Product Overview

The CMD176P4 is a GaAs MMIC 4-bit phase shifter

housed in a leadless 4x4 mm plastic surface mount

package. The CMD176P4 operates from 13 to 17 GHz

and provides 0 to 360 degrees of monotonic phase

coverage, with a LSB of 22.5 degrees. The device is

controlled with single bit positive logic of 0 or +3 V and

features an insertion loss of 8 dB and a phase error of ± 5

degrees. The CMD176P4 is a 50 ohm matched design

which eliminates the need for external DC blocks and RF

port matching.
