You should be able to find data and a circuit on the Philips web site. Details are also in the Maplin catalogue (www.maplin.co.uk). The chip is designed for the VHF/FM broadcast band (~100 MHz), but I have had one working on the 144 MHz amateur band, and you should be able to get it working on 150 MHz.
