NXP Semiconductors MRF7S15100HR5

Overview

MRF7S15100HR5 from NXP Semiconductors (formerly Freescale) is an N-channel enhancement-mode lateral RF power MOSFET designed for CDMA and W-CDMA base station final-stage amplification in the 1470–1510 MHz band. It delivers 23 W average output power at 28 V, 600 mA quiescent drain current, with 19.5 dB power gain and 32% drain efficiency under single-carrier W-CDMA conditions. Its rugged 10:1 VSWR tolerance supports reliable operation in deployed cellular infrastructure.

For engineers reviewing the MRF7S15100HR5 datasheet, MRF7S15100HR5 pinout, MRF7S15100HR5 application, or MRF7S15100HR5 equivalent, key selection criteria include guaranteed 100 W CW P1dB, integrated ESD protection (HBM Class 1C), internal input/output matching, −6.0 to +10 V gate-source voltage range, and NI-780 package thermal resistance of 0.65 °C/W (at 55 W).

Technical Context

This device employs a laterally diffused MOS (LDMOS) structure optimized for high-efficiency, high-linearity RF power amplification in Class AB and Class C configurations. Its internally matched 50 Ω input and output enable simplified PCB layout without external matching networks across the 1470–1510 MHz band.

Characterized using series-equivalent large-signal impedance parameters (e.g., Z_source = 2.62 − j4.97 Ω, Z_load = 3.45 − j3.65 Ω at 1490 MHz), it supports Doherty amplifier architectures and withstands 32 Vdc continuous operation with 10:1 VSWR at 1490 MHz and 100 W CW.

FAQ

What is the maximum continuous drain voltage rating for the MRF7S15100HR5?

The MRF7S15100HR5 has a maximum drain-source voltage (V_DSS) rating of +65 Vdc, with a minimum of −0.5 Vdc. This allows safe operation under transient voltage spikes common in base station power supplies, while the −0.5 Vdc lower limit prevents accidental reverse-bias damage during turn-on sequencing. The device is rated for continuous 32 Vdc operation at the drain terminal.

Does the MRF7S15100HR5 require external input/output matching networks?

No-the MRF7S15100HR5 is internally matched for 50 Ω operation across the 1470–1510 MHz band. Freescale's characterization data confirms input return loss of −15 dB and stable S-parameters without external tuning components. However, the test circuit in the datasheet (Figure 1) includes microstrip lines for PCB transition; these are not matching elements but controlled-impedance interconnects.

What is the gate threshold voltage range for the MRF7S15100HR5?

The MRF7S15100HR5 has a gate threshold voltage (V_GS(th)) range of 1.2 Vdc to 2.7 Vdc, measured at V_DS = 10 Vdc and I_D = 174 μAdc. This tight distribution ensures consistent turn-on behavior across production lots, critical for stable Class AB biasing at 600 mA I_DQ. The typical gate quiescent voltage (V_GS(Q)) is 2.7 Vdc under operating conditions.

How does the MRF7S15100HR5 perform under W-CDMA signal compression?

Under single-carrier W-CDMA (3.84 MHz BW, 7.5 dB PAR), the MRF7S15100HR5 delivers 23 W avg. output with 6.2 dB output PAR at 0.01% CCDF probability, 19.5 dB power gain, and −38 dBc ACPR at ±5 MHz offset. Its PAR compression curve shows −1 dB compression at 24.14 W, confirming robust linearity for real-world base station signals.

Is the MRF7S15100HR5 RoHS compliant and halogen-free?

Yes-the MRF7S15100HR5 is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. The NI-780 package uses lead-free solderable terminations and environmentally compliant ceramic/metal construction, meeting telecom industry sustainability requirements for base station hardware deployed globally.
