An RF linear LDMOS amplifier is a power transistor amplifier designed to faithfully reproduce complex modulated waveforms (such as CDMA/WCDMA OFDM carriers) with minimal spectral regrowth and distortion. LDMOS (Laterally Diffused Metal-Oxide Semiconductor) is the dominant technology for cellular base-station power amplifiers because it combines high RF power density, high gain, and excellent ruggedness at relatively low cost. Within the RF power amplifier hierarchy, the MHL9236N sits between small-signal driver amplifiers and high-power (40 W+) macro-cell PAs, occupying the pico-cell / driver stage tier.
Key performance features include 30.5 dB typical power gain, 2.5 W linear output power in the 800–960 MHz cellular band, and a 26 V nominal drain supply. Internally matched for 50 ohm input and output, the part reduces external matching networks to a minimum and simplifies board integration. A silicon FET Class A bias topology provides very good linearity for digital modulation formats. The TO-272 WB-16 package offers excellent thermal performance for the 2.5 W power level while remaining compact enough for driver-stage layouts.
Typical applications include driver stages for cellular base-station power amplifiers, CDMA/TDMA repeaters, 900 MHz ISM-band linear power blocks, and general-purpose 800–960 MHz RF amplification where linearity is more critical than peak efficiency. The wide band also makes the MHL9236N attractive for driver duties in multi-standard BTS designs covering GSM/EDGE/UMTS front ends.
When designing with the MHL9236N, observe the 26 V supply rating and provide adequate heatsinking to keep the junction temperature below the datasheet-specified maximum. Input and output 50 ohm terminations must be preserved on the PCB to retain linearity - mismatch will degrade ACPR and EVM performance.

Aplicaciones típicas
MHL9236N es adecuado para 6 aplicacións: Cellular Base-Station Driver Stage, CDMA/TDMA Linear Power Amplifier, 900 MHz ISM Band Linear Amplifier, RF Repeater / Booster Driver, Multi-Standard BTS Front End, Test & Measurement Linear PA.
Cellular Base-Station Driver Stage
The MHL9236N's 30.5 dB gain and 2.5 W linear output make it an ideal driver for macro/pico-cell base-station PA cascades. Positioned between a small-signal gain block and the final high-power LDMOS stage, it provides the linear boost needed to maintain ACPR/EVM compliance for CDMA and TDMA carriers while its 50 ohm matching reduces inter-stage network complexity on the PCB.
Recomendado
CDMA/TDMA Linear Power Amplifier
Designed specifically for ultra-linear amplification of digitally modulated carriers, the MHL9236N delivers the spectral purity required for CDMA and cellular TDMA links. Its Class A silicon FET bias ensures minimal intermodulation distortion across the 800–960 MHz band, allowing cellular repeaters and remote radio heads to meet strict spectral mask requirements without external linearization.
Recomendado
900 MHz ISM Band Linear Amplifier
Within the 902–928 MHz ISM band, the MHL9236N provides 2.5 W of linear transmit power for industrial, scientific, and medical RF systems. Its wideband 800–960 MHz match covers the entire band without retuning, simplifying RF front-end design for RFID readers, wireless telemetry transmitters, and industrial sensor links where linearity outranks peak efficiency.
Recomendado
RF Repeater / Booster Driver
Cellular and public-safety RF repeaters rely on low-distortion driver stages to preserve signal integrity through cascaded amplification. The MHL9236N's 30.5 dB gain and ultra-linear Class A operation deliver the headroom and spectral purity required at the driver tier, while its 26 V supply and 50 ohm matching allow direct PCB integration into standard repeater modules.
Recomendado
Multi-Standard BTS Front End
The MHL9236N's 800–960 MHz bandwidth makes it equally useful in BTS front ends handling GSM, EDGE, UMTS, and early LTE deployments that share the cellular sub-band. The Class A bias gives designers a single driver part usable across modulation formats, reducing BOM complexity for multi-standard radio units serving legacy and modern cellular air interfaces simultaneously.
Recomendado
Test & Measurement Linear PA
Bench-top RF test sources and characterization equipment benefit from the MHL9236N's flat gain and ultra-linear Class A behavior. Designers building CW or modulated test amplifiers for the 800–960 MHz band can use the part as a known-good linear driver, taking advantage of its 50 ohm match and stable bias point to deliver repeatable test waveforms with low harmonic content.

Notas de diseño
Estimated: at 26 V drain and the 620 mA maximum supply current published in the datasheet, worst-case DC dissipation approaches 16 W with a fully-on bias point. In normal linear operation at 2.5 W Pout, RF dissipation typically lands around 6–8 W. The TO-272 WB-16 package requires at least 1 square inch of 2 oz copper (or a small bolted heatsink) to keep the junction within the datasheet-specified limit; without adequate heatsinking, output power will derate and the device may enter thermal shutdown.
Preserve the 50 ohm input and output transmission lines on the PCB to retain the datasheet performance - any extra matching components between the part and the connectors should be avoided. Use a continuous ground plane on layer 2 with abundant thermal vias stitching the TO-272 pad to ground; this both reduces lead inductance and improves thermal spreading.
Do not operate the MHL9236N below 24 V or above 28 V on the drain - undervoltage collapses linearity, while overvoltage risks SOA excursion. Ensure gate bias is sequenced on before drain, and off after drain, to avoid deep-pin-off breakdown. VSWR must remain below 1.5 in operation; higher mismatch can permanently damage the LDMOS die.
