I have been given this PA module, is anybody able to help identify it? The pre-driver is a M6S4 the driver amp is a AFT20P060 and the amplifier is a pair of BLF8G22LS-22. The data sheet for the BLF8G22LS-22 give the frequencies from 2110 MHz to 2170 MHz. Not sure how far the frequency could be moved as I would like to use it for DATV on QO-100. Dose anyone have or used one of these?
