Hi been to a local radio ralley and bought a nice looking ex mod board for £1 (2USD) and found that its a an amplifier for 400-470mhz (board marked as such but tuned somewhere I would have thought. The chip inside is a single chip that is marked as 'TRW Bordeaux France MX7,5-3 2.2880' anyone have any information on this chip at all, voltages, current input/output power etc? many thanks regards Gus M0IKB
