To compensate the phase deviation
originating in the via, a short stripline is added into the circuit.
Similar to the phase deviation
, for small injected charges, the amplitude change is 
The filter features absorption up to 65 GHz, increasing attenuation up to 100 GHz, group delay variation <7 psec up to 65 GHz, and linear phase deviation
of <8[degrees] up to 43 GHz.
This circumstance allows to evaluate the thickness of the high loss composites via recording of resonant frequency or phase deviation
The Model 66AXX also features a low unit-to-unit phase deviation
at low frequency, making it suitable for modal analysis.
In the 3G applications, as well as many 2G and 2.5G improvement, there is an increasing demand on RFIC performance with respect to linearity, gain variation, phase deviation
and output power.
Essentially, all methods measure the frequency or phase deviation
of the source under test in either frequency or time domain.
There is a direct relationship between FM noise and phase noise since frequency deviation is equal to the rate of change of phase deviation
(see Application Note 2).
The [S.sub.11]results are in a good agreement through 6 GHz, with some noticeable phase deviation
Amplitude is [plus or minus]0.25 dB and phase deviation
is [plus or minus]3[degrees] between ports from 0.5 to 18 GHz.
The phase deviation
clearly has rms power given by E[(msin[[omega].sub.m]t).sup.2] = [m.sup.2]/2 [rad.sup.2].
The first rule is obvious and applies to systems with high chip rate and multipath resolution: Keep the digital clock phase deviation
at a minimum.
