A Balanced Ka-band Vector Modulator MMIC

A very broadband Ka-band vector modulator was developed using a commercial foundry to produce a high reliability MMIC for space applications. TriQuint's 0.15 mm PHEMT GaAs process was chosen for the fabrication because of its high performance, high rel...

Traditional microwave transmitter systems can be simplified by replacing up-converting mixers and associated filters with a vector modulator that directly modulates data onto a carrier signal using orthogonal I and Q control inputs for simultaneous amplitude and phase control. The versatility of the vector modulator allows unlimited modulation control...
