You have an old pcb of a mobile phone with some desireable parts. With the help of a hot air blower it´s very easy to remove them without destroying. Just heat the pcb from downside (!) while grabbing the part with a gripper.
Some tips: -Do this outside. Perhaps unhealthy smells... -Test the procedure with some not so precious parts first -Remove all parts of the pcb´s downside which are not important for you and that might disturb airflow.

Look at the leads. All the parts are ok! So this expands possibilities...
Two special parts of interest: The well known PF08103A dual band amplifier from Hitachi/Renesas (at the photo a little dark) and the "921-1840" (it´s from an old Alcatel HE1 phone) vco from TDK (http://tdk-ninebig.com.tw/) . It really seems to be a dual band vco Look at the offered parts at http://www.rfcandy.com/ and compare! (Ok, i own some QVC12 anyway ).
