USB FM Radio Design:
High Performance FM Broadcast Radio:
This reference design is intended for FM broadcast radio applications in the 87.5–108 MHz band. For high performance and ruggedness, the design uses Freescale’s MRFE6VP61K25H/HS 50 Volts transistors designed to operate under high voltages and harsh environments. The system is tuned to deliver 1100 watts CW output power. The design comes along with complete documentation such as application notes, hardware design files and datasheets.

Low voltage FM stereo radio:
This reference design describes a low voltage FM radio for portable products such as mobile phone, CD and MP3 players. Via software, the radio can be tuned into the European, Japan or US FM band. The design is based on a single chip stereo FM receiver TEA5767/68 which has low power consumption and small size. The current is about 13mA and the supply voltage can be varied between 2.5 and 5V. The IC does not require any alignment, which makes the use of bulky and expensive external components unnecessary. The digital tuning is based on the conventional phase locked loop (PLL) concept.
