CHC3014
RoHS Compliant
X-band RX-TX Core Chip
GaAs Monolithic Microwave IC
Description
The CHC3014 is a Receive and Transmit
X band Core Chip.
It includes a 6 bit phase shifter, a 6 bit
attenuator, a second 2 bit attenuator for
tuning, self-biased buffers, switch and TTL
compatible parallel interfaces.
This device is manufactured 0.25 µm
pHEMT process, including via holes
through the substrate.
