CHP3010a98F
L-Band 6-Bit Digital Phase Shifter
GaAs Monolithic Microwave IC
Description
CHP3010a98F is an L-Band (1.2, 1.4GHz)
monolithic 6-bit digital phase-shifter with a
0-360° range and a high phase accuracy.
The typical RMS phase error is 1.5°. The
circuit provides 7dB insertion loss associated
with input and output return losses better
than 15dB under all logic states. An on-chip
DC-interface is compatible with both CMOS
(0/+3.3V) and TTL (0/+5V) logics.
The circuit is mainly dedicated to radar
systems and is also well suited for a wide
range of microwave applications and
systems.
The MMIC is developed on a robust 0.25µm
gate length pHEMT process and is also
available packaged in a standard surface
mount 32-lead QFN5x5.
Main Features
■ 1.5 deg RMS Phase error
