150 Ė 200 Watt OEM Final Amplifier Section
with High Performance Low Pass Filter


Download Manual


The RFX150 is a replacement part for 10 meter amateur transceivers. The RFX150 includes the RF final output stages and low pass Filter section for a 10 meter mobile amateur

The RFX150 uses a matched pair of ERF7530 75W RF Power MOSFET from EKL Components

  • Unique Vertical Fin Design Maximizes Heat Dissipation
    Itís physics 101, heat rises. So why would anyone design a heat sink
    with horizontal or downward pointing ns! In lower power applications
    this may be okay, but when dealing with hundreds of watts in
    a mobile environment you need every advantage possible. That is
    why the RFX150 features a radically unique design with vertical
    upward pointing cooling ns. The ns extend past the transceiverís
    top cabinet to allow increased air flow to the heat sink.
  • Latest Technology MOSFETís in an Old School Circuit
    The RFX150 uses a matched pair of ERF7530 high power MOSFET RF
    transistors running Class AB. The familiar push-pull design features
    time-tested components such as broadband transformers and
    dipped mica capacitors.
  • Made to Last
    Heavy-Duty Power Cord with SAE Connectors and Weatherproof
    Fuse Holder
  • Fan Kit Ready
    The RFX150 ns are drilled and channeled for easy mounting of the
    optional fan kit. Available separately. (coming soon).
  • 5-3/8" wide (across the back panel of the radio) x 2-1/4" deep (how far it sticks off the back of the radio) x 2-1/2" tall.  The fins are designed to extend past the top cabinet of the radio.

The RFX-150 and the SX-175 both contain the same amplifiers inside. The only difference is the size of the heatsink (fins) on each one of them. I don't know why they decided to call one the 175 and the other a 150. Both have the same electronics inside.

Think of the RFX-150 as light duty and the SX- 175
as heavy duty as far as talk time before overheating. If you talk a lot and use SSB a lot, then the SX-175 is best. If you listen a lot and use mostly AM, then the RFX-150 will do fine.
