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 ac-
cepts 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.
