Electrical Specifications
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.
