Description
The V42100 is a fundamental single ended oscillator designed for
use in cost sensitive wireless applications. The VCO integrates a
bipolar transistor, varactor diode and high Q resonator in a surface
mount package. The standard SMT packaging provides electrical
shielding and easy PCB assembly. The circuit design and com-
ponent device selection have been optimised for low phase noise
and highly linear tuning performance.
M/A-COM VCOs are manufactured in facilities using advanced
surface mount assembly and automated electrical test equipment.
This ensures consistent electrical performance and product quality
over volume manufacturing quantities.
