Hi Dear Abdou2014 , You can use 1n4148 (nS) for FM circuit, because
https://en.wikipedia.org/wiki/1N4148_signal_diode
The 1N4148 is a standard silicon switching signal diode. It is one of the most popular and ... the JEDEC nomenclature. The 1N4148 is useful in switching applications up to about 100 MHz with a reverse-recovery time of no more than 4 ns. ( 250 Mhz).
