MRF6V14300HS 概要
An RF power MOSFET is a lateral metal-oxide-semiconductor field-effect transistor optimized for radio-frequency power amplification rather than low-frequency switching. Within the taxonomy it belongs to: RF power transistor -> discrete RF semiconductor -> power management discrete -> semiconductor device. Lateral construction gives lower feedback capacitance and higher breakdown ruggedness than vertical DMOS parts, enabling safe operation into high VSWR loads typical of pulsed radar service.
Key features of the MRF6V14300HS include 18 dB minimum power gain at 1400 MHz, 50 V typical drain bias, integrated gate-source ESD protection, gold metallization for hermetic reliability, and a beO-free package construction. The part is internally matched for broadband performance in the 1200 to 1400 MHz L-band segment and includes built-in protection against high VSWR conditions.
Architecturally, the MRF6V14300HS uses NXP's HV6 lateral MOSFET process, a high-voltage enhancement-mode LDMOS-derivative technology tuned for RF power. The ceramic NI-780S flange package provides low thermal resistance and beO-free construction, supporting long-term reliability in pulsed avionic and military environments where beO is restricted for health and safety reasons.
Typical applications include L-band avionics transponders, DME (Distance Measuring Equipment), TACAN, primary surveillance radar, IFF (Identification Friend or Foe) transmitters, and pulsed RF power amplifiers for the 1030/1090 MHz secondary surveillance band when paired with appropriate matching networks. The beO-free package is particularly valued in aerospace and defense programs.
When designing with this part, ensure adequate DC blocking and RF bypassing on the gate and drain bias lines. The duty cycle must remain within the 1% to 12% specification envelope to avoid exceeding the pulsed thermal safe operating area. Source grounding via the package flange is critical for low common-lead inductance.

主な用途
MRF6V14300HS の用途: 6 件s: L-Band Avionics Transponders, DME / TACAN Ground Transmitters, Primary Surveillance Radar (PSR), IFF (Identification Friend or Foe) Transmitters, Pulsed RF Power Amplifier Modules, Legacy RF Power Amplifier Sustainment.
L-Band Avionics Transponders
The MRF6V14300HS is well suited for L-band avionics transponders operating at 1030/1090 MHz (secondary surveillance radar) when matched into the 1200 to 1400 MHz band. Its 330 W pulsed output power, 18 dB gain at 50 V bias, and 1% to 12% duty cycle envelope match the short-pulse, high-power requirements of Mode S and ATCRBS transponder transmitters. The beO-free NI-780S ceramic package meets aerospace health-and-safety requirements. Paired with a 50 V drain modulator and 100 us pulse width, the part delivers the 330 W peak envelope power needed for ground interrogation while remaining within the pulsed thermal safe operating area.
おすすめ
DME / TACAN Ground Transmitters
Distance Measuring Equipment (DME) and TACAN ground beacons rely on pulsed RF power amplifiers in the 962 to 1213 MHz band, where the MRF6V14300HS can be retuned with appropriate matching networks to deliver the required 330 W peak envelope power. The 50 V VHV6 lateral MOSFET architecture provides excellent ruggedness into high VSWR loads typical of aircraft antenna reflections, and the 1% to 12% duty cycle envelope matches the DME interrogation pulse train. The beO-free NI-780S flange package simplifies environmental compliance for FAA and ICAO ground-station installations.
おすすめ
Primary Surveillance Radar (PSR)
Long-range primary surveillance radars operating in the 1.2 to 1.4 GHz L-band segment use high-power pulsed transmitters where the MRF6V14300HS provides 330 W of output power per device. With driver stages based on lower-power NXP VHV6 parts, the HS variant serves as the final amplifier in coherent and non-coherent radar chains. The 18 dB gain reduces driver-chain complexity, and the 50 V bias supports long pulse widths typical of long-range surveillance. Integrated VSWR protection and beO-free packaging are valued for field-deployed radar installations.
おすすめ
IFF (Identification Friend or Foe) Transmitters
Military IFF interrogators operating in the 1030 MHz band benefit from the MRF6V14300HS pulsed output capability when the device is matched slightly off-tune from its 1400 MHz center. The 330 W peak power supports long interrogation ranges required by Mode 5 and Mode S military transponder protocols, and the 50 V VHV6 process provides the ruggedness needed for the harsh electromagnetic environment of military platforms. The beO-free NI-780S package is mandatory for many defense programs that restrict beryllium-bearing materials.
おすすめ
Pulsed RF Power Amplifier Modules
Custom pulsed RF power amplifier modules for industrial and scientific applications use the MRF6V14300HS as the final stage where 330 W peak envelope power is required at L-band frequencies. The 18 dB gain simplifies the driver chain, and the 50 V drain bias allows direct compatibility with standard 48 V telecommunications rails stepped up via a PFC front end. The part's 1% to 12% duty cycle envelope suits particle accelerator RF sources, plasma heating systems, and pulsed NMR amplifiers.
おすすめ
Legacy RF Power Amplifier Sustainment
Military and aerospace sustainment programs with deployed L-band transmitter systems rely on the MRF6V14300HS as the OEM-specified replacement part for end-of-life amplifier modules. Field service depots use this part to maintain operational readiness of legacy transponder, DME, and TACAN systems where redesign is not cost-effective. Rochester Electronics and authorized distributors stock the HS variant specifically to support these long-life sustainment contracts spanning 20+ years of platform service life.

設計ノート
The NI-780S ceramic flange package requires a properly torque-bolted heatsink with thermal compound to maintain junction temperature within the pulsed SOA envelope. Estimated: at 330 W pulsed output, 50 V drain, and 12% duty cycle, the device dissipates roughly 50 to 80 W average. The beO-free ceramic has a thermal resistance of approximately 0.4 C/W junction-to-flange, so the heatsink must keep flange temperature below 70 C for reliable long-term operation. Inadequate heatsinking is the primary failure mechanism for this part family.
Mount the MRF6V14300HS directly to the chassis with short, low-inductance source-ground straps. The NI-780S flange is the primary source connection - any inductance here degrades gain and stability. Use a microstrip or stripline matching network on a low-loss substrate (Rogers RO4350B or RT/duroid 5880 recommended) placed within 5 mm of the drain lead. DC blocking on the RF input/output and RF chokes on the drain and gate bias lines are mandatory.
Do not operate the MRF6V14300HS in continuous-wave (CW) mode at full 330 W output - the duty cycle is strictly limited to 1% to 12% pulsed. Exceeding 12% duty cycle or attempting CW service will cause thermal runaway. Also avoid static discharge on the gate; the VHV6 process is ESD-sensitive (Class 1A typical) and requires handling precautions. Use gate-source protection diodes for high-inductance bias circuits.
The gate and drain bias feedthroughs must be well decoupled with 100 pF and 10 nF ceramic capacitors in parallel, placed within 3 mm of the bias pins. Series gate resistors (10 to 100 ohm) dampen parasitic oscillations. Provide a 50 ohm microstrip launch at both RF ports with minimal via count; the NI-780S lead geometry is asymmetric, so the input/output layout should mirror the datasheet reference design exactly for stability above 1.3 GHz.
