DATA SHEET
DS04-21713-1E
ASSP for Mobile Telephone
VCO
(800 to 2000 MHz)
VC-24 Series
s
DESCRIPTION
With excellent C/N characteristics and low current consumption, this VCO series is suitable for use with GSM and
DCS and is ideal to miniaturize dual-band mode products. The VC-24 series can be used in any frequency band
in the 800 MHz to 2000 MHz range. The device utilizes FUJITSU MEDIA DEVICE’s high-frequency design
technology, high-density mounting technology, and frequency adjustment technology to provide a high level of
reliability in addition to high performance and small size.
