Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has introduced two new highly integrated Vector Modulator RFICs which are ideal for distortion cancellation and beamforming networks in virtually all wireless infrastructure applications including Cellular/3G and WiMAX/4G systems from 700 to 2700 MHz. The HMC630LP3(E) and the HMC631LP3(E) are GaAs HBT Vector Modulator RFICs which are rated from 700 to 1000 MHz and from 800 to 2700 MHz, respectively. The HMC630LP3(E) and the HMC631LP3(E) high dynamic range Vector Modulator RFICs are 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 HMC630LP3(E) and the HMC631LP3(E) can be used to continuously vary the phase and amplitude of a RF signal by up to 360 degrees and 40 dB respectively, while supporting a 3 dB modulation bandwidth of up to 180 MHz. The HMC630LP3(E) and the HMC631LP3(E) Vector Modulator RFICs deliver +34 dBm of input IP3 and an output noise floor of -160 dBm/Hz, which remains constant across the entire gain control range. The HMC630LP3(E) and the HMC631LP3(E) Vector Modulators are more compact and more consistent alternatives to hybrid and MIC based vector modulator sub-assemblies. The HMC630LP3(E) and the HMC631LP3(E) are housed in pin compatible and RoHS compliant 3x3 mm QFN leadless SMT packages, and consume less than 95 mA from a single +8V supply. Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company’s e-commerce site or via direct purchase order. Released data sheets are available on-line at www.hittite.com.
