Engineering Application Notes & Builder FAQ

Compatible Active RF Devices: Engineered for MRF433 / MRF426 operating at 12V / 28V DC across 1.6-30 MHz (20W output).

Recommended Thermal Management: Pair this module with our Model 55HS machined heatsink assembly for reliable continuous duty-cycle dissipation.

Spectral Purity & Harmonic Filtering: For amateur radio and commercial broadcast compliance, follow the amplifier output with an appropriate 50-ohm low-pass harmonic filter (such as our FL1 series for HF).

Key Engineering Highlights

  • Verified RF Performance: Inspected and kitted to meet strict solid-state HF, VHF, and UHF operating standards.
  • Drop-In Compatibility: Ideal for Motorola application note builds, commercial transmitter maintenance, and custom linear pallet designs.
  • No Minimum Order Quantities: Fast domestic and international shipping with most orders shipping in under 1 week.
