General Description
The HMC628LP4(E) is a digitally controlled variable
gain amplifier which operates from 50 to 800 MHz,
and can be programmed to provide anywhere from
8 dB attenuation, to 15 dB of gain, in 1.0 dB steps.
The HMC628LP4(E) delivers noise figure of 5 dB in its
maximum gain state, with output IP3 of up to +35 dBm
in any state. The dual mode control interface is CMOS/
TTL compatible, and accepts either a three wire serial
input or a 5 bit parallel word. The HMC628LP4(E) also
features a user selectable power up state and a serial
output port for cascading other Hittite serial controlled
components. The HMC628LP4(E) is housed in a
RoHS compliant 4x4 mm QFN leadless package, and
is available in three evaluation board configurations,
depending on the application frequency.
