Description
Alpha’s MIS Chip Capacitors are available in a wide range
of sizes and capacitance values. They are frequently used
in applications requiring DC blocking, and RF bypassing,
or as a fixed capacitance tuning element in filters,
oscillators, and matching networks. The devices have a
dielectric composed of thermally grown silicon dioxide over
which a layer of silicon nitride is deposited. This dielectric
possesses a low temperature coefficient of capacitance,
very high insulation resistance. The devices also exhibit
excellent long term stability making them suitable for high
reliability applications. The capacitors have a high
dielectric breakdown which permits the use of thin
dielectrics resulting in larger capacitance per unit area than
our previous catalog offerings. The temperature coefficient
is less that 50 ppm/°C, and operation is suitable from
-65°C to 200°C. Compared to ceramic capacitors,
Skyworks’ MIS chip capacitors offer higher Q, and a lower
insertion loss of 0.04 dB, in a 50
Ω
system. Insulation
resistance is greater than 10
5
M
Ω.
To accommodate high
volume automated assembly methods, wafers can be
supplied on expanded film frame. To reduce cost, chips
can be supplied with only sample testing packaged in vials.
Packaging in waffle packs with 100% electrical test and
visual inspection is always available if required.

Performance Data
Tests on typical MIS capacitors at L and S band show
insertion loss to be 1/2 to 1/3 that of equivalent ceramic
type capacitors, without any of the associated resonance
problems. Power tests indicate that the only limitation is
the actual breakdown voltage of the device (see data
section). A typical insertion loss versus frequency graph
is shown in Figure 1. This data is taken from an actual tests
circuit with series mounted beam-lead or chip capacitors
on a 50
Ω
microstrip transmission line. The apparent
higher loss at lower frequencies on the lower capacitance
units is strictly due to the capacitive reactance of the
capacitor.
