General Description

The HMC707LP5(E) is a digitally controlled variable gain amplifier which operates from 700 MHz to 1200 MHz, and can be programmed to provide between -2.5 dB attenuation and 29 dB of gain, in 0.5 dB steps. The HMC707LP5(E) delivers noise figure of 0.8 dB in its maximum gain state, with output IP3 of up to +38 dBm. The dual mode gain control interface accepts either three wire serial input or 6-bit parallel word. The HMC707LP5(E) also features a user selectable power up state and a serial output for cascading other Hittite serially controlled components. For 1900 MHz applications please refer to the HMC708LP5(E) data sheet.
