General Description
The HMC500LP3(E) is a high dynamic range Vector Modulator RFICs which are targeted for RF predistortion and feed-forward cancellation circuits, as well as RF cancellation and beam forming amplitude/phase correction circuits. The I & Q ports of the HMC500LP3(E) can be used to continuously vary the phase and amplitude of RF signals by up to 360 degrees and 40 dB respectively, while supporting a 3 dB modulation bandwidth of 150 MHz. With an input IP3 of +33 dBm and input noise floor of -152 dBm/ Hz (at -10 dB maximum gain setting), the input IP3/ noise floor ratio is 185 dB.
