Hittite has introduced two new digital variable gain amplifiers (VGA) which are targeted at automotive, broadband, cellular/3G, WiMAX/4G, test and measurement equipment and military applications between 500 MHz and 6 GHz. The HMC742HFLP5E is a wideband, 6-bit device which operates from 500 MHz to 4 GHz and can be programmed to provide from 19 dB attenuation to 12,5 dB of gain, with 0,5 dB resolution. The HMC625HFLP5E operates from 500 MHz to 6 GHz and can be programmed to provide anywhere from 13,5 dB attenuation to 18 dB of gain, in 0,5 dB steps. Both devices feature user selectable power-up states and a serial output for cascading other Hittite serially controlled components.
