General Description
The HMC708LP5(E) is a digitally controlled variable
gain amplifier which operates from 1700 MHz and
2200 GHz, and can be programmed to provide
between 2.5 dB attenuation and +29 dB of gain, in
0.5 dB steps. The HMC708LP5(E) delivers noise
figure of 1 dB in its maximum gain state, with output
IP3 of up to +37 dBm. The dual mode gain control
interface accepts either three wire serial input or
6 bit parallel word. The HMC708LP5(E) also features
a user selectable power up state and a serial
output for cascading other Hittite serially controlled
components. For 900 MHz applications please refer
to the HMC707LP5(E) data sheet.
