This RA-VHF Mitsubishi amplifier Kit is suitable for most RA series modules up to 60W that use either the HS2 or H2M package. The construction notes supplied are specifically written to suit the specifications of the RA30H1317M1 30 Watt module. Mini-Kits currently stock the M1 suffix modules that have a metal cover and produce a second harmonic level of -35dBc. The Kit is suitable for both linear SSB, AM and non linear FM modes.  This Kit is also suitable for the 60 Watt RA60H1317M, 80 Watt RA80H1415M1, RA30H2127M and similar frequency range modules.  The 2nd Harmonic from the metal cased M1 suffix modules are around -35dBc, so you may require a suitable Low Pass Filter like the LPF7-170M Kit to comply with local country regulations.

Please Note: For most applications using FM, You will require a large Heat sink with at least a rating of 0.67 degrees C per watt. Mini-Kits suggests the use of a fan assisted Pentium P4 heat-sink that can be readily found in surplus computer shops. 

The Product image shows a fully constructed Module board without the optional Mitsubishi module.  Please refer to the Options Tab for the descriptions of the various products available.

RA-VHF KIT1 is a Basic Kit that includes the PC board, Instructions, and all on board components.  Requires complete construction and soldering of SMD components.

RA-VHF-B is a fully constructed untested Module board.  Not always available depends on workload.

RA-VHF PCB Only includes the PC board and Kit construction notes.

Modules Option: These are the available modules that suit this Kit.  Please select the type when ordering the Kit.

Kits and Modules Do Not include the RF module, heat-sink, connectors or miscellaneous hardware.  If you want to use this Kit with modules with a different frequency range, then you will have to modify the Low Pass Filter to suit.

For advanced constructors Only.
