NXP Semiconductors MRFE6S9160HSR3

Overview

MRFE6S9160HSR3 from NXP Semiconductors (formerly Freescale) is an N-channel enhancement-mode lateral RF power MOSFET designed for base station multicarrier amplifier applications in 865–960 MHz bands. It delivers 35 W average output power at 880 MHz under N-CDMA modulation, with 21 dB power gain, 31% drain efficiency, and −46.8 dBc ACPR at ±750 kHz offset - optimized for GSM, N-CDMA, and EDGE infrastructure transmitters.

For engineers reviewing the MRFE6S9160HSR3 datasheet, MRFE6S9160HSR3 pinout, MRFE6S9160HSR3 application, or MRFE6S9160HSR3 equivalent, key selection criteria include ruggedness under 10:1 VSWR at 32 Vdc, internal input matching, RoHS-compliant NI-780 package, and verified thermal resistance of 0.33 °C/W at 35 W CW operation.

Technical Context

This device operates as a high-efficiency RF power amplifier stage in cellular base station final output stages. Its lateral LDMOS architecture supports 28 V DC supply, 1200 mA quiescent drain current, and is characterized with series-equivalent large-signal impedance parameters (e.g., Z_source = 1.26 + j0.15 Ω, Z_load = 0.64 − j1.05 Ω at 880 MHz), enabling stable broadband matching across 865–960 MHz.

Thermally, it features a maximum junction temperature of 225 °C and case temperature limit of 150 °C, with validated ruggedness to handle 10:1 VSWR at 32 Vdc and 3 dB overdrive. Integrated ESD protection meets HBM Class 1A, MM Class A, and CDM Class IV per JESD22 standards.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous drain voltage rating for MRFE6S9160HSR3?

The MRFE6S9160HSR3 has a maximum drain-source voltage rating (V_DSS) of +66 V_DC, with a minimum of −0.5 V_DC. This allows safe operation at the recommended 28 V_DC supply with substantial margin for transient overvoltage events common in base station environments. The device is qualified for continuous use up to 32 V_DC.

Does MRFE6S9160HSR3 require external input matching components?

No, MRFE6S9160HSR3 is internally matched for 50 Ω input impedance across its 865–960 MHz operating band. The datasheet confirms this in Table 4 footnote "Part is internally matched on input," and Figure 16 shows measured Z_source values near 1.26 + j0.15 Ω at 880 MHz - enabling direct integration into 50 Ω test fixtures and production circuits without gate matching networks.

What is the thermal resistance (R_θJC) of MRFE6S9160HSR3 under typical operating conditions?

MRFE6S9160HSR3 has a thermal resistance of 0.33 °C/W when operated at 35 W CW with case temperature maintained at 73 °C, as specified in Table 2. This value is measured under standardized conditions and enables accurate junction temperature estimation using T_J = T_C + (P_diss × R_θJC), critical for reliability validation in base station thermal designs.

Can MRFE6S9160HSR3 withstand antenna VSWR mismatches in deployed base stations?

Yes, MRFE6S9160HSR3 is explicitly characterized to handle 10:1 VSWR at 32 V_DC, 880 MHz, and 3 dB overdrive - a key ruggedness specification for cellular infrastructure transistors. This capability is validated per industry-standard test methods and ensures survivability during antenna cable faults, connector corrosion, or environmental detuning without device failure.

What ESD protection level does MRFE6S9160HSR3 provide on its gate terminal?

MRFE6S9160HSR3 provides integrated ESD protection rated at Human Body Model (HBM) Class 1A (≥250 V), Machine Model (MM) Class A (≥100 V), and Charge Device Model (CDM) Class IV (≥1000 V), per Tables 3 and 4. This eliminates the need for external gate ESD clamps in most RF front-end layouts and improves manufacturing yield during SMT assembly.
