MD7P19130HSR3 Overview
An RF power MOSFET is a lateral field-effect transistor optimized for high-frequency, high-power amplification in the megahertz-to-gigahertz range. RF power MOSFETs sit at the top of the power amplifier hierarchy (RF amplifier -> power amplifier -> RF front-end -> wireless base station) and are characterized by output power (W), gain (dB), drain efficiency (%), and adjacent-channel leakage ratio (ACLR, dBc). Compared with bipolar RF transistors, LDMOS offers higher gain, simpler biasing, better thermal stability, and intrinsic matching to 50 ohm systems. MD7P19130HSR3 is the WCDMA-optimized "S" suffix variant, distinguished by tighter linearity for 3GPP signal chains.
Key features include 20 dB typical power gain at 1987.5 MHz, 30% drain efficiency at full output, -36 dBc ACPR at 5 MHz offset in 3.84 MHz W-CDMA channels, and a 7.5 dB peak-to-average ratio (PAR) handling capability. The device is designed for single-carrier operation and includes integrated ESD protection and a thermally enhanced ceramic package capable of dissipating the full 40 W average output continuously when mounted on an adequate heatsink. The 28 V drain bias simplifies integration with existing -48 V telecom plant topologies stepped down through a single DC-DC converter.
The MD7P19130HSR3 is the recommended part for the Doherty final stage and single-ended PA in 1.93-1.99 GHz band (US PCS, UMTS band II) base-station radios. Designers also use it as a driver for higher-power LDMOS finals when additional output headroom is required.
Mounting is straightforward but thermally demanding: the NI-780S-4L package must be bolted to a heatsink with thermal compound, and the RF leads form a 50 ohm microstrip interface. A complete bias sequence (VGGS on before VDDS) is required to prevent device damage, and the input/output match must be optimized for the target frequency sub-band for full W-CDMA ACLR compliance.

Typical Applications
MD7P19130HSR3 is suitable for 6 applications: UMTS Band II Base-Station Final Stage, Doherty Power Amplifier for W-CDMA, Single-Ended PA Driver Stage, Repeater and Small-Cell Power Amplifier, Public-Safety Band II Amplifier, Industrial RF Heating and Plasma Generator.
UMTS Band II Base-Station Final Stage
The MD7P19130HSR3 is the reference final-stage LDMOS for 1.93-1.99 GHz UMTS band II (US PCS) base-station power amplifiers. With 40 W average output at 20 dB gain and 30% drain efficiency from a 28 V rail, it meets 3GPP release-99/5 emission masks (-36 dBc ACPR at 5 MHz offset) without external digital predistortion in many designs. The NI-780S-4L ceramic package bolts directly to the PA heatsink and the input/output microstrip interface simplifies 50 ohm matching. Designers use the part in single-ended PAs for small cells and macro base stations where its 7.5 dB PAR handling preserves ACLR margin under real-world W-CDMA loading.
Recommended
Doherty Power Amplifier for W-CDMA
In a two-way Doherty configuration for UMTS band II, the MD7P19130HSR3 serves as both the carrier (main) and peaking amplifier device. Its 6 dB output PAR and 20 dB gain match the Doherty load modulation profile, allowing the designer to reach >40% system efficiency at 6 dB back-off from 40 W peak. Combined with a 90-degree offset line and harmonic-tuned matching networks, the part delivers -36 dBc ACPR and -55 dBc at 10 MHz offset to meet 3GPP spectrum-emission requirements. The identical die in both carrier and peaking positions simplifies bias sequencing and reduces BOM cost in macro-cell Doherty PA modules.
Recommended
Single-Ended PA Driver Stage
The MD7P19130HSR3 is deployed as a driver stage for higher-power LDMOS final PAs in stacked base-station amplifier chains. Its 20 dB gain and 40 W output cleanly drive 80-100 W finals when paired with an inter-stage attenuator and matching network, with the 30% drain efficiency minimizing thermal load in the driver compartment. The same NI-780S-4L footprint as the finals simplifies PCB layout and allows a common heatsink assembly, reducing mechanical complexity in the radio unit.
Recommended
Repeater and Small-Cell Power Amplifier
For 1.93-1.99 GHz indoor small cells, pico repeaters, and RF boosters, the MD7P19130HSR3 provides the necessary 40 W output power in a compact NI-780S-4L ceramic package that integrates with a small heatsink. Its single-carrier W-CDMA tuning simplifies the digital front end and its 28 V drain rail is compatible with the small-cell PoE+48 V input stepped down through a single DC-DC converter. The part's ACPR margin allows operation without DPD, lowering FPGA/DSP cost in low-channel-count small-cell designs.
Recommended
Public-Safety Band II Amplifier
Public-safety LTE infrastructure operating in the 1.93-1.99 GHz band uses the MD7P19130HSR3 as a final-stage amplifier for mission-critical P25/LTE base stations. Its -36 dBc ACPR margin and 7.5 dB PAR handling support the high crest-factor signals of LTE public-safety waveforms, while the ceramic NI-780S-4L package meets the long-lifetime reliability requirements of emergency-services infrastructure. The bolted ceramic lid resists thermal cycling and vibration in tower-top installations.
Recommended
Industrial RF Heating and Plasma Generator
Industrial RF heating and plasma-generation systems operating in the 1.93-1.99 GHz ISM-adjacent band can use the MD7P19130HSR3 as a continuous-duty power source. Its 40 W average output and 30% efficiency from a 28 V rail provide the energy density needed for plasma ignition and dielectric heating, while the NI-780S-4L bolted ceramic package withstands the high ambient temperatures of industrial enclosures. Designers add harmonic filtering at the output to meet industrial EMC standards.

Design Notes
At 40 W output with 30% drain efficiency from a 28 V rail, approximately 93 W is dissipated as DC heat in the MD7P19130HSR3 junction. The NI-780S-4L ceramic flanged package must be bolted to a heatsink with thermal compound; target a system thermal resistance below 0.3 C/W to keep Tj below 200 C. Estimated: Pdiss = (Pout/eta) - Pout = (40/0.30) - 40 = 93 W. Inadequate heatsinking will cause the device to enter thermal compression and degrade ACPR.
Gate-bias sequencing is mandatory: VGGS must be applied before VDDS to prevent the LDMOS from drawing uncontrolled current during turn-on. Use a sequencer IC or discrete RC network that delays VDDS by 10-50 ms after VGGS reaches the -2.5 V gate-bias threshold. Quiescent current (IDQ = 1250 mA) must be held within +/-50 mA to preserve -36 dBc ACPR per the NXP datasheet.
The NI-780S-4L input and output leads form a 50 ohm microstrip interface that must transition smoothly to the PCB substrate. Use Rogers RO4350B or RO4003C dielectric for the input/output matching networks to minimize loss at 1.9 GHz; FR-4 adds ~0.5 dB loss per match. Keep the gate-bias trace perpendicular to the RF path and decouple VGGS with a 10 uF tantalum plus 0.1 uF ceramic right at the package lead to prevent low-frequency oscillation.
Do not exceed 65 V VDS - transient spikes from drain-feed inductance can punch through the LDMOS even within the SOA curve. Add a 10 uF + 1 uF + 0.1 uF decoupling stack at the VDDS lead with low-ESR ceramic capacitors. Never operate the part without RF input - open-input conditions cause excessive voltage stress and can permanently damage the gate oxide. Add an isolator or load-mismatch protection circuit at the output for production deployments.
