Description
The MA46580,MA46585 and MA46H130 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 the elimination of package parasitics make
these varactors very attractive for voltage controlled
oscillators that require linear tuning. These tuning
diodes are useful at frequencies as high as 40 Ghz.
The beam lead design eliminates almost all of the
package parasitics resulting in improved linearity of
the junction capacitance change with applied re-
verse bias voltage. This improves tracking between
diodes and can improve VCO linearity.

Notes:
1. Capacitance is measured at 1 MHz.
2. All junctions are hyperabrupt with nominal
Γ= 1.0 or 1.25
3. Reverse voltage (VB) is measured at 10 microamps.
Applications
These beam lead constant gamma tuning varactors
are particularly useful in broadband VCO’s, where
linear frequency tuning is an important feature.
They are also very useful for FM modulating a
source for telecommunication transmitter and in
many cases such circuits can be designed without
a linearization circuit.
