Across
2 A polynomial model for nonlinear behavior that accounts for memory effects (2 words)
5 Short for digital pre-distortion
9 mm-wave frequency best suited for high bandwidth, short-range applications due to
high atmospheric attenuation
10 Random fluctuations in the phase of a signal (2 words)
12 mm-wave band of interest at 71-76 and 81-86 GHz for backhaul
13 Short for peak to average power ratio
14 Short for surface-mount components
15 The PA transfer function is not constant over time; this is called the ____ effect
16 Device process currently best suited for today’s mm-wave MMICs according to the
cover story
18 Low phase noise signal generators usually use ____ based oscillators, which have
better performance than typical VCOs
19 Modulation scheme that has high peak to average power ratios
Down
1 The loss of signal power resulting from the reflection caused at a discontinuity (2 words)
3 Short for output third-order intercept point
4 _____ phase noise represents the phase noise of a signal generator not including the
reference section
6 Device process that tends to offer a little more gain and slightly lower minimum NF than
PHEMT, but has lower breakdown voltages and power densities
7 Results primarily from the thermal noise present in the generator; most of this is contributed
by the PA in the output section (3 words)
8 Inductor designed to block (have a high reactance to) higher frequencies
10 Preprocessing the signal to a PA in order to improve its linearity
11 Using a divide-by-2 divider with a signal generator, the output frequency’s phase noise
will be ___ lower than the phase noise of the input frequency
17 Generally the phase noise at offsets greater______ is limited by this noise floor
