CHM1483-QFG
12-16GHz Direct Quadrature Modulator
GaAs Monolithic Microwave IC in SMD leadless package
Description
The CHM1483-QFG is a packaged 12-
16GHz direct quadrature modulator which
integrates a double-balanced mixer (LO
suppression and Image Rejection) and a LO
buffer. It can be used for both LSB and USB
configurations.
The circuit is mainly dedicated to Point to
Point and Point to Multi-Point systems and
also well suited for a wide range of
microwave applications.
The circuit is manufactured with a pHEMT
process, 0.5µm gate length.
It is supplied in RoHS compliant SMD
package.
