Description
The MA46580 through 589 series of beam lead constant
gamma tuning varactors are hyperabrupt junction gallium
arsenide diodes with a constant gamma of 1.0 or 1.25. The
high Q values and elimination of package parasitics make
these varactors very attractive for voltage controlled oscil-
lators that require linear tuning. These tuning diodes are
useful at frequencies as high as 40 GHz.
The beam lead design eliminates almost all package par-
asitics resulting in improved linearity of the junction
capacitance change with voltage. This improves tracking
between diodes and can improve VCO linearity.
The standard capacitance tolerances is ±20%. Tighter tol-
erances of ±10% and ±5% are available. Matched pairs or
sets are also available with the above tolerances.
Applications
These beam lead constant gamma tuning varactors are
particularly useful in broadband VCOs, where linear fre-
quency tuning is an important feature. They are also very
useful for FM modulating a source for telecommunication
transmitters and in many cases such circuits can be
designed without a linearization circuit.
