Constant Phase IF Limiter
CPL, MCPL & UMCPL Series
2˚ Typical Phase Shift over the Dynamic Range • 70dB Dynamic Range
±1dB Output Level Variation over -45˚C to +85˚C • Single Channel and Matched Channel Models
Pascall's range of constant phase IF limiting amplifiers is designed for
applications where phase deviations must be minimised over a wide dynamic
range. All models are available as single units, as matched pairs or as triplets.
The CPL series IF limiting amplifiers incorporate multiple limiting stages,
output filters, buffered output stages and temperature compensation to
minimise variations in phase deviations and limited IF output level.
