high-speed digital circuit on a wireless board should run only near the PCB s digital ground plane to minimize the current loop area, and thus decrease loop emissions and stray electromagnetic pickup Tracks should be properly terminated into 50 ohms to minimize reflections and, if these traces are over 2 inches per nanosecond long, then 50-ohm microstrip should be adopted (the maximum track length, in millimeters, should not be more than 46 times the fastest rise or fall time, in nanoseconds, to avoid transmission line effects) If the proper tracks are not employed, or the correct terminations are not used, then ringing and stair stepping of the digital waveform will be created, as well as antenna-like effects (causing EMI) Even when utilizing microstrip, minimize vias along the microstrip to avoid adding capacitance, which lowers the track s impedance, causing delays, a higher VSWR, and reflections Any stub (a short length of copper trace) situated off the main signal track, and which terminates into any high impedance, should be avoided, as this forms an open stub The open stub would act as an undesired bandstop filter at a certain frequency of /4 VP (see Sec 62, Distributed Filters )

Minimize high-impedance nodes, since these areas will add noise caused by induced currents created by EMI propagation, as well as ground loops, which create noise and EMI through induction Adding extra ground planes between signal tracks of a multilayer board will shield other tracks from electromagnetic coupling, thus reducing cross talk, and permit increased AC coupling to the ground reference plane It is always wise to check all traces on a PCB design for cross talk at the early layout phase This can be accomplished by employing field solver or cross talk software Openings made for connectors, LEDs, switches, and thermal vents within metal enclosures or ground planes can act as slot antennas, especially if the opening is greater than one-tenth wavelength, radiating the fundamental and/or its harmonics Keep the power supply separated from the digital and analog sections by shielding and decoupling Shield the synthesizer and the VCO to prevent EMI from entering the oscillator circuit, causing spurs in their output The use of power planes, which are separate copper layers on a multilayer board that are each attached to the hot end of the power supply, at RF frequencies can cause them to become patch-like antennas, sending spurious signals around the immediate PCB area Utilizing simple traces for supplying the DC, with adequate decoupling, is all that is recommended for dealing with most high-frequency designs Attempt to physically separate high-speed digital circuits from the analog circuits, or allow the digital circuits to function only when the analog circuitry is not being affected adversely, with the RF traces located as far from the digital traces as possible Modern high clock speeds mean that the propagation velocity is longer than the clock cycle, so propagation delay becomes a large consideration If this is taken into account, then the digital clock pulses can arrive properly at multiple chips and pins with equal delay

1034 Board design issues
Even if an MMIC or discrete amplifier is designed to be unconditionally stable, poor PCB layout can cause stability problems Subband oscillations (below the amplifier s bandwidth), out-of-band oscillations (above the amplifier s bandwidth), and in-band oscillations may all occur unless: 1 The amplifier is connected directly to ground 2 The PCB board itself must be connected at one-eighth wavelength points to the system ground (and preferably closer) 3 Vias must be placed from the PC board s top ground plane to the bottom ground plane to lessen the reactance between these two planes 4 VCC must be properly decoupled by using both low- and high-value capacitors for both high and low frequencies 5 All amplifier stages with high gain should be shielded to prevent them from bursting into oscillation
