NXP Semiconductors MRF6P3300HR5

Overview

MRF6P3300HR5 from NXP Semiconductors (formerly Freescale) is an N-channel enhancement-mode lateral RF power MOSFET designed for broadband large-signal common-source amplifier operation in 32 V analog/digital TV transmitters. It delivers 270 W PEP at 860 MHz with 20.2 dB power gain, 44.1% drain efficiency, and handles 10:1 VSWR at 300 W CW - optimized for push-pull DVB-T, ATSC, and PAL B/G broadcast applications.

For engineers reviewing the MRF6P3300HR5 datasheet, MRF6P3300HR5 pinout, MRF6P3300HR5 application, or MRF6P3300HR5 equivalent, key selection criteria include its 470–860 MHz frequency range, 32 V DC operation limit, internally matched 5-pin NI-860C3 package, and verified performance under high-VSWR and OFDM modulation conditions.

Technical Context

This device operates as a single-ended or push-pull RF power amplifier stage in broadband transmitter final stages. Its lateral LDMOS structure supports high peak-envelope power (PEP) handling up to 270 W and continuous-wave output up to 300 W at 860 MHz, with thermal resistance R_θJC of 0.23°C/W at 300 W CW.

The MRF6P3300HR5 is characterized with series-equivalent large-signal impedance parameters (e.g., Z_source = 4.22 − j6.38 Ω, Z_load = 5.18 − j0.58 Ω @ 860 MHz), enabling precise external matching network design. It features integrated ESD protection rated Class 3B HBM, and is qualified only for push-pull configuration - not usable as a single-ended switch or driver.

FAQ

What is the maximum safe operating voltage for the MRF6P3300HR5?

The MRF6P3300HR5 has a maximum drain-source voltage rating (V_DSS) of +68 Vdc, but its qualified operating voltage is strictly limited to 32 Vdc per datasheet specifications. Exceeding 32 Vdc in functional operation risks premature failure, violates qualification limits, and voids reliability guarantees. The 68 Vdc rating applies only to non-operational stress testing.

Can the MRF6P3300HR5 be used in single-ended amplifier configurations?

No - the MRF6P3300HR5 is explicitly designed for push-pull operation only, as stated in its Freescale documentation. Using it in single-ended mode violates its qualification, compromises linearity and thermal performance, and may cause instability or catastrophic failure due to unbalanced internal structure and asymmetric parasitics.

What does the 'R5' suffix indicate in MRF6P3300HR5?

The 'R5' suffix denotes tape-and-reel packaging: 50 units per 13-inch reel on 56 mm carrier tape. This format supports automated pick-and-place assembly in high-volume broadcast module manufacturing. The alternative 'R3' suffix indicates 250 units per reel - used for lower-volume or prototyping scenarios.

How is thermal management implemented for the MRF6P3300HR5 in production designs?

The MRF6P3300HR5 uses a flanged NI-860C3 package with direct-mount thermal interface. Production designs require low-thermal-resistance mounting (e.g., thermal paste + torque-controlled screws) to a copper heatsink, with case temperature maintained ≤80°C at 300 W CW to achieve the specified R_θJC = 0.23°C/W and ensure MTTF >1 million hours.

Is the MRF6P3300HR5 RoHS compliant and lead-free?

Yes - the MRF6P3300HR5 is fully RoHS compliant per Directive 2011/65/EU and manufactured with lead-free terminations and packaging. Its datasheet explicitly states RoHS compliance, and material declarations confirm absence of restricted substances including Pb, Cd, Hg, Cr(VI), PBB, and PBDE.
