23cm 1.2GHz 18W Amp +42.5dBm
This RA-SHF Kit is suitable for use with the RA18H1213G Mitsubishi RA series module to produce up to 18 Watts output on the 23cm 1240 to 1300MHz band. The construction notes supplied are specifically written to suit the specifications of the RA18H1213G 18 Watt module. Mini-Kits currently stock the M suffix modules that have a plastic cover & produce a second harmonic level of -25dBc. The Kit is suitable for both linear SSB, AM & non linear FM modes.
The complete Kit includes all onboard components, double sided through hole plated PC board & comprehensive construction notes. The Kit requires a heat sink, connectors, & miscellaneous hardware to complete.
The 2nd Harmonic from both the 30W M suffix modules are around -25dBc, so you may require a suitable Low Pass Filter 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 asisted Pentium P4 heatsink that can be readily found in surplus computer shops.
