RF Modules
VCOs
For Cellular Phone/Single Band 8.5x6.5
QVC81 Series
High Power Type
FEATURES
VCO for mobile communication equipment TX (sending) appli-
cations. Roughly 0.5 to 2GHz frequency range, high power.
Occupation area of component can be reduced because exter-
nal pre-amp is not needed.
Compact, low profile and light weight type (L8.5
×
W6.5
×
T1.8mm,
210mg typ.).
Low voltage operation, low current consumption.
Makes cost reduction possible.
