Modern mobile communication systems use band-limited linear modulation schemes, such as multi-level quadrature amplitude modulation (QAM) and quadrature phase shift keying (QPSK), which have high peak-to-average power ratio characteristics. For these systems, linear power amplifiers are needed to prevent adjacent channel interference. A power amplifier operated sufficiently below the...

Bonding Films The CuClad 6250 and 6700 are low melting point bonding films that have been developed for lamination of stripline or other multilayer circuits fabricated from CuClad or other company PTFE-based laminates. Dielectric constants of 6250 and 6700 bonding films fall in the midrange of CuClad® and DiClad®...
