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.

1. Exceeding these limits may cause permanent damage.
2. Static sensitive, observe appropriate handling precautions.
3. An external series resistor and bypass capacitor will allow operation
at higher supply voltage and will improve power supply decoupling
and noise suppression.
Ordering Information
VCOs are available in either tape and reel or tube packaging. To
order devices in tape and reel requires the suffix TR be added to
the part number, i.e. V42100TR. Quantity 1500 per 13 inch reel,
see Application Note M2037.
