RF Modules
VCOs
For Cellular Phone/Dual Band 8.5x6.5
FEATURES
ELECTRICAL CHARACTERISTICS
PART NO. : QVC811171RT-2094
APPLICATIONS : GSM
• VCO for mobile communication equipment applications.
Roughly 0.7 to 2GHz frequency range, dual mode.
Measuring conditions : Ta=25±2°C Vcc=2.75V
Min.
• Area is greatly reduced (41% less area) in comparison to the
use of two of the earlier type VCOs (QVC80 series, 8.5×5.5mm).
• Compact, low profile and light weight type (L8.5×W6.5×T1.8mm,
210mg typ.).
• Either single output type for low voltage operation, low power
consumption.
