Hittite has introduced two new highly integrated vector modulator RFICs which are optimised for distortion cancellation and beam-forming 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 modulators which are rated from 700 to 1000 MHz and from 800 to 2700 MHz, respectively. The high dynamic range modules 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 and Q ports of the modules can be used to continuously vary the phase and amplitude of an RF signal by up to 360° and 40 dB respectively, while supporting a 3 dB modulation bandwidth of up to 180 MHz. The 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 modulators are compact and consistent alternatives to hybrid and MIC based vector modulator sub-assemblies. They are housed in pin compatible and RoHS compliant 3 x 3 mm QFN leadless SMT packages, and consume less than 95 mA from a single +8 V supply.
