MRF7S19080HR3 개요
A lateral N-channel enhancement-mode RF power MOSFET (LDMOS) is a high-power transistor architecture in which the current-carrying channel is oriented laterally along the die, enabling high breakdown voltage, high gain, and excellent ruggedness under severe mismatch (high VSWR). Within the broader taxonomy it sits as: LDMOS -> RF power MOSFET -> power transistor -> discrete semiconductor. LDMOS dominates the cellular base-station PA market from 700 MHz to 2.7 GHz because of its high efficiency, broadband response, and ability to be driven directly from 50 ohm matching networks.
Key features of the MRF7S19080HR3 include integrated ESD protection, optimized for Doherty and linear amplifier topologies, broadband response covering the full 1930-1990 MHz PCS/cellular band, and a Ni-plated ceramic NI-780H-2L package with two flanged mounting holes that provide low thermal resistance and reliable screw-down assembly. Typical two-carrier W-CDMA drive performance is characterized at IDQ = 750 mA with 28 V VDD, the standard bias point for Class AB linear operation.
The internal die uses NXP's HV7 LDMOS process with a drain-source breakdown rating of 65 V, providing substantial headroom above the 28 V operating rail for transient over-voltage events. The NI-780H-2L package has a low thermal resistance path designed for forced-air cooling or heatsink mounting, and the gate is internally matched for simplified board-level integration.
Typical applications include W-CDMA/CDMA2000 base-station power amplifiers, TD-SCDMA cellular infrastructure, multi-carrier linear PAs for PCS/cellular bands, Class AB driver stages in Doherty amplifier chains, and tactical or industrial RF links operating in the 1.9 GHz band. Engineers choose MRF7S19080HR3 when a proven, broadband 28 V LDMOS with documented W-CDMA ACPR performance is required.
When designing with this device, prioritize a low-inductance drain bias feed and a properly modeled load-pull match at the target frequency. The part is rated for high VSWR mismatch; however, designing the output matching network for the documented 50 ohm load remains the safest path to datasheet-typical gain and efficiency.

Its lateral N-channel LDMOS structure provides high ruggedness under antenna-mismatch VSWR events common in field-deployed base stations. Engineers integrate this part into macro-cell and micro-cell PA lineups, often as the final stage after a lower-power driver.

설계 노트
The NI-780H-2L flange is the primary thermal path for the MRF7S19080HR3. At 28 V VDD and 24 W average RF output with 32 % drain efficiency, the part dissipates approximately 51 W of DC power, so the flange MUST be bolted to a heatsink or cold plate using thermal compound. Estimated: with theta_JC of approximately 0.3 C/W and a 50 C/W heatsink-to-ambient thermal resistance, junction temperature rise is roughly 35 C above the heatsink. Insufficient thermal mounting is the most common failure mode for this part.
Use low-inductance drain bias feeds (multiple vias, short traces) to prevent feedback instability at 1.9 GHz. Place gate and drain matching networks on Rogers RO4350B or equivalent low-loss PCB substrate with controlled-impedance (50 ohm) microstrip lines. Keep the input (gate) matching network physically separated from the output (drain) matching network to minimize coupling. Per NXP application notes, the source leads must be bonded directly to the ground plane with maximum via density under the flange.
Do not exceed Vdss = 65 V (including transient overshoot from load-mismatch). Ensure the bias sequencing turns on the gate first (negative voltage, typically -5 V) before applying 28 V VDD, then ramps gate voltage to achieve IDQ = 750 mA. Reverse biasing or fast hot-switching of VDD can cause device failure. Designers should also include a drain voltage clamp or TVS for severe antenna-mismatch conditions, even though the LDMOS part is rated for high VSWR.
For W-CDMA linearity, maintain IDQ = 750 mA within +/-50 mA across the operating temperature range. Drain efficiency drops roughly 0.1 % per 1 C temperature rise at constant IDQ; for thermally stable operation mount a thermistor to the flange for active bias compensation. ACPR at 5 MHz offset is sensitive to bias drift, so closed-loop bias control is recommended for production base-station designs.
