General Description
The HMC631LP3 & HMC631LP3E are high dynamic range Vector Modulator RFICs which are targeted for RF predistortion and feed-forward cancellation circuits, as well as RF cancellation, beam forming and amplitude/phase correction circuits. The I & Q ports of the HMC631LP3(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 200 MHz. With an output IP3 of +26 dBm and output noise floor of -160 dBm/Hz (at maximum gain setting), the IP3/noise floor ratio is 186 dB.
