HMC742ALP5E

HMC742ALP5E is a digitally controlled variable gain amplifier that operates from 70MHz to 4GHz and can be programmed to provide from -19.5dB attenuation, to 12dB of gain, in 0.5dB steps. The HMC742ALP5E delivers a noise figure of 4dB in its maximum gain state, with an output IP3 of up to +39dBm in any state. The dual mode gain control the interface accepts either a three-wire serial input or a 6bit parallel word. The HMC742ALP5E also features a user-selectable power-up state and a serial output for cascading other serially controlled Hittite components. Applications include cellular/3G infrastructure, WiBro / WiMAX / 4G, microwave radio & VSAT, test equipment and sensors, IF & RF applications.
