NXP Semiconductors MRF101AN-START

Overview

MRF101AN-START from NXP Semiconductors is an evaluation kit for the MRF101AN RF power LDMOS transistor, designed for 1.8–2.0 GHz broadband amplifier applications with 10 W output power capability and integrated thermal management via a 0.7" × 2" baseplate PCB. It supports rapid prototyping of HF/VHF/UHF RF power stages in lab and development environments.

For engineers reviewing the MRF101AN-START datasheet, MRF101AN-START pinout, MRF101AN-START application, or MRF101AN-START equivalent, this kit provides verified mechanical mounting hardware, SMA RF interfaces, stainless steel fasteners, and a pre-configured thermal baseplate to accelerate RF power amplifier design validation and impedance matching trials.

Technical Context

The MRF101AN-START kit centers on the MRF101AN - a 10 W, 1.8–2.0 GHz RF power transistor in TO-270-2 Widebody package - mounted on a rigid 0.7" × 2" (1.8 cm × 5.1 cm) aluminum baseplate PCB with integrated thermal path. The board includes two SMA connectors for RF input/output, spring lock washers (#2 and #4), rectangular aluminum washers (0.40" × 0.220" × 0.0625"), and stainless steel machine screws (4-40 × 5/16", 2-56 × 1/4").

No active circuitry or bias control is included; the kit serves strictly as a mechanical and thermal evaluation platform. All fasteners and interface hardware are specified for repeatable, low-EMI mounting in RF test benches and prototype amplifiers.

FAQ

What is the MRF101AN-START used for?

The MRF101AN-START is an evaluation kit for the MRF101AN RF power transistor, providing a mechanically validated platform with SMA connectors, thermal baseplate, and mounting hardware. It enables rapid characterization and impedance tuning of 1.8–2.0 GHz RF power amplifier stages without custom PCB fabrication. The MRF101AN-START supports lab-based RF performance validation and thermal interface testing.

Does the MRF101AN-START include the MRF101AN transistor?

Yes, the MRF101AN-START includes the MRF101AN RF power LDMOS transistor pre-mounted on the 0.7" × 2" baseplate PCB. The transistor is soldered in place and ready for RF signal injection and thermal measurement. No additional assembly or device placement is required to begin evaluation of the MRF101AN-START.

What RF connectors are provided on the MRF101AN-START?

The MRF101AN-START features two SMA connectors: one for RF input and one for RF output, both mounted directly on the 0.7" × 2" baseplate PCB. These enable direct 50 Ω connection to vector network analyzers, signal generators, and spectrum analyzers during MRF101AN-START evaluation.

Are all mounting components included with the MRF101AN-START?

Yes, the MRF101AN-START includes complete mechanical mounting hardware: stainless steel pan-head Phillips machine screws (4-40 × 5/16" and 2-56 × 1/4"), stainless spring lock washers (#2 and #4), and an aluminum rectangular washer (0.40" × 0.220" × 0.0625"). These ensure secure, low-EMI attachment of the MRF101AN-START baseplate to heatsinks or test fixtures.

Is bias circuitry included on the MRF101AN-START PCB?

No, the MRF101AN-START PCB contains no active bias circuitry, decoupling networks, or matching components. It is a passive mechanical and thermal evaluation platform. External DC bias, gate control, and RF matching must be supplied externally when using the MRF101AN-START to evaluate the MRF101AN transistor.
