Vector Multiplier Performs Gain And Phase Control

A two-channel vector multiplier, the ADL5390 can replace as many as six discrete components usually required for gain and phase control in wireless infrastructure equipment. Operating over a frequency range of 10 MHz to 2.7 GHz, the device accepts two input signals, which are summed at the output. If the two signals are applied in quadrature, the device enables simultaneous gain and full 360° phase control, eliminating the need for discrete amplitude and phase shifters. If two independent signals are applied, it can combine channels or switch from one to another, which is useful in diversity radio transceiver applications. A broadband Cartesian (I/Q) interface enables the user to adjust each channel. The device is packaged in a 4 mm x 4mm LFCSP that operates over the range of –40°C to +85°C. Price is $7.50 each/1,000.
