MRF300AN-27MHZ

Overview

The MRF300AN-27MHZ is a reference circuit board designed for evaluating the NXP MRF300AN RF Power LDMOS Transistor. It provides a standardized test environment operating at 27 MHz with a 50 Vdc supply. The board facilitates characterization of the transistor's performance, including output power, gain, and efficiency, under continuous wave conditions. It supports linear application development and ruggedness testing within HF and VHF communication systems.

Feature Summary

• Provides a dedicated 27 MHz evaluation platform for the MRF300AN device
• Includes pre-characterized component layout and impedance matching networks
• Supports verification of linear amplifier performance metrics
• Facilitates assessment of device ruggedness under specified load mismatch conditions

Applications

• Industrial, Scientific, and Medical (ISM) equipment development
• HF and VHF radio communication system prototyping
• Broadcast transmitter design validation
• Linear RF power amplifier testing and optimization

Procurement Notes

Verify that the order specifies the complete reference circuit board rather than the discrete transistor alone. Confirm compatibility with standard 50 ohm test fixtures. Ensure handling procedures account for the sensitivity of the onboard LDMOS component to electrostatic discharge during installation or testing.

Selection Notes

Select this reference circuit when specific performance data at 27 MHz is required for the MRF300AN. It eliminates custom matching network design time for initial evaluations. Use it to validate thermal management and biasing configurations before integrating the transistor into final production hardware designs.

Part Context

This item belongs to the MRF300AN series of wideband RF power LDMOS transistors. The series includes mirror pinout versions (A and B) to simplify push-pull configurations. The MRF300AN variant features Gate-Pin 1, Source-Pin 2, and Drain-Pin 3 in a TO-247-3L package, ensuring compatibility with standard mounting practices for high-power RF applications.

Replacement Considerations

MRF300BN-27MHZ serves as the functional equivalent with reversed pinout for push-pull symmetry. Other frequency-specific variants include MRF300AN-13MHZ, MRF300AN-40MHZ, MRF300AN-50MHZ, MRF300AN-81MHZ, and MRF300AN-144MHZ for different operational bands.
