numbers, but they are usually stored in text files and displayed in
human-readable notations, such as decimal nnn.nnn.nnn.nnn or
172.16.255.1 (for IPv4), and hexadecimal
nnnn.nnnn.nnnn.nnnn.nnnn.nnnn.nnnn.nnnn or
2C01:AB18:0:1234:FF03:567C:8:1 (for IPv6). In IPv4, each decimal
group (nnn) represents values from 000 to 255, or binary values of 8
bits. In IPv6, each hexadecimal group (nnnn) represents values from
0000 to FFFF, or binary values of 16 bits (0000 0000 0000 0000 to 1111
1111 1111 1111).
IPv6 : Internet Protocol Version 6 (IPv6) is a numerical label that is used to
identify a network interface of a computer or other network node
participating in an IPV6-enabled computer network. IPv6 uses 128 bits
for the address (as compared to an IPv4 address, which is defined as a
32-bit number). Pv6 was developed in 1995, and it is standardized as
RFC 2460. V6 began being deployed worldwide in the year 2000. I
addresses are binary numbers, but they are usually stored in text files
and displayed in human-readable notations, such as hexadecimal
nnnn.nnnn.nnnn.nnnn.nnnn.nnnn.nnnn.nnnn or
2C01:AB18:0:1234:FF03:567C:8:1 (where FFFF [Hex] = 65535 [Dec]).
Ea hexadecimal group (nnnn) represents values from 0000 to†FFFF, or
binary values of 16 bits (0000 0000 0000 0000 to 1111 1111 1111 1111).
LPA : Linear Power Amplifier (LPA) is the final amplification stage in a
multicarrier transmitter that has been designed and optimized to
produce a linear response. By operating in the linear mode, the
amplifier reduces the non-linear effects that produce intermodulation
products and side-lobe spectra that cause adjacent channel interference.
LRL : Line Reflect Line (LRL, also called TRL) method of calibration
developed by Anritsu. LRL uses two (or more) transmission lines and a
reflect standard (for each port). The line lengths are important because
the two lines look electrically distinct at all times (meaning it will not
work at DC, nor at a frequency where the difference in length is an
integral number of half wavelengths). The reflect standard is not too
important because it is only assumed to be symmetric (the same at both
ports) and not too high a return loss (practically speaking, even 20 dB
return loss will usually work). The lines are assumed to be perfect, with
no mismatch, which usually means airlines for coaxial calibrations,
although other structures can be used. On-wafer transmission lines can
usually be very good, and this cal approach will work well if one can
handle the required probe movement.
