MRF8S9220HSR3 概要
An RF power LDMOS (Laterally Diffused Metal-Oxide Semiconductor) is a specialized power transistor technology optimized for high-frequency, high-power RF amplification. LDMOS transistors sit within the broader MOSFET family and the power management hierarchy of RF front-end components. Compared to bipolar junction transistors (BJTs), LDMOS provides higher gain, better efficiency, and superior thermal stability, making it the dominant technology in cellular base station power amplifiers from 700 MHz through 2.7 GHz. The MRF8S9220HSR3 is part of NXP's HV8 family of 50 V-rated lateral RF MOSFETs.
Key features include typical 19.4 dB power gain at 960 MHz, single-carrier W-CDMA operation at 28 V VDD, integrated ESD protection, and Ni-pad gold-free metallization for high-volume assembly. Characterized with series-equivalent large-signal impedance parameters, the device supports both Class AB and Class C bias configurations across common cellular modulation formats including CDMA2000, W-CDMA, and LTE.
Designers can use this part in Doherty, Class AB push-pull, or single-ended final-stage topologies. The 70 V maximum drain-source rating provides substantial avalanche headroom over the 28 V nominal operating voltage, supporting robust SWR mismatch tolerance. Series-equivalent output impedance data is published to streamline matching network synthesis on FR-4 or ceramic substrates.
Typical applications include 900 MHz GSM/EDGE base station PAs, LTE band 8 final-stage amplifiers, RFID reader transmitters, industrial RF heating, and ISM-band solid-state power sources. The wide frequency coverage also supports amateur radio amplifiers in the 902-928 MHz ISM segment.
When designing with this part, bias the gate at approximately 2.8 V quiescent for Class AB and ensure the thermal interface uses a clamped or soldered heatsink. Designers should also confirm adequate drain-side decoupling (10 uF + 1 nF) close to the package tab to suppress VDD ringing under W-CDMA envelope peaks.

900 MHz Cellular Base Station Power Amplifier Final Stage
The MRF8S9220HSR3 delivers 65 W average W-CDMA output at 920-960 MHz per the NXP datasheet MRF8S9220H, fitting macro-cell base station final stages that target LTE band 8, CDMA2000, and W-CDMA simultaneously. Its 19.4 dB typical gain eliminates a separate driver stage, simplifying the RF chain. Used in a single-ended Class AB PA with published series-equivalent output impedance, it provides 30-35% drain efficiency at full output. The 70 V VDS rating gives substantial mismatch tolerance for antenna VSWR events typical in field-deployed cellular sites.

LTE Band 8 (900 MHz) Macro-Cell PA
The MRF8S9220HSR3's 65 W average output and 920-960 MHz coverage make it a direct fit for LTE band 8 macro-cell base station final stages per the NXP datasheet MRF8S9220H. The 100% PAR-tested rating guarantees linear output under LTE envelope statistics (about 7-9 dB peak-to-average ratio). Placed between the DPD pre-distortion block and the duplexer, it provides the RF power envelope needed for 4x4 MIMO antenna arrays at the sector. Compared to smaller LDMOS, it eliminates driver stage thermal overhead and improves overall system efficiency.

設計ノート
Estimated: At 28 V VDD, 65 W average W-CDMA output, and ~30% drain efficiency, total DC input power is ~217 W and dissipation is ~152 W. The NI-780S ceramic package requires a clamped or screw-down heatsink with thermal compound; aim for a heatsink thermal resistance below 0.5 C/W to keep junction temperature under 150 C. Forced-air cooling is mandatory for continuous W-CDMA operation. Always derate to 70% of rated Pout if the heatsink temperature exceeds 85 C ambient.
Place drain-side decoupling capacitors (10 uF electrolytic + 1 nF + 100 pF ceramic) within 5 mm of the package drain lead to suppress VDD ringing under W-CDMA envelope peaks. The input matching network should use a 50 Ohm microstrip line on the substrate directly abutting the gate lead, with a series DC-blocking capacitor at the gate. Keep the source ground leads (the package flange bottom) directly soldered to the PCB ground plane with multiple via fences for lowest source inductance.
Do not exceed 70 V VDS even transiently - antenna mismatch events can cause voltage doubling at the drain. Add a TVS clamp rated for 60 V working voltage between drain and ground. Gate bias should be applied before drain voltage (sequencing), and the gate voltage must be removed before drain voltage to prevent hot-switching damage. Confirm ESD precautions when handling the NI-780S package, as LDMOS gates are sensitive to static discharge despite integrated ESD protection.
The published series-equivalent output impedance tables in the NXP datasheet MRF8S9220H are referenced to the package leads, not the device intrinsic plane. Use these tables as the starting point for matching network synthesis, but expect 1-2 dB gain and efficiency variation between simulation and bench measurement due to parasitic layout effects. For Doherty configurations using the MRF8S9220HR3 variant, maintain 50 Ohm impedance at the combining point with quarter-wave transmission line transformers matched to the load-pull contours.
