    Sometime back someone asked about a cross for a Motorola custom RF transistor, part number SRF3999. This transistor was used in a number of broadcast transmitter products.

    Motorola sold that line of RF Transistors to MA/COM and the catalog part number is MRF173CQ.

    The datasheet can be found here:

    Cheers!
