Description

M/A-COM’s MACPES0004 is a high performance 75 Ohm

Coupler, in a SM-132 low cost, surface mount package. The

MACPES0004 is specifically designed for extremely low

intermod distortion in CATV applications. The MACPES0004

required the use of a 6+/-5%uH shunt inductor and a series

1500+/-5% pF capacitor on the input and a 3300+/-5% pF

series capacitor on the output to meet the performance char-

acteristics below.
