General Description
The HMC625LP5(E) is a digitally controlled variable
gain amplifier which operates from DC 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. The
HMC625LP5(E) delivers noise figure of 6 dB in its
maximum gain state, with output IP3 of up to +33 dBm
in any state. The dual mode control interface is CMOS/
TTL compatible, and accepts either a three wire serial
input or a 6 bit parallel word. The HMC625LP5(E) also
features a user selectable power up state and a serial
output port for cascading other Hittite serial controlled
components. The HMC625LP5(E) is housed in a
RoHS compliant 5x5 mm QFN leadless package, and
requires no external matching components.
