SO IF YOU'RE IMPATIENT, DO NOT ORDER FROM ME!! Let me repeat that, IF YOU'RE IMPATIENT, DO NOT ORDER FROM ME!!Д®ach radio goes through 24 hours minimum of burn-in testing when it's finished. I BELIEVE IN QUALITY BEFORE QUANTITY! (And from the sales I'm receiving, so do you!) That might help to be prepared when installing the first RFX.YOU ARE REQUIRED TO AGREE TO THESE TERMS IN ORDER TO PURCHASE FROM THIS WEB SITE. In USA these amplifiers are very popular and on the internet you can find many videos and reviews.

#RFX 150 AMPLIFIER INSTALL#

It is necessarilyВ to have good technical knowledge to install RFX types. The RFX85HD is your choice for 10 meter radio repairs and upgrades when all your replacing is the final transistor or no transistors.Д«oth RFX85 units feature the new fan-ready heatsink design and variable bias controls for better tuning on SSB radio installations.

The RFX85HD circuit includes only the final amplifier stage and low pass filter which makes for a much quicker and easier installation.

#RFX 150 AMPLIFIER DRIVER#

The RFX85 is your choice for 10 meter radio repairs and upgrades that require replacing the radioвЂ™s driver and final amplification stages. The RFX85 Circuit includes driver stage, final amplifer stage and low pass filter.

There are now 2 RFX85 Choices: the Standard RFX85 and the New RFX85HD High Drive. However, it is recommended to attach it to the transceiverвЂ™s PCB because some transceivers come equipped with antenna warning systems, or other circuits, that are on ancillary boards between the recommended connection point and the antenna connector. * It is possible to attach the RF OUT coax directly to the antenna connector. G) The incoming receive signal is sampled from C14 and connected to the receive strip of the transceiver through the RFX75вЂ™s coaxial cable marked RX OUT. This is sent to the S-meter detection circuit in the transceiver through the yellow wire.ДЇ) The final RF output signal of the RFX75 is sent back to the radio through the RF OUT coaxial cable where it is connected with the transceiverвЂ™s antenna connector *. The RFX75 mounts to the back of most transceivers with little or no modification to the transceiverвЂ™s chassis.Д«) Once installed, the transmitted RF signal from the output of the transceiverвЂ™s driver stage (or pre-driver stage) is sent to the RFX75 via the coaxial cable marked RF IN.Д¬) The driver signal is then amplified through the RFX75вЂs ERF2030 (FET1) and then again through the ERF7530 (FET2).Д) The amplified signal from the ERF7530 passes through the RFX75вЂ™s efficient low pass filter.Д®) A small portion of the signal is sampled through C19 and rectified through D3 and D4. THEORY OF OPERATION OF POWERBAND TYPES, DESCRIPTION OF RFX75:ДЄ) The RFX75 replaces the transceiverвЂ™s final amplifier stage and low pass filter section.

Most installations will see 75 вЂ“ 100 watts PEP output power. The output power of the RFX75 varies depending on the transceiver that it is installed on. The RFX75 features the latest Power MOSFET technology and a built in S-meter detection circuit.

The RFX75 is a RF final output stage and low pass filter designed as a replacement and/or upgrade for most 10-meter amateur transceivers. RFX75 is an Amplifier, 75 вЂ“ 100 Watt PEP Output Power, RF Final Output Stage and Low Pass Filter, Designed as a replacement and/or upgrade for most 10 meter amateur transceivers.

Under the name POWERBAND, the company PALOMAR in USA sells a line ofД¤ types of high power replacement final amplifier sections with high performance low pass filter for 10 meter amateur transceivers.ДЄfter RFX75 and RFX150 they now introduce the RFX85 and RFX85HD.
