Angle Measurement
Chris
Coulston
The
Angle Resolving Component (ARC) is an angle measurement
device that enables Chris to calculate the inclination
of hills as he rides his bicycle. The PIC16F84A-based
portable system generates highly accurate readings.

Attenuation: Resistors at RF
Ed
Nisley
The
tracking generator on Ed’s spectrum analyzer produces
RF at levels too high for receivers. He built an
attenuator so he could study his radio’s behavior.
But like capacitors, resistors can behave in unexpected
ways at high frequencies. This month Ed studies
signal levels and takes a closer look at resistors
at RF. p. 36

Attenuation, RF,
resistors, power measurement, Tee, Pi

Surface-Mount Technology Guide
Jeff Bachiochi
Are you nervous about working with surface-mount
technology (SMT)? Jeff was too, which is why he
stuck with through-hole parts for such a long time.
But times are changing, and many parts are currently
available as only surface-mount devices. Read on
if you want to conquer you fear of SMT once and
for all. p. 70

SMT, guide, sizes, form, packaging, layout,
BGA, tools, solder paste, rework
