Hittite announces a high dynamic range vector modulator RFIC which is suitable for wireless infrastructure applications from 1800 to 2200 MHz. The HMC500LP3 is targeted for distortion cancellation applications such as RF pre-distortion and feed-forward, as well as RF cancellation, beam forming, and amplitude/phase correction applications. The I & Q ports of the IC can be used to continuously vary the phase and amplitude of a RF signal by up to 360° and 40 dB respectively, while supporting a 3 dB modulation bandwidth of 150 MHz. The device delivers +33 dBm of input IP3 and an output noise of 162 dBm/Hz, which remains constant across the entire gain control range.
