NXP Semiconductors MRFE6P9220HR3

Overview

MRFE6P9220HR3 from Freescale Semiconductor is an N-channel enhancement-mode lateral RF power MOSFET designed for broadband common-source amplifier applications in 28 V base station equipment. It delivers 47 W average output power at 880 MHz under N-CDMA modulation, achieves 20 dB power gain and 30% drain efficiency, and supports 865–900 MHz operation with rugged 10:1 VSWR tolerance at 350 W CW.

For engineers reviewing the MRFE6P9220HR3 datasheet, MRFE6P9220HR3 pinout, MRFE6P9220HR3 application, or MRFE6P9220HR3 equivalent, this device is selected for high-reliability, high-efficiency RF power amplification in cellular infrastructure where thermal robustness, intermodulation linearity, and push-pull configuration stability are critical design requirements.

Technical Context

This device operates as a single-ended, internally matched RF power transistor optimized for push-pull configurations only. Its lateral LDMOS structure enables stable operation up to 225°C junction temperature, with series-equivalent large-signal impedance characterization provided across 850–910 MHz for precise matching network design.

Thermal resistance is specified at 0.25°C/W (junction-to-case, 220 W CW), and ESD protection meets Class 3B HBM, Class C MM, and Class IV CDM per JEDEC standards. The NI-860C3 package (Case 375G-04, Style 1) integrates a flanged metal-ceramic construction for direct heatsink mounting and low-inductance drain connections.

FAQ

What is the maximum recommended drain voltage for MRFE6P9220HR3?

The MRFE6P9220HR3 is qualified for operation up to +66 V_DS and −0.5 V_DS, but its rated application specifies 28 V_DD operation. Freescale explicitly qualifies the device for "up to a maximum of 32 V_DD" in push-pull configuration - exceeding this risks parametric shift and reduced MTTF. Always maintain V_GS within −0.5 to +12 V to avoid gate oxide stress.

Can MRFE6P9220HR3 be used in single-ended amplifier configurations?

No - the MRFE6P9220HR3 is explicitly designed for push-pull operation only, as stated in its datasheet features and functional test conditions. All electrical characteristics, including gain, efficiency, and ACPR, are measured and guaranteed only in balanced push-pull configuration. Single-ended use violates qualification and may result in thermal imbalance, instability, or premature failure.

What does the "R3" suffix indicate in MRFE6P9220HR3?

The "R3" suffix denotes tape-and-reel packaging: 250 units per 56 mm width, 13-inch diameter reel. This format ensures automated placement compatibility and ESD-safe handling. The base part number MRFE6P9220H refers to the die and package configuration; R3 adds packaging and logistics specification without altering electrical or thermal performance.

How is thermal performance validated for MRFE6P9220HR3?

Thermal resistance R_θJC is measured per AN1955 methodology: 0.25°C/W at 220 W CW with case temperature held at 80°C. Freescale provides an online MTTF calculator (accessible via www.freescale.com/rf) that uses junction temperature, bias, and output power to estimate lifetime - for MRFE6P9220HR3 at 28 V, 47 W avg., and 30% efficiency, calculated MTTF exceeds 10⁶ hours.

What are the key impedance values for matching networks with MRFE6P9220HR3?

At 880 MHz, the MRFE6P9220HR3 exhibits series-equivalent source impedance Z_source = 3.59 − j7.07 Ω and load impedance Z_load = 7.41 − j1.19 Ω (balanced push-pull). These values are measured from gate-to-gate and drain-to-drain respectively, and are provided in Table 9 of the datasheet to enable accurate microstrip or lumped-element matching network synthesis without iterative EM simulation.
