MRF5P21240HR6 Обзор
RF power transistors such as the MRF5P21240HR6 sit within the LDMOS (Laterally Diffused Metal-Oxide Semiconductor) family - a subclass of power MOSFETs designed to combine high RF gain and ruggedness with reasonable cost. Within the broader taxonomy they are power transistors -> discrete semiconductors -> RF power devices. LDMOS has become the dominant technology for sub-3 GHz base-station PA stages because of its high breakdown voltage, excellent linearity gain in swept-back-off RF conditions, and ability to handle high peak-to-average ratios typical of multicarrier W-CDMA signals.
Key features include a minimum drain-source breakdown of 65 V (giving ample headroom above the 28 V operating rail), 603 W absolute maximum power dissipation, a common-source dual-element configuration, and surface-mount ceramic packaging. The device's 13 dB gain at 2.11 GHz and its high-efficiency performance under 2-carrier W-CDMA drive conditions make it a workhorse final-stage transistor for UMTS Band I (uplink/downlink) power amplifiers.
Architecturally, the MRF5P21240HR6 is built on NXP's 7th-generation (Gen7) high-voltage LDMOS process, which places two dies inside a single ceramic NI-1230 housing to achieve the 52 W average output level. Internally matched on the input and partially matched on the output for the 2110-2170 MHz band, the device is biased at IDQ = 2200 mA with VDD = 28 V to deliver its rated linear output power.
Typical applications include W-CDMA/UMTS base-station PAs (Band I), 2-carrier multi-carrier amplifier bricks, and cellular repeaters. Designers choose this part when they need proven LDMOS ruggedness in surface-mount ceramic packaging for high-power macro-cell or micro-cell infrastructure.
A practical design tip: the HR6 suffix denotes a lower-thermal-resistance ceramic package compared to the older MRF5P21240R6. When migrating from R6 to HR6 the PCB land pattern is identical, so existing base-station layouts can be reused without rework. Always verify load-pull impedance at your specific bias and frequency before finalizing the output matching network.

UMTS Band I W-CDMA Macro-Cell Base-Station PA
The MRF5P21240HR6 is the reference final-stage LDMOS transistor for UMTS Band I (2110-2170 MHz) macro-cell base-station power amplifiers. Its 52 W 2-carrier W-CDMA average output rating and 13 dB gain at 28 V are sized exactly for the 40-60 W Pout envelope required per PA brick in a typical 3-sector macro site. Designers choose this part because its high linearity gain under swept-back-off RF and its 65 V breakdown headroom guarantee ACPR margins even at full multi-carrier drive.
Рекомендуется
Multi-Carrier Linear Power Amplifier
The MRF5P21240HR6 is well suited to multi-carrier linear PA bricks that combine W-CDMA, LTE, and TD-SCDMA carriers in the same physical amplifier. Its LDMOS device's high peak-to-average tolerance and the NI-1230 ceramic package's low thermal resistance let the transistor sustain high dissipation without junction-temperature drift degrading linearity. Designers bias in Class AB at IDQ = 2200 mA and add digital predistortion (DPD) for ACLR compliance in multi-carrier macro sites.
Рекомендуется
Cellular Repeater / WLL Infrastructure
The MRF5P21240HR6 is used in cellular repeater and WLL (Wireless Local Loop) infrastructure operating in the 2110-2170 MHz band, where a 52 W average LDMOS PA stage extends coverage from a donor antenna to remote indoor or rural subscribers. Its surface-mount ceramic NI-1230 housing simplifies the mechanical build into a sealed outdoor enclosure, and its 65 V breakdown provides safety margin under high VSWR loads that repeaters occasionally see on poorly terminated donor antennas.
Рекомендуется
PCN-PCS / Cellular Radio Final Stage
The MRF5P21240HR6 can be deployed in Class AB final stages of legacy PCN-PCS cellular radio transmitters in the 2110-2170 MHz band, where its 13 dB gain at 2.11 GHz and 28 V rail operation match conventional driver-stage chain architectures. The device's two-element common-source internal topology simplifies PCB-level combining when higher output is needed by paralleling multiple NI-1230 devices.
Рекомендуется
Defense / Tactical RF Power Amplifier
Ruggedized defense and electronic-warfare subsystems in the 2110-2170 MHz range can use the MRF5P21240HR6 as a final-stage amplifier where LDMOS's inherent VSWR tolerance and NXP's hermetic ceramic packaging provide the reliability needed for field deployments. The 65 V breakdown and 603 W absolute dissipation ceiling support high-duty-cycle waveforms that would otherwise require more expensive GaN devices.
Рекомендуется
RF Test & Measurement Power Source
Lab and production RF test equipment uses the MRF5P21240HR6 as a known-good W-CDMA power source for calibrating over-the-air (OTA) chambers, base-station test racks, and EMC immunity setups in the UMTS Band I spectrum. Its repeatable 52 W 2-carrier W-CDMA performance and NXP-published load-pull data make it a stable reference PA for ATE-based test stations that need consistent RF drive across many test cycles.

Заметки по проектированию
The NI-1230 ceramic package must be bolted to a copper or aluminum heat-spreader with the recommended torque (typically 1.0-1.2 N-m for the M2.5 mounting screws) to ensure the lowest possible junction-to-case thermal resistance. Estimated: at 52 W RF output and 28 V supply, the device dissipates roughly 30-40 W as DC heat; without proper mounting torque the junction temperature can rise 30-40 C above the heatsink, risking premature failure. Use thermal interface material rated for high-power RF ceramics.
The MRF5P21240HR6 is a ceramic-packaged surface-mount device, but its RF input/output leads must be soldered to a high-frequency PCB substrate (Rogers RO4350B or equivalent) with controlled-impedance 50 ohm traces matched to the device's internal partial matching. Keep gate and drain traces short and avoid 90-degree bends; use mitered 45-degree bends. Place the bias feed network (RF choke + bypass capacitors) close to the gate lead to prevent low-frequency oscillation.
Do not operate the MRF5P21240HR6 above the 65 V breakdown rating - even brief over-voltage transients from a poorly regulated 28 V supply can permanently damage the LDMOS die. Estimated: the absolute maximum VDS is 65 V per the datasheet header, but the operating ceiling is typically limited to 32 V. Always add over-voltage protection on the drain bias rail and verify the supply's inrush behavior at power-on before applying RF drive.
The internal common-source dual-die configuration means each drain lead and each gate lead must be treated as a separate RF port - use a balanced microstrip layout with identical-length gate traces and identical-length drain traces to each internal die, or the two halves will not combine in phase and output power drops by 3 dB or more. Symmetry of the input/output matching networks is more important than absolute trace length in this part.
